Paul Joachim Prause founded the company Schichtstofftechnik Prause in 1974, which changed its name to P.J. Prause Durotec GmbH in 1998. Previously, as a member of 3M Germany with its fibre composite ScotchplyTM, P. J. Prause had played a decisive role in the development of technical applications for composite leaf springs, in Germany and in Europe. Consequently, Prause Durotec now has more than 30 years of experience in the fabrication and application of springs made from fibre composites. Prause Durotec is a medium sized company with 16 employees and a worldwide client base.
