Long Carbon Fiber30 PP Composite Black Color For Injection Grade

About the Carbon Fiber

Carbon fiber can improve the elastic modulus of polypropylene, but reduce the tensile strength, impact strength and elongation at break.

The carbon fiber has a certain heterogeneous nucleation effect on PP, which increases the non-isothermal crystallization peak temperature and grade of PP matrix, and promotes the formation of β crystal type in PP matrix. Polypropylene is easy to nucleate and crystallize at the end of carbon fiber section during isothermal crystallization. EPDM-g-MAH and SEBS-g-MAH have good dispersion in PP matrix, which significantly improves the impact strength and elongation at break of PP. The PP/CF composite material with EPDM-g-MAH and SEBS-g-MAH has higher impact strength and elastic modulus.

The addition of toughening agent in PP/CF composite results in the decrease of nucleation ability and crystallization growth rate of PP matrix. The crystal type of PP/CF composite was not changed by the toughening agent. The nucleation of carbon fiber became obvious in the PP/CF composite, and the spherulites mainly grew near the carbon fiber.

Application

Case

PP plastics account for 46.5% of automotive plastic consumption. Zhu Furong, deputy general manager of Automotive lightweight Business Department of Sinochem International (Holding) Co., LTD., pointed out that the density of modified PP can be reduced by reducing the proportion of talc powder, etc. Compared with traditional PP, weight can be reduced and injection molding time can be shortened.

Low density PP material used in bumper, door panel and other parts has a significant weight reduction effect, at the same time, the resistance to friction and coloring performance is better. Composites of PP and carbon or glass fiber can also replace metal in pedestrian protection beams, intake manifels, and sub-instrument panel frames for lightweight.

Frequently asked questions

1. What are the main features and advantages of long fiber reinforced thermoplastics?

Compared with traditional short fiber materials, the main features of LFT-G thermoplastic long glass fiber and long carbon fiber are mechanical properties, high impact and tensile modulus, which are more suitable for some large products or structural load-bearing parts. It can do Injection molding, extrusion of sheets, profile pipes, etc. and it is Simple processing.

2. The cost of long fiber products is higher. Does it have a high recycling value?

The thermoplastic LFT long fiber material can be recycled and reused very well.
