How is long glass reinforced polypropylene ( LGF ) made?
2021-09-26
Long fiber PP modified material is made by impregnation.PP raw resin material is heated and melted, evenly covered on the fiber of different glass fiber content, such as fully impregnated strip after cold water cooling, after the granulator will cut the fiber strip into 6-25mm particle length. Impregnation process can make glass fiber & carbon fiber orderly arrangement, so that the shear parti...

Typical applications of long glass fiber reinforced plastics in the automotive industry
2023-07-04
Long fibre reinforced thermoplastics (LFT) is the most commonly used base resin for LFT, followed by PP, PA and also PBT, PPS, PPA, TPU and other resins. It is worth mentioning that different fibers are needed for different resins to achieve better results. Development of LFT In 1980, Polymer Composites Corporation (PCI), USA, was the first to propose the theoretical design concept of LFT, and con...

Automotive Interior Odors: An Unavoidable Challenge for Material Engineers
2025-07-10
Odor is both a sensory experience and a perceived measure of quality. In the confined space of a car cabin, the "new car smell" from plastics is not a symbol of luxury—instead, it often becomes a major source of consumer complaints. This article, grounded in engineering practice, systematically explores the sources, mechanisms, analytical methods, and controllable strategies related to odor. It ai...
