  • Publication number: 20100038817
    Abstract: A method and device for the production of thermoplastics containing coarse-scale and/or nanoscale, coated, de-agglomerated magnesium hydroxide particles that are supplied to the thermoplastic in the form of a dispersion or suspension in an aqueous or organic solvent, and mixed with the themoplastic. The thermoplastics filled with magnesium hydroxide particles demonstrate improved mechanical properties, particularly an improved modulus of elasticity and low brittleness.

  • Patent number: 6673452
    Abstract: The invention relates to the field of chemistry and to a fiber composite material which is used, for example, in aircraft. The invention provides a fiber composite material in which delamination can be significantly reduced. This is achieved by a fiber composite material with multiple layers, each containing a duromer matrix and reinforcing fibers, inner layers contain fibers featuring a high level of adhesion to the duromer matrix, outer layers contain fibers featuring a low level or no adhesion to duromer matrix. There is also provided a method in which the reinforcing fibers include a coating and the layers are structured in such a way that, on the interior of the fiber composite material, layers are arranged which contain fibers with a high level of adhesion to the duromer matrix and that outer layers which contain fibers with a lower or low level of adhesion, or no adhesion to the duromer matrix are arranged on and/or around these inner layers.
