Composite materials on the basis of renewable resources

The invention relates to composite materials on the basis of renewable resources, using reinforcing materials on the basis of natural fibres. Duro-plastics on the basis of oleochemically cross-linkable systems are described as matrix material. These contain as principal ingredients derivatives of oleochemical fatty substances, such as epoxidized fatty substances, fatty substances modified by carboxylic acid or carboxylic anhydride as well as (meth)acrylate-modified fatty substances and fatty substances containing amino groups. Synthetic comonomers and/or coreactants can possibly be added to said oleochemical duro-plastics. Using all conventional manufacturing technology, the above composites can be used to produce components for vehicle manufacture, aircraft manufacture, the building industry, window construction, the furniture industry, the electronics industry, sports equipment, toys, machines and apparatuses, the packaging industry, agriculture or security technology.
