ABSTRACT:
A composite material, and a process for making the same, comprises a matrix of a semi-crystalline polyolefin homopolymer or copolymer of any molecular weight, and a reinforcement material comprising textile and/or metal materials coated with a layer for permitting adhesion between the reinforcement material and the matrix. The layer comprises at least one elastomer component and is intimately bonded to the polyolefin matrix by means of a relatively thin coating. The coating on the adherized reinforcement material includes a polyolefin with an average molecular weight of at least 500,000.
