In 1974, Paul Joachim Prause founded the company Schichtstofftechnik Prause, which was renamed the P. J. Prause Durotec GmbH in 1998. P. J. Prause had previously, as part of 3M Germany, significantly contributed to shaping the technical application of synthetic leaf springs in Germany with Scotchply™ glass-fibre composites. This enabled Prause Durotec GmbH to acquire more than 35 years of experience in the manufacture and application of leaf springs made from fibre composites. Prause Durotec is a medium-sized company with 16 members of staff and a global customer base. The range of products we manufacture includes all configurations of flat leaf springs with E-glass, S-glass, carbon fibres, with epoxy resin providing the matrix. The procedures used to process the UD prepregs (UD = unidirectional) comply with aeronautical and military standards.
