摘要

Polylactide (PLA) is a biodegradable, compostable, thermoplastic polymer produced from corn, an annually renewable resource. In moving towards developing a sustainable vehicle, use of materials such as PLA could greatly contribute to the goal of a more environmentally friendly vehicle. To date, several non-automotive applications of PLA have been commercialized. These include PLA fiber/textile applications for clothing, carpeting, and linens; as well as blow molded articles for food packaging. Thus far for automotive use, a single niche application of compression molded PLA has been developed. Here, we seek to optimize the injection molding process conditions and composition of PLA composites for automotive interior applications. The effects of adding various reinforcements to the PLA resin for property improvements were assessed. Crystallinity, modulus, and strength properties were evaluated by differential scanning calorimetry (DSC), tensile and flexural testing.
