Transparent and light PP Long Glass Fiber composite material thermoplastic resin sample free

PP-LGF material

Physical property

PP filling long glass fiber material has high hardness, rigidity and strength, has excellent heat resistance and chemical resistance, not easy to be damp.

Molding

PP filling long glass fiber material has good fluidity, easy to shape processing. ABS material needs to use high temperature and high pressure injection molding process because of its strong viscosity.

Application

PP filling long glass fiber material has excellent heat resistance, chemical resistance and hardness characteristics, widely used in automobile, electronic appliances, communication equipment, medical instruments and other fields.

Why filling Long Glass Fiber?

Good dimensional stability

Excellent fatigue resistance

Small creep properties

Low anisotropy and low warpage deformation

Excellent mechanical properties, especially impact resistance

Good fluidity, suitable for thin-wall product processing

10~25mm long glass fiber reinforced polypropylene (LGF-PP) compared with ordinary 4~7mm short glass fiber reinforced polypropylene (GF-PP) has higher strength, stiffness, toughness, dimensional stability and low warpage. In addition, long glass fiber reinforced polypropylene has better creep resistance than short glass fiber reinforced polypropylene even if it is subjected to 100℃.

On the injection molding product, the long glass fiber interleaved into a three-dimensional network structure, even after the polypropylene substrate is burned, the long glass fiber network still forms a certain strength of the glass fiber skeleton, while the short glass fiber after burning generally into a non-strength fiber skeleton. This is mainly because the length-diameter ratio of reinforced fibers determines the reinforcement effect. Fillers with critical aspect ratio less than 100 and short glass fibers have no reinforcement effect, while long glass fibers with critical aspect ratio greater than 100 have reinforcement effect.

Compared with metal materials and thermosetting composites, long glass fiber plastics have low density and can reduce the weight of the same parts by 20% to 50%. Long glass fiber plastics can provide designers with greater design flexibility, such as forming parts with complex shapes, integrating the number of parts used, Save the mold cost (generally the cost of long glass fiber plastic injection mold is about 20% of the cost of metal stamping mold), reduce energy consumption (long glass fiber plastic production energy consumption is only 60%~80% of steel products, 35%~50% of aluminum products), simplify the assembly process.

Application of long glass fiber reinforced polypropylene to automobile parts

Long fiber reinforced polypropylene is used in car dashboard body frame, battery bracket, front end module, control box, seat support frame, spare placenta, fender, chassis cover plate, noise partition, rear door frame, etc.

Front-end module: For automotive front-end module, LGFPP(LGF content 30%) material, radiator, horn, condenser, bracket and more than 10 traditional metal parts can be integrated into a whole; Compared with metal parts, more corrosion resistance, low density, weight reduction of about 30%, with higher design freedom, can be directly recycled without classification treatment; Reduce the manufacturing cost, have obvious cost reduction advantage.

Instrument panel skeleton: for the soft instrument panel skeleton material, LGFPP material than filled PP material has higher strength, higher bending modulus, better mobility, under the same strength, the instrument panel design thickness can be reduced to reduce weight, the general weight reduction effect is about 20%. At the same time, the traditional multi-component dashboard bracket can be developed into a single module. In addition, the material selection of the instrument panel front defrosting air duct body and the instrument panel middle skeleton is generally the same material as the instrument panel body skeleton, which can further improve the weight reduction effect.

Seat back: replacing the traditional steel skeleton can achieve 20% weight reduction, and has excellent design freedom and mechanical properties, expanded riding space and other features.
