Abstract
In the contour of bio-composites, the technique of gamma irradiation to alter the surface of the natural fiber is very effective and economical. Composites manufactured using poly lactic acid along with natural fiber such as luffa cylindrica (LC), treated with various doses (0.5 Gy, 1 Gy and 2 Gy) of gamma irradiation of 6 MV energy to study their response on the structural, tensile and flexural characteristics. Preliminary results suggest promising mechanical properties. After reinforcement of irradiated LC fiber, the tensile strength and flexural strength of the virgin PLA matrix increases by 60% and 155% respectively. With increase of fiber content in composite, the modulus is enhanced of the composites. In conjunction to this, LC fiber before reinforcement is modified with Ca salts to delve into biomedical territory and study its uses.
