Definitions
- the present invention relates to a fiber composite material comprising one or more fiber layers of a fiber material and a polycarbonate-based composition as a matrix material, and a multi-layer composite material of at least two layers of fiber composite material.
- the fiber layer (s) is / are embedded in the matrix material.
- the present invention further relates to a method for producing these fiber composite materials or multilayer composite materials and the components or housing parts made of these (multilayer) composite materials.
- Fiber-containing multilayer composite materials having a thermoplastic-based matrix are referred to as "organosheets" both in the following and in the prior art.
- Organosheets have compared to extruded plastic plates without fiber reinforcement on a higher strength and rigidity and even on the strength and rigidity of metallic sheets zoom or can even exceed.
- the importance of such materials e.g. As housing parts in the electrical and IT industry, but also in the automotive and aircraft industry, is steadily increasing.
- These composites have a high rigidity with outstanding mechanical properties. Compared to conventional materials such as steel, they also have a significant weight advantage.
- Another advantage of such polymer-supported multilayer composite materials is the risk of corrosion reduced or completely excluded by the absence of steel.
