The present invention relates to a novel two-component system and a method for producing a semifinished component product that is stable upon storage using the two-component system, in particular sheet molding compounds (SMC) and moldings (composites) produced therefrom. Components). The method here has five steps, which comprise three different reaction steps leading to a continuous increase in hardness level. Known methods are used here for applying the two-component system to a fiber material, for example carbon fiber, glass fiber or polymer fiber, or for contacting the two-component system with short fibers, wherein the first reaction is carried out. do. This is followed by thermal polymerization initiated using radiation or plasma application or by redox initiation. The polymerization produces thermoplastics, or thermoplastic prepregs, respectively, which can then be subsequently molded. The polyol present can finally be crosslinked via elevated temperature with uretdione already present in the system. Thus, it is possible to produce dimensionally stable thermosetting materials, or composite components each crosslinked. |
