Longsheng continuous fiber reinforced thermoplastic composite semi-finished products into the field of automotive interior. Europe, a car company carrying its off-road vehicles in the rear seat system using thermoplastic composite materials. The car Sensor in the vehicle rear seat in the middle of the configuration of the load device, to achieve the seat back independent. The production of the load components using the molding and re-injection technology.
The new part weighs more than four percent of the steel, and the safety component can withstand the load because its semi-finished fabric has a continuous fiber thickness of only 2 millimeters, which is designed to withstand mechanical stress. The component was developed by Brose Fahrzeugteile GmbH and the LANXESS High Performance Materials Division provided Brose with support and produced the component at a factory in Coburg, Germany. For the sake of function, the load device is intended to be mounted on the side Fuel Rail Pressure Sensor of the rear seat, which is capable of withstanding bending and torsion forces. In response to these load conditions, the designers for this paragraph within the thermoplastic composite glass glass fiber towel selected multi-axis design. Multi-axis Tepex is Bond-Laminates's new development results, through a complex process will Tepex fiber and tape combination, significantly enhance the strength of these composite sheet. The core layer of the load device semi-finished product is divided into four layers, each layer thickness of 0.25 mm, the longitudinal axis of the component as a benchmark, the fiber forward degree (fiber orientation) is ± 45 °, for the absorption of torque. The outside also has two layers, each layer thickness of 0.5 mm, for the absorption of bending force, 80% of the continuous fiber and the force in the same direction.
In the case of a frontal impact, the multi-axis design ensures that this lightweight component can withstand the impact of the acceleration load in the trunk of the car and can withstand inertial forces in the event of a rear-end collision to prevent the passenger from being squeezed. In addition to the ribs to enhance the stiffness of the components, there are a large number of functional components such as head restraints, mounting points and threaded interfaces, and embedded recesses around the load, which are integrally molded with the assembly during injection molding. If the traditional steel structure design, the functional components must be separately welded or tightened. In the production Temperature Sensor of this load structure of the process, the first semi-finished products into the injection mold blank, the use of glass fiber reinforced thermoplastic injection molding, the use of the injection technology used. In addition to the ribs to enhance the stiffness of the components, there are a large number of functional components such as head restraints, mounting points and threaded interfaces, and embedded recesses around the load, which are integrally molded with the assembly during injection molding. The use of conventional steel structure design, the functional components must be separately welded or tightened.
LANXESS developed a overhanging simulation system that optimized the mold of the load device as an important part of its HiAnt service. Through the overhanging simulation, various molding strategies can be visualized and evaluated. These results in the beginning will be introduced into the mold design, significantly reducing the development time. LANXESS has derived the design of semi-finished billet on the basis of this particular mold technology. The blank is preformed, or the parts are locally secured in place within the mold before Pressure Sensor the mold is fully closed. The technology prevents the formation of wrinkles, but also to avoid the semi-finished molding process of continuous fiber over-stretching.
