摘要: A composite of I a prepreg made of a solid mixture of a reactive plastic resin and a reinforcing means in the form of a tissue or a fiber and II a removable release film comprising a multilayer structure of a) a release layer of at least one thermoplastic homo- or copolymer of α,β unsaturated olefins and at least one wax-like compound as a release additive, b) optionally an adhesion promoting layer, c) a layer of at least one thermoplastic polyamide homo- or copolymer, d) optionally an adhesion promoting layer, e) a release layer of at least one thermoplastic homo- or copolymer of α,β unsaturated olefins having a release coating based on a cured polysiloxane, f) a laminate adhesive layer, and g) a release layer of at least one thermoplastic polyester and a wax-like compound as a release additive.
