PLA plastic PLA is a non-natural polyester, which is considered as one of the most promising "green plastics" because of its excellent properties such as biocompatibility, biodegradability and high mechanical strength. PLA has good degradability and can be completely degraded by microorganisms. Products made of PLA can be completely degraded to CO2 and water after use, and are non-toxic and non-irritating. PLA has similar mechanical properties to polypropylene, while its gloss, clarity and processability are similar to polystyrene, and its processing temperature is lower than that of polyolefin. PLA can be processed into various packaging materials, fibers and nonwovens through injection molding, extrusion, blistering, blow molding, spinning and other general plastic processing methods, and PLA has been widely used in disposable plastic products. In addition, PLA can also be widely used in chemical, medical, pharmaceutical and 3D printing industries. It is now increasingly recognized that PLA polyesters will play a key role in solving the plastic pollution problem. PLA reinoforced plastic Glass fiber (English name: glass fiber or fiberglass) is an inorganic non-metallic material with excellent performance, the advantages of good insulation, heat resistance, good corrosion resistance, and high mechanical strength. One of the main uses of glass fiber for the reinforcement of composite materials. Long glass fiber generally refers to the length of more than 10mm glass fiber. Long Glass Fiber Reinforced PLA plastic refers to modified PLA composites containing glass fiber lengths of 10 to 25 mm, which are formed into a three-dimensional structure with glass fiber lengths greater than 3.1 mm through injection molding and other processes, and is referred to as Long Glass Fiber PLA, abbreviated as LGFPLA. fiber reinforce thermoplastic). From the material definition, LGFPLA is a kind of LFT. Generally, they are columnar particles of 12mm or 25mm in length and about 3mm in diameter. The pellets of about 12mm length are mainly used for injection molding, while the pellets of about 25mm length are mainly used for compression molding. In these pellets, the glass fiber has the same length as the pellets, and the glass fiber content can vary from 20% to 60%, and the color of the pellets can be color-matched according to customer requirements.

PA12 information Long carbon chain nylon is a nylon with amide group in the main chain repeating unit of nylon molecule, and the length of methylene group between two amide groups is more than 10. We call it as long carbon chain nylon, including nylon 11, nylon 12, etc.. PA12 is nylon 12, also known as poly(dodecalactam) and poly(laurolactam), which is a kind of long carbon chain nylon. The basic raw material for polymerization is butadiene, a semi-crystalline - crystalline thermoplastic material. Nylon 12 is the most widely used long carbon chain nylon, it has most of the general properties of nylon, in addition to low water absorption, and has high dimensional stability, high temperature resistance, corrosion resistance, good toughness, easy processing and other advantages. Compared with PA11, another long carbon chain nylon material, PA12's raw material butadiene is only one-third the price of PA11's raw material castor oil, and can be used in most scenarios instead of PA11, and has wide applications in many fields such as automotive fuel hoses, air brake hoses, submarine cables, and 3D printing. Among long-chain nylon, PA12 has great advantages compared with other nylon materials, its advantages are the lowest water absorption, lowest density, low melting point, impact resistance, friction resistance, low temperature resistance, fuel resistance, good dimensional stability, good anti-noise effect, etc. PA12 has the properties of PA6, PA66 and polyolefin (PE, PP) at the same time, to achieve the combination of lightweight and physical and chemical properties, with performance It has the advantages of light weight and physical and chemical properties. PA12-LCF If the base material is compared to concrete, the fiber is like steel reinforcement, and mixing the two is like adding steel reinforcement to concrete. If there is only concrete, the castings will easily crack under external forces, but once the high-strength reinforcement is added to it and the concrete wraps it sufficiently, they will become a single unit. When the object is subjected to external forces, the rebar can withstand most of the external forces, making the structural strength of this whole very high. Carbon fiber has many excellent properties, high axial strength and modulus of carbon fiber, low density, high specific performance, no creep, resistance to ultra-high temperature in non-oxidizing environment, good fatigue resistance, specific heat and electrical conductivity between non-metal and metal, small coefficient of thermal expansion and anisotropy, good corrosion resistance, good X-ray transmittance. Good electrical and thermal conductivity, good electromagnetic shielding, etc. Compared with traditional glass fiber, carbon fiber has more than 3 times of Young's modulus; it is about 2 times of Young's modulus compared with Kevlar fiber, which is insoluble and swollen in organic solvents, acids and alkalis, and has outstanding corrosion resistance. Nylon itself is an engineering plastic with excellent performance, but moisture absorption, poor dimensional stability of products. Strength and hardness is also far from metal. In order to overcome these shortcomings, as early as before the 70s. People have used carbon fiber or other varieties of fibers for reinforcement to improve its performance. Carbon fiber reinforced nylon materials have developed rapidly in recent years, because nylon and carbon fiber are excellent performance in the field of engineering plastics materials, its compound material synthesis reflects the superiority of the two, such as strength and rigidity than unreinforced nylon is much higher, high temperature creep is small, thermal stability has improved significantly, good dimensional accuracy, wear resistance. Excellent damping, compared with glass fiber reinforced has better performance. Therefore, carbon fiber reinforced nylon (CF/PA) composites have developed rapidly in recent years.

PA66-LGF Information PA66 is one of the most produced and widely used polyester series products. It has high grain size, excellent tensile properties, bending properties, tensile strength and other material mechanical properties, and its excellent ultra-low temperature characteristics and organic chemical properties. It is a class of rubber products with wide range of application, stable characteristics, good mechanical properties, high quality insulation, low density, easy processing and molding, self-extinguishing, and good wear resistance. Therefore, it is widely used in vehicles, electronic and electrical, chemical materials, industrial equipment, instrument panels, construction projects and other industries. However, it has high water absorption, poor alkali resistance, dry ultra-low temperature impact, low compressive strength and easy to deform after absorbing moisture, which affects the reliability of goods specifications. People have improved PA66 in a variety of ways, adding PA66 chemical fiber is one of them. After adding glass fiber, its impact force, heat deformation, material mechanical properties, molding processability and acid resistance are significantly improved. Glass fiber is a class of functional raw materials with high quality characteristics. This utility model has the advantages of low cost, non-combustibility, high temperature resistance, acid resistance, high tensile strength, high impact compressive strength, low tensile strength, high quality insulation properties, high quality insulation properties, etc. It is usually used as a raw material to improve organic chemical polymers or functional materials and composites. The most important hazard of proportional limits to raw materials is mechanical properties. The material mechanical properties of modified PA66 are also related to the composition of glass fibers. The tensile strength, bending strength and impact compression strength of PA66 increase with the glass fiber composition after the addition of PA66 chemical fibers. The tensile and flexural strengths of the managed system increased linearly, but the glass fiber composition was 30%. The trend of increasing tensile and flexural strengths showed some improvement. The results show that PA66 can produce a reasonable page layer, which can reasonably transfer the ground stress between the matrix and page, and thus improve the compressive strength of the matrix.

PA6 material PA6 is one of the most widely used materials in the current field, and PA6 is a very good engineering plastic with balanced and good performance. The raw materials for the manufacture of nylon 6 engineering plastic are extensive and inexpensive, and it is not restricted by the technological monopoly of foreign companies. However, in order to make good use of this inexpensive and excellent material, we must first understand it. Today, we will start with glass fiber reinforced PA6 engineering plastics, because it is the most important category of PA6 engineering plastics. Just like any other engineering plastics, PA6 has advantages and disadvantages, such as high water absorption, low temperature impact toughness and dimensional stability is relatively poor. So engineers will use different methods to make PA6 better, which we call modification. At present, the most common method is to blend and modify PA6 with glass fiber (GF). Today, we will take a look at the mechanical properties of PA6 engineering plastics under the glass fiber GF system for reference and help us select materials. PA6-LGF 1. Influence of glass fiber content on PA6 engineering plastics We can find from the application and experiment that the content index is often one of the biggest influencing factors in fiber reinforced composites. As the glass fiber content increases, the number of glass fibers per unit area of the material will increase, which means that the PA6 matrix between the glass fibers will become thinner. This change determines the impact toughness, tensile strength, bending strength and other mechanical properties of glass fiber reinforced PA6 composites. In terms of impact performance, the increase of glass fiber content will greatly increase the notch impact strength of PA6. Taking long glass fiber (LGF) filling PA6 as an example, when the filling volume increases to 35%, the notch impact strength will increase from 24.8J/m to 128.5J/m. But the glass fiber content is not more is better, short glass fiber (SGF) filling volume reached 42%, the impact strength of the material reached the highest 17.4kJ/㎡, but continue to add will let the gap impact strength showed a downward trend. In terms of bending strength, the increase of the amount of glass fiber will make the bending stress can be transferred between the glass fiber through the resin layer; At the same time, when the glass fiber is extracted from the resin or broken, it will absorb a lot of energy, thus improving the bending strength of the material. The above theory is verified by experiments. The data show that the bending elastic modulus increases to 4.99GPa when the LGF (long glass fiber) is filled to 35%. When the content of SGF (short glass fiber) is 42%, the bending elastic modulus reaches 10410MPa, which is about 5 times that of pure PA6. 2. Influence of glass fiber retention length on PA6 composites The fiber length of the glass fiber also has an obvious effect on the mechanical properties of the material. When the length of the glass fiber is less than the critical length (the length of the fiber when the material has the tensile strength of the fiber), the interface binding area of the glass fiber and the resin increases with the increase of the length of the glass fiber. When the composite material is broken, the resistance of the glass fiber from the resin is also greater, so as to improve the ability to withstand the tensile load. When the length of glass fiber exceeds the critical, the longer glass fiber can absorb more impact energy under impact load. In addition, the end of the glass fiber is the initiation point of crack growth, and the number of long glass fiber ends is relatively less, and the impact strength can be significantly improved. The experimental results show that the tensile strength of the material increases from 154.8MPa to 164.4MPa when the glass fiber content is kept at 40% and the length of the glass fiber increases from 4mm to 13mm. The bending strength and notched impact strength increased by 24% and 28%, respectively. Moreover, the research shows that when the original length of the glass fiber is less than 7mm, the material performance increases more obviously. Compared with short glass fiber, long glass fiber reinforced PA6 material has better appearance warping resistance, and can better maintain mechanical properties under high temperature and humidity conditions. TDS for your reference PA6 can be made into long glass fiber reinforced material by adding 20%-60% long glass fiber according to the characteristics of the product. PA6 with long glass fiber added has better strength, heat resistance, impact resistance, dimensional stability and warping resistance than without glass fiber added. Following TDS show the data of PA6-LGF30. Application PA6-LGF has the largest proportion of applications in the automotive industry, by electronic and electrical applications, and also involving machinery and engineering ...
