Abstract
A multilayer composite body includes thermoplastic layers and layers of natural fibers bound with thermoplastic synthetic material. The composite body has at least one reinforcing layer made of an open-cell fabric of melting fibers. The reinforcing layer is penetrated on one or both sides by the melting thermoplastic synthetic material of adjoining natural-fiber layers and is integrated there for reinforcement. The reinforcing layer can also be disposed in addition or only between natural-fiber and pure thermoplastic layers or between thermoplastic layers. Such a composite body has excellent mechanical properties, in particular with regard to bending stress and impact resistance.
Claims16
A multilayer composite body for the production of components or preforms, comprising:
- thermoplastic layers each being a single layer and having synthetic materials;
- natural fiber layers bonded with thermoplastic synthetic material;
- and
- at least one reinforcing insert adjacent to said thermoplastic layers and said natural fiber layers, said at least one reinforcing insert having an open-pored fabric formed from fibers, said fabric penetrated from at least one side by melted synthetic materials of at least one of said adjacent natural fiber layers and said adjacent thermoplastic layers integrating into and reinforcing said at least one of said adjacent natural fiber layers and said adjacent thermoplastic layers;
- said thermoplastic layers forming outer surfaces of said multilayer composite body and forming at least one molded functional element exclusively on at least one of said outer surfaces, said functional element selected from the group consisting of a fixing strip and a rib.
A motor vehicle component or preform produced from a multilayer composite, comprising:
- thermoplastic layers each being a single layer add having synthetic materials;
- natural fiber layers bonded with thermoplastic synthetic material;
- and
- at least one reinforcing insert adjacent to said thermoplastic layers and said natural fiber layers, said at least one reinforcing insert having an open-pored fabric formed from fibers, said fabric penetrated from at least one side by melted synthetic materials of at least one of said adjacent natural fiber layers and said adjacent thermoplastic layers integrating into and reinforcing said at least one of said adjacent natural fiber layers and said adjacent thermoplastic layers;
- said thermoplastic layers forming outer surfaces of said multilayer composite body and forming at least one molded functional element exclusively on at least one of said outer surfaces, said functional element selected from the group consisting of a fixing strip and a rib.
