TPF² – an award-winning technology

JEC Europe 2014 - TPF² = technical progress + lightweight design + lightweight material.

The development department of HBW-Gubesch (Bavaria, Germany) managed to shorten the process chain – originally consisting of forming and joining processes – for a LWRT (low weight reinforced thermoplastic) component. The process was developed together with Dr. Ing. h.c. F. Porsche AG.

So far, the most common way to reduce the weight of undershields with requirements for impact strength, bending stiffness, acoustical absorption and low grammage was to use a semi-finished composite with a sandwich structure, e.g. based on a multilayered LWRT resin such as Quadrant’s Symalite.

The TPF² process combines the forming of the LWRT main board and of the GMT with a joining procedure for the involved materials, with a simultaneous local adaption of additional LWRT reinforcement sections (LWRT Doppler). This way, a GMT-LWRT junction that does not present a structural weakening anymore is achieved.

Thus, the characteristics of the complete component are improved, and the process costs and component weight are reduced. In addition, TPF² reduces processing time by 50% to 90 seconds. In 2013, this method received the AVK prize, an award for remarkable innovations in the composite industry. TPF² is used in a serial application for sports car undershields with 27,000 units per year.
