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.
