FEATURE “Automotive” LFT concentrated pellets: performance at lower cost Automotive structural parts require a high level of mechanical and design performance. In that sense, long-fibre thermoplastic (LFT) materials make thermoplastic composites more attractive than metal regarding automotive functions such as weight savings, cost reduction and recycling requirements. PHILIPPE PARDO, LFT & TWINTEX® PRODUCT AND SALES DEVELOPMENT, SAINT-GOBAIN VETROTEX he increasing use of long-fibre thermoplastic composite materials in the industry to replace metal solutions is due mainly to their design flexibility and improved mechanical properties (good stiffness, high impact resistance even at low temperature, good creep behaviour, etc.). Short-fibre engineering thermoplastic resins have some limitations in replacing metal components: the mechanical properties of reinforced thermoplastics are directly linked to the fibre L/D ratio and for a specific glass fibre diameter, they are directly related to the residual fibre length of the reinforcement. T component design and manufacturing process simulations as well. The success stories and technical feedback on the design of automotive structural parts (LFT front end carriers, for example) has led automotive OEMs to think about new functions like instrument panels, door modules, visible parts, etc. In the future, LFT materials will be used not only to provide a reinforcing solution, but also to add other properties like low VOC & fogging emissions, flame retardancy and UV resistance. Long-glass-fibre PP concentrate material like Twintex® pellets will make it possible to fulfil these requirements, while keeping an excellent cost/performance ratio and processing flexibility with standard injection units. Effect of residual glass fibre length on mechanical properties. What is Twintex®? Effect of residual fibre length on multiaxial rupture performance. LFT is not just a material or a process. Rather, it is a global system combining thermoplastic resins, additives and reinforcing fibres (no longer considered as a filler) that covers In the past, few thermoplastic resins reinforced with continuous glass fibre were developed, due to the high viscosity of thermoplastic matrices. The first patents for these materials were taken out in the early 70’s. Now, various types of thermoplastic composite materials are available. One of these is Saint-Gobain Vetrotex’s Twintex®, a revolutionary dry prepreg produced by commingling continuous glass and PP filaments. JEC Composites Magazine / No34 July-August 2007
