/Long Glass Fiber Polypropylene Technology For Automotive Applications
Long Glass Fiber Polypropylene Technology For Automotive Applications 2021-01-28
Replacing steel with plastic is the most important way to lighten cars at the present stage. Replacing metal with plastic, for example, modifying PA,PA6,PP and other materials with long fibers.LFT-G modified PP has good mechanical properties, small density, chemical corrosion resistance and other characteristics.

According to relevant statistics, the amount of modified PP materials used in automobiles accounts for about 50% of the plastics used in automobiles.The long fiber modified PP material is one of the most commonly used automotive interior materials.It is often used to make instrument panels, door panels and other interior decoration, but the surface of the scratch resistance is poor.The addition of fiber or filler with spherical microstructure (such as talcum powder, silica silica powder, glass beads, etc.) can improve the hardness and modulus of the modified polypropylene PP, and improve the scratch resistance to a certain extent.

high strength thermoplastics

The high strength performance of PP modified materials can ensure the collision resistance of cars and reduce losses and costs.With the advancement of automobile production technology and the production of modified materials, the combination of long fiber modified materials and high strength steel can be used in the roof beam column, front beam column, threshold beam, C column, etc.This can increase the torsional stiffness of the body and reduce the weight of the body.

In addition, long fiber modified PP material is also widely used in wheel hub, brake system, transmission system, interior and exterior decoration, engine field.
Benefits of the application of LFT-G in the automotive industry:
1. High integration: a part can integrate a variety of functions, reduce the cost of the mold and processing molding time;
2. Manufacturing process optimization: compact structure, reduce installation steps, easy assembly, easy installation, disassembly and maintenance;

3. Corrosion resistance: the whole body is corrosion-resistant, which can meet the requirements of corrosion resistance.
