PLA PLA (polylactic acid) is also known as polylactic acid, the production process of polylactic acid is pollution-free, and the product can be biodegradable to achieve recycling in nature, so it is an ideal green polymer material, and one of the representatives of biodegradable plastics. The structure of PLA has important influence on its heat resistance, toughness, mechanical strength, degradability and biocompatibility. The influence on heat resistance is mainly discussed below. There is only one submethylene on the main chain of PLA molecule, the molecular chain has a spiral structure, and its activity is poor. As a result, the PLA after injection molding almost does not crystallize due to slow crystallization speed, so the heat resistance of the product is poor. During hot processing, the ester bond is partially broken to produce terminal carboxyl group, which plays an autocatalytic degradation effect on the thermal degradation of PLA. LGF reinforced PLA The rigidity of the fiber makes it play the role of skeleton support in the polymer matrix. When the polymer is heated, the movement of the chain segment is limited, thus improving the heat resistance of the material. At present, the fibers that can be used for enhancement modification of PLA include natural plant fiber (sisal, flax, linen, bamboo, coconut, wood fiber, etc.), natural animal fiber (silk, etc.), mineral fiber (basalt fiber, etc.), and chemical fiber (carbon fiber, glass fiber, etc.). Among these fibers, carbon fiber and glass fiber are widely used for their high strength and high modulus. Natural plant fiber has been widely studied because of its wide source, degradability and improved thermal and mechanical properties of composites. Modified natural fiber and modified inorganic fiber (glass fiber or carbon fiber) were mixed into the PLA matrix to prepare two kinds of fiber reinforced PLA composites. The test results show that the Vica softening temperature of the composites exceeds 140℃. Compared with Short fiber(SGF) Compared with the short fiber, it has more excellent performance in mechanical properties. It is more suitable for large products and structural parts. It has 1-3 times higher (toughness) than short fiber, and the tensile strength (strength and rigidity) is increased by 0.5-1 times.

HDPE Introduction High-density polyethylene is an opaque white waxy material, lighter than water, specific gravity of 0.941 ~ 0.960, soft and tough, but slightly harder than LDPE, but also slightly elongated, non-toxic, odorless. Flammable, can continue to burn after leaving the fire, the upper end of the flame is yellow, the lower end is blue, will melt when burning, there are liquid drops, no black smoke, at the same time, emitting the smell of paraffin wax when burning. Acid and alkali resistance, organic solvent resistance, excellent electrical insulation, low temperature, can still maintain a certain degree of toughness. Surface hardness, tensile strength, rigidity and other mechanical strength are higher than LDPE, close to PP, tougher than PP, but the surface finish is not as good as PP. Poor mechanical properties, poor air permeability, easy to deformation, easy to aging, easy to brittle, brittle than PP, easy stress cracking, low surface hardness, easy to scratch. Difficult to print, when printing, surface discharge treatment is required, can not be plated, and the surface is not glossy. HDPE-Long glass fiber Because of its high crystallinity, poor impact strength and environmental cracking resistance and other defects, limiting its scope of application, so a lot of toughening modification HDPE research work has been carried out at home and abroad. Our company has greatly improved the performance of HDPE through the way of co-blending modification. Long fiber reinforced thermoplastic composites are reinforced thermoplastics with fiber lengths greater than 10mm. The reinforcing fibers are mainly glass fibers, carbon fibers, etc. Depending on the type of resin with appropriate fiber surface treatment, better results can be achieved. The addition of fiber material to the resin can greatly improve the overall material performance. Fiber composites absorb external forces in three ways: fiber pullout, fiber breakage, and resin fracture. The increase of fiber length consumes more energy for fiber pull-out, which is beneficial to the improvement of impact strength; the end of fiber in the composite is often the initiation point of crack growth, and the small number of long fiber ends also makes the impact strength increase; the long fiber blends entangle, flip and bend each other when filling the mold, unlike the short fiber blends which are arranged in the flow direction, therefore, the long fiber blends molded products are better than the same molded parts of short fiber blends. Therefore, compared with the same molded parts of short fiber blends, the long fiber blends have higher isotropy, better straightness, less warpage, and therefore better dimensional stability; the heat deflection temperature of long fiber reinforced thermoplastics is also increased than that of short fiber blends. Therefore, long-fiber composites exhibit better performance than short-fiber composites, which can improve rigidity, compression strength, bending strength, and creep resistance.

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 ...
