ABSTRACT:
A composite material, especially suitable for chemical apparatus construction is formed of a layer of a thermoplastic synthetic resin and a textile layer pressed onto the resin layer in the heated condition. The textile layer is a mechanically prestrengthened, polyester fiber mat bound chemically with a binder consisting of a synthetic resin dispersion of polymers and/or copolymers of esters of acrylic and methacrylic acid and of acrylonitrile. Needling is a preferred procedure for mechanically prestrengthening the mat.
