Abstract (en)

[origin: WO2022129045A1] The invention relates to a process for producing a fiber-reinforced composite material (organosheet) containing at least one thermoplastic molding compound, at least one continuous reinforcing fiber layer and at least one inorganic filler material. According to the invention, at least one sheet material consisting of continuous reinforcing fibers is embedded in a matrix composition comprising at least one thermoplastic molding compound, the thermoplastic molding compound including at least one thermoplastic polymer and optionally at least one polarity-functionalized polymer that contains repeat units of at least one functional monomer. The invention also relates to the composite materials produced according to the claimed method.
