A Study on the Weldability of Fiber Glass Reinforced Polyethylene (Part 1)

On the Molding Properties

Abstract

In the present paper, we try to study the molding property and the weldability of fiber glass reinforced polyethylene. Fiber glass reinforced polyethylene is a composite material of the reinforced engineering plastics and the polymer is its main matrix. It presents a difficult property of matter because glass fiber is mixed as the reinforcing agent with polymer (that has the organic physical property), which has makes fiber glass reinforced polyethylene a more complex structure. Therefore its coalescence (for example, molding or welding) becomes one of the difficult and serious problems. However the reinforcing of engineering plastics is one of the important problems to be solved in the future study of engineering materials of plastics and, above all, its bonding is a problem one should not ignore. In this paper we describe an experimental study of its molding property. Fiber glass reinforced thermoplastics used for experimental study had a low density polyethylene as the matrix, random mat of glass fiber as reinforcing agent.
The following summary can be made from the results of the present experiment. Fiber glass reinforced ployethylene could acquire'satisfactory properties by the proper treatment before molding.
