Light weight PP filled long glass fiber Car seat back

PP filled long glass fibe Details

10~25mm long glass fiber filled PP (abbreviated LGFPP) has higher strength, stiffness, toughness, dimensional stability and low warpage than ordinary 4~7mm short glass fiber reinforced PP (abbreviated GFPP). In addition, long glass fiber reinforced polypropylene materials do not produce significant creep even when subjected to high temperatures of 100 ° C, and have better creep resistance than short glass fiber reinforced polypropylene. On the injection molded product, the long glass fiber filled PP is interlaced to form a network structure. Even after the polypropylene substrate is burned, the long glass fiber network still forms a glass fiber skeleton with a certain strength, and the short glass fiber generally has no strength after burning. Fiber skeleton. This situation is mainly caused by the aspect ratio of the reinforcing fibers determining the reinforcing effect, the critical long diameter = L / D, the critical length to diameter ratio of less than 100 filler and short glass fiber without reinforcement, and the critical length to diameter ratio is less than 100 Glass fiber plays a reinforcing role.

Long Fiber's Uniqueness

Compared with metal materials and thermosetting composites, long glass fiber reinforced PP has low density and the same component weight can be reduced by 20~50%. Long glass fiber reinforced PP can provide designers with greater design flexibility, such as complex shape. Parts, integrated parts use, saving mold costs (usually long glass fiber plastic injection mold costs about 20% of the cost of metal stamping molds), reducing energy consumption (long glass fiber plastic production energy consumption is only steel products 60~80%, 35~50% of aluminum products), simplifying the assembly process.

Application Range

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

Car Seat back: replaces the traditional steel frame to achieve 20% weight loss, excellent design freedom and mechanical performance, expanded seating space, etc.
