Title: **Innovative Contributions of Bernd Wohlmann in Composite Materials**
Introduction
Bernd Wohlmann, an accomplished inventor based in Dusseldorf, Germany, has made significant strides in the field of composite materials with a total of six patents to his name. His innovative approaches have been pivotal in enhancing the performance and efficiency of composite structures, particularly through the development of advanced fiber yarns and preforms.
Latest Patents
Wohlmann's most recent patents focus on the creation of an impregnated reinforcing fiber yarn and its application in manufacturing composite materials. His first highlighted patent outlines a pre-impregnated yarn that consists of a bundle of reinforcing fiber filaments, imbued with a specific resin composition. This innovative approach utilizes a first resin made from urethane, aromatic polyisocyanates, and polyalkylene glycol, ensuring that the filaments are not only impregnated but also partially bonded through this resin.
Additionally, Wohlmann has developed a fiber preform that incorporates unidirectional fiber tapes. This preform is uniquely designed, featuring a wall composed of a first zone made from reinforcing fiber bundles treated with one resin composition, and a second zone formed from unidirectionally directed reinforcing yarns utilizing another resin composition. Such configurations allow for a high proportion of reinforcing fibers—over 35 vol %—ensuring superior structural integrity and performance in composite materials.
