Effect of Polylactic Acid (PLA) On Mechanical and Physical Properties of Polypropylene (PP)

Composite materials are preferred because of many reasons such as better mechanical properties, cheaper and lighter compared to the traditional material. In this study, polypropylene was used as the matrix and polylactic acid was employed as the reinforcement. PP and PLA, show partial compatibility...
