Xiamen, ChinaPLA, also known as polylactic acid, is a biodegradable and environmentally friendly polymer. Its production process is pollution-free, and the material can naturally degrade, making it one of the most representative green plastics.
The structure of PLA has a significant impact on its heat resistance, toughness, mechanical strength, degradability, and biocompatibility. Among these, heat resistance is a key limitation.
PLA molecular chains contain only one methylene group, forming a spiral structure with low chain mobility. As a result, PLA exhibits slow crystallization during injection molding, leading to low crystallinity and poor heat resistance. Additionally, during thermal processing, ester bonds may break, generating terminal carboxyl groups that accelerate thermal degradation through autocatalysis.
Long fiber reinforcement significantly enhances the performance of PLA. Fibers act as a structural skeleton within the polymer matrix, restricting molecular chain movement under heat and thereby improving thermal resistance.
Various fibers can be used for PLA reinforcement, including:
Among these, carbon fiber and glass fiber are widely applied due to their high strength and modulus, while natural fibers are gaining attention for their sustainability and biodegradability.
Studies show that reinforced PLA composites can achieve a Vicat softening temperature exceeding 140°C, significantly improving thermal performance compared to pure PLA.
Compared to short fiber reinforced materials, long glass fiber (LGF) composites offer superior mechanical performance:
