Composites, produced of different fiber reinforced plastic layers, offer the possibility to create light-weight structures with tailored non-isotropic properties. Natural fibers like flax, kenaf and cotton shoddy are combined with either thermoplastics or thermosettings. In the first production step fleeces as mixtures of natural and polymer fibers or out of fibers and resin powder are produced. In the second step the compression molding influences the properties like strength, young’s modulus and also the acoustical absorption coefficient. The used technology for heating, molding and cooling has also a major impact on the economics.
