Polypropylene with long glass fiber PP lgf With the development of vehicle lightweight, modified materials have been applied to the interior, door, front circumference, seat and other parts of the car, and even a large number of modified materials have been used in the fuel tank, bumper and tail door of the car. The end of the rear door of the material has been from the traditional steel door, composite tail gate, all plastic end door direction. Now, all plastic tail inside of the door panels are long glass fiber enhanced PP + PP (LGF), plating and spoiler generally use PP long glass fiber or tpo, parts all use injection molding technology, made a series of car body parts and then are assembled by the special process. Long glass fiber reinforced PP, used in the rear door of the material density is around 1.5 commonly, can probably drop weight 1.3 kg, the other PP + additive dosage is less, long glass fiber materials have an advantage on voc detection, injection molding and extrusion molding process more efficient. Summarized above, using modified plastics in the car door, including PP, PA6, PA66, PA12, TPU, PEEK, etc., not only has good effects of weight reduction, and can save the cost of production.

Long glass fiber and long carbon fiber reinforced plastic are composite materials obtained by reinforcing two fibers to the same matrix resin. In this hybrid composite, the various fibers take full advantage of the performance and complement each other, making it a versatile, versatile performance. The hybrid enhancement method has been put into practical use and is a new development direction for the future development of composite materials. A new type of hybrid thermoplastic material; a combination of long glass fibers and long carbon fibers to form a directly moldable material that combines the strength, stiffness and durability of the fiberglass.

Long glass fiber is a filament which is quickly drawn from molten glass. It can be divided into alkali, alkali, medium alkali and special glass fiber according to raw material components, such as high silicon oxide and quartz fiber. The commonly used long glass fiber composite material refers to a resin-based composite material, which can be formed by hand-paste, winding, pressing, etc., and the Xiamen LFT composite plastic factory adopts an injection and pultrusion process. The long glass fiber reinforced composite material can be widely used in the fields of machinery, chemical industry, transportation, military and other fields due to its characteristics of light weight, corrosion resistance and insulation. Low-cost thermoplastic polymer; one of the automotive lightweight materials; as the fiber content increases, the long-fiber skeleton fiber network continues to improve durability; it can improve the strength and rigidity of the product after molding;

Carbon fiber is made of man-made chemical fiber with high carbon content and not melting during heat treatment, which is processed by thermal stable oxidation treatment, carbonization treatment and graphitization. The long carbon fiber reinforced epoxy resin composite material has the highest specific strength and specific modulus, and is the highest among the existing structural materials. In areas where density, stiffness, weight, and fatigue characteristics are critical, long carbon fiber composites are advantageous in applications where high temperatures and high chemical stability are required.
