New technology for long fibre-reinforced thermoplastics plants

News International-French

8 Feb 2013

JEC Europe 2013 - Dieffenbacher has developed a new line technology that allows the manufacture of components from long fibre-reinforced thermoplastics via direct compounding (known as LFT-D) with additional reinforcement provided by unidirectional fibre tape (UD fibre placement).

Body components are made from long fibre-reinforced thermoplastics featuring greater structural rigidity thanks to the addition of UD fibre tapes. With the development of tailored fibre placement LFT-D technology, it is now possible to discontinue inline, component-specific unidirectional fibre reinforcement and integrate the reinforcements into the component structure itself.


In cooperation with their partner KraussMaffei and automation specialists Märtiens Robotec, Dieffenbacher has also developed a fully-automated production line for the manufacture production of carbon fibre-reinforced plastic components using the high-pressure resin transfer moulding process (HP-RTM). The production system covers the system units for preform production, the press process and the subsequent reworking of components. The HP-RTM line can be configured for use in both large- and small-scale production. Dieffenbacher delivers the production line ready for immediate use.


SMC Directline: just-in-time manufacturing of semi-finished parts

The advanced D-SMC direct process opens up new potential applications for thermosetting plastic composites as part of lightweight construction in the automotive industry.

Mat-like semi-finished parts are traditionally transformed into moulded parts by means of a flow process. However, the process for maturing and storing semi-finished parts, as well as the related logistics, is both time-consuming and cost intensive. Dieffenbacher has developed a fully-automated production line for fibre-reinforced thermosetting plastics that helps avoid these costs.
