Microstructure and Properties of Ramie Fiber Reinforced LDPE Composites

-
Abstract
A kind of composite material was prepared by using low density polyethylene (LDPE) resin as matrix,and raw ramie,ramie yarn and ramie cloth as reinforcements.The tensile and thermal properties of the composite material were studied.The results show that the strengthing effect of the raw ramie is the best and tensile strength of the composite material reinforced by it reaches the maximum value of 91.494 MPa.The strengthing effect of ramie cloth is the worst.The interfacial properties of the composite material were improved after alkali treatment,and strength and elastic modulus of the comoposite material reinforced by yarn and cloth are improred obviously.The thermal stability of ramie fiber are increased.
