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.
Claims7
A composite material, especially suitable for chemical apparatus construction comprising a layer of a thermoplastic synthetic resin and a textile layer pressed onto the resin layer in the heated condition;
- said textile layer consisting of a mechanically prestrengthened, polyester fiber mat bound chemically with a binder consisting essentially of a synthetic resin dispersion of polymers of acrylic or methacrylic acid esters and/or copolymers of esters of acrylic or methacrylic acid and of acrylonitrile.
A method for producing a composite material which comprises chemically bonding the fibers of a polyester fiber mat which has been needled with a binder consisting essentially of a dispersion of polymers of acrylic or methacrylic acid esters and/or copolymers of esters of acrylic acid or methacrylic acid and acrylonitrile, and thereafter laminating the polyester mat to a layer of a synthetic resin by application of heat and pressure.
