Abstract (en)
[origin: WO2022180018A1] A fiber-reinforced composite material (K), containing a thermoplastic polymer matrix and at least one natural-fiber component, is technically advantageous if it contains at least 45% (v/v) of a styrene (co)polymer (A) as polymer matrix, 30-55% (v/v) of a natural-fiber sheet material (B) as natural-fiber component, optionally 0-10% (v/v) of an additional polymer component (C), and optionally 0-10% of at least one additive (D), the volume percentages of components (A) to (D) adding up to 100 volume percent of the composite material (K).
