The effect of the addition of 10–25 wt% coconut oil cake (COC) on the properties of poly(lactic acid) (PLA) was studied. PLA/COC (80/20) composite showed better mechanical properties and higher thermal stability than PLA. Glycerol used as a plasticizer further improved tensile and flexural mechanical properties, as well as the impact strength and the ability to suppress noise.
Being a biodegradable polymer, poly(lactic acid) (PLA) based composites receive greater preference over nonbiodegradable plastics. Poly(lactic acid) has to find its place in various applications such as polymer composites, agriculture, biomedical, etc. Polymer composites based on PLA possess comparable mechanical strength, endurance, flexibility and endures future opportunities. Several combinations...
