Mehrlagiger Verbundkörper

摘要

The invention relates to a multi-layer composite body comprising thermoplastic layers and layers of natural fibres bound with thermoplastic plastic. Said composite body has at least one reinforcing layer made of an open-cell fabric of melting fibres, which layer is penetrated on one or both sides by the melting thermoplastic plastic materials of adjoining natural-fibre layers and integrated into same for reinforcement. The reinforcing layer can also be arranged in addition or only between natural-fibre and pure thermoplastic layers or between thermoplastic layers. A composite body formed in this way has excellent mechanical properties, in particular as regards bending stress and impact resistance.
