Car Door Module PP filled long fiberglass

Product Details

Long Glass Fiber Reinforced Polypropylene (LGFPP) is one of the new varieties of attention. As a carrier material for automotive modules, this material can not only effectively improve the rigidity, impact strength, creep resistance and dimensional stability of the product, but also make complex automotive module products. Due to the strength requirements, the conventional module carrier is usually obtained by stamping a glass fiber mat reinforced thermoplastic (GMT) or a metal plate material based on polypropylene. Due to the use of press forming, it is difficult to integrate multiple parts. In order to increase the rigidity and strength and to obtain a thin forming thickness, it is also necessary to use a reinforcing rib. In addition, other steps are required to remove the flash and burrs of the molded part. All of the above factors constrain the reduction in weight and cost of automotive module products. Since metal is not suitable for forming complex shapes, it limits its use in many parts, which also hinders cost reduction. In contrast, long glass fiber reinforced plastic injection molding can overcome many of the above drawbacks. However, the glass fibers may be damaged during the injection molding process without obtaining the required strength.

ApplicationCar Door Module

◆Hyundai Sonata replaces the steel plates in the four doors with pp filled long fiberglass on the plastic door parts of the car, which reduces the total vehicle quality by about 2kg. At the same time, it promotes the modular development of the door and integrates 21 components into one injection molding. In the parts, the five assembly processes are simplified to one, which reduces the overall assembly cost of the car. In the front door module of the new Ford Fiesta model, a variety of functional components, such as door locks, door glass lifters, speakers, anti-theft devices, etc., are integrated.

FAQ

Q1:The product is easy to brittle and change long fiber reinforced thermoplastic materials can solve this problem?

A:The overall mechanical properties must be improved. The characteristics of long glass fiber and long carbon fiber are the advantages in mechanical properties. The impact performance of traditional modified materials is 1-3 times higher and the tensile strength is increased by 0.5-1 times.

Q2:Long glass fiber and long carbon fiber products are prone to floating fiber reasons and solutions?

A:Due to the low temperature of the sol or the low temperature of the mold and the low injection molding pressure, the glass fiber and the resin can not be well compatible and diffused. The uneven mold temperature on the mold surface will cause the floating fiber problem, and the sol temperature and mold temperature will be increased. Increase the injection pressure.
