Title: Rolf Doellinger: Innovator in Fiber Material Impregnation
Introduction
Rolf Doellinger is a notable inventor based in Fischbachau, Germany. He has made significant contributions to the field of fiber material technology, particularly in the impregnation processes that enhance the strength of composite materials. With a total of 3 patents to his name, Doellinger's work has had a profound impact on the industry.
Latest Patents
Doellinger's latest patents focus on innovative methods for impregnating reinforcing fiber materials with resinous binder materials. His inventions ensure that gaseous inclusions are avoided, leading to a remarkable increase in the strength of the fiber compound material. The process involves applying the liquid resinous binder material primarily to one side of the reinforcing material. This material is then moved through an absorbing zone, where it penetrates the reinforcing material completely due to a predetermined residence time and temperature. The removal of gas inclusions is achieved through adsorption and expulsion in a specially designed chamber with guide rollers. This design allows the impregnated material to reverse its moving direction repeatedly, enhancing the penetration of the resinous material and the removal of gas inclusions. Additionally, the precise weight ratio adjustment of resin to fiber material is facilitated by moving the impregnated material in a vertical orientation through a fulling station, which helps excess resin flow off effectively.
