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 ...

PPA-LGF PPA, full name polyphthalamide, is a semi-aromatic polyamide with no less than 55% terephthalic acid or phthalic acid as raw material, commonly known as aromatic high temperature nylon. PPA has better mechanical properties and high temperature resistance compared to traditional aliphatic nylon (PA6/PA66) materials. PPA materials have relatively low water absorption, good dimensional stability and good corrosion resistance. Glass fiber reinforced PPA composites have high temperature resistance, high strength and low density, and are considered to be the best resin to replace steel with plastic. Compared with traditional short fiber reinforced pellets, long glass fiber reinforced PPA composites have better physical and mechanical properties. Application Because high-temperature nylon can withstand high strength, high loads, and high temperatures in harsh environments, it is ideal for applications in engine areas (such as engine covers, switches, and connectors) as well as transmission systems (such as bearing cages), air systems (such as exhaust control systems), and air intake units. PPA engineering plastic is a high performance engineering plastic reinforced by fiber with high temperature nylon as the base material. The structure and crystalline characteristics of high-temperature nylon make it have more characteristics and excellent overall performance than nylon 66 and nylon 6 and other engineering plastics: strong rigidity, high hardness, high temperature resistance, good chemical resistance and low water absorption, dimensional accuracy and stability and low warpage, excellent fatigue resistance, in many fields including automotive parts, mechanical parts and electrical and electronic parts used in motor parts It is widely used in many fields including automotive parts, mechanical parts and electrical and electronic parts for motor parts, circuit breakers, etc. LGF VS SGF Other materials you may wonder About us Xiamen LFT composite plastic Co., Ltd is a brand-name company that focuses on LFT&LFRT.

PPS information The resin matrix of thermoplastic composites involves general and special engineering plastics, and PPS is a typical representative of special engineering plastics, commonly known as "plastic gold". Performance advantages include the following aspects: excellent heat resistance, good mechanical properties, corrosion resistance, self-flame retardant up to UL94 V-0 level. Because PPS has the advantages of the above properties, and compared with other high performance thermoplastic engineering plastics and has the characteristics of easy processing, low cost, so it becomes an excellent resin matrix for manufacturing composite materials. PPS composite material PPS filling short glass fiber (SGF) composite material has the advantages of high strength, high heat resistance, flame retardant, easy processing, low cost, and has been applied in automotive, electronics, electrical, machinery, instruments, aviation, aerospace, military and other fields. PPS filling long glass fiber (LGF) composite material has the advantages of high toughness, low warpage, fatigue resistance, good product appearance and so on. It can be used in water heater impeller, pump shell, joint, valve, chemical pump impeller and shell, cooling water impeller and shell, household appliance parts and so on. What are the specific differences between short glass fiber (SGF) and long glass fiber (LGF) reinforced PPS composites? 1. Mechanical property analysis The reinforcement fiber added in the resin matrix can form a supporting skeleton, and the reinforcement fiber can effectively bear the external load when the composite is subjected to external force. At the same time, energy can be absorbed by fracture, deformation and other ways to improve the mechanical properties of resin. The tensile strength and bending strength of the composites are gradually increased by increasing the amount of glass fiber. The main reason is that when the glass fiber content increases, more glass fiber in the composite material can withstand the action of external force. Meanwhile, due to the increase in the number of glass fibers, the resin matrix between the glass fibers becomes thinner, which is more conducive to the construction of glass fiber reinforced frame. Therefore, with the increase of glass fiber content, more stress is transferred from resin to glass fiber under external load, which effectively improves the tensile and bending properties of composite materials. The tensile and bending properties of PPS/LGF composites are higher than those of PPS/SGF composites. When the glass fiber mass fraction is 30%, the tensile strength of PPS/SGF and PPS/LGF composites is 110MPa and 122MPa, respectively. The bending strength was 175MPa and 208MPa, respectively. The flexural elastic modulus were 8GPa and 9GPa, respectively. The tensile strength, bending strength and bending elastic modulus of PPS/LGF composites are increased by 11.0%, 18.9% and 11.3% compared with PPS/SGF composites, respectively. PPS/LGF composites have higher length retention rate of glass fiber. Under the condition of the same glass fiber content, the composites have stronger load resistance and better mechanical properties. When the glass fiber content is low, the impact strength of the composite decreases. The main reason is that the lower glass fiber content cannot form a good stress transfer network in the composite material, so that the glass fiber exists in the form of defects under the impact load of the composite material, resulting in the overall impact strength of the composite material is reduced. With the increase of the glass fiber content, the glass fiber in the composite can form an effective spatial network, and the reinforcement effect is greater than that of the glass fiber tip. Under the action of external load, the external load can be transferred to the reinforced fiber better, thus improving the overall performance of the composite. In the PPS/LGF system, the length of the glass fiber is longer and the spatial network is more dense. The reinforced glass fiber has greater bearing capacity and better impact strength. When the mass fraction of glass fiber is 30%, the impact strength of PPS/LGF is increased by 19.4% from 31kJ/m2 to 37kJ/m2, and the notch impact strength is increased by 54.5%(from 7.7kJ/m2 to 11.9kJ/m2). 2. Thermal properties analysis of PPS/SGF and PPS/LGF composites When the mass fraction of glass fiber is 30%, the thermal deformation temperature of PPS/SGF composite and PPS/LGF composite reaches 250℃ and 275℃, respectively. The thermal deformation temperature of PPS/LGF composite is 10% higher than that of PPS/SGF composite. The main reason is that the introduction of glass fiber makes the network skeleton of reinforced fiber formed inside the composite material, which greatly improves the heat resistance of the composite material. The size of glass fiber in PPS/LGF is longer, and the heat resistance improvement advantage is more obvious....
