With the continuous development of science and technology, short fiber modification has become the most common modified material in the composite material industry. Its performance cannot meet the application of many materials, but the long glass fiber modified material can meet its lack of performance. PP LGF is the most advantageous material in terms of comprehensive strength, heat resistance and processing.
As the main part of the instrument panel system, the instrument panel frame is also the load-bearing structure of electrical components and other functional parts. Therefore, it is required to have high strength and high rigidity. At present, the most widely used material on the instrument panel frame is PP with the same density. The PP-LGF material replaces the traditional PP material. While meeting the relevant performance, it can improve the energy absorption performance of the instrument panel. At the same time, the design thickness of the existing instrument panel frame can be reduced from 3mm~3.5mm to 1.8mm~2.5mm, thus Reduce the weight of the instrument panel frame and promote the lightweight of car interiors.
