What is long glass fiber reinforced polypropylene composite?
LFT-G® Long-glass fiber reinforced polypropylene composites (LGFPP) are a type of thermoplastic material that consists of polypropylene (PP) reinforced with long glass fibers. They have become popular in industries such as automotive and construction due to their high strength, stiffness, durability, and resistance to impact and chemical corrosion.
The long glass fibers used in LGFPP composites are typically around 5-25 mm in length, which results in a high aspect ratio that enhances the material's mechanical properties. Compared to traditional short-fiber reinforced composites, LGFPP provides a higher modulus of elasticity, improved dimensional stability, and better creep resistance.
The manufacturing process of LFT-G® LGFPP involves two stages. First, the glass fibers are impregnated with the polypropylene resin by means of a melt compounding process. During this process, glass fibers are mixed with molten polypropylene that is then extruded to produce pellets or rods. In the second stage, these pellets or rods are melted and molded into various shapes using processes such as injection molding or compression molding.
Advantage and Application of LFT LGFPP
One of the main advantages of LFT-G® LGFPP composites is their ability to be used for structural applications. LFT-G® LGFPP have found numerous applications in the automotive industry, where they are used in various parts such as dashboards, door panels, and trunk liners. LFT-G® LGFPP composites also enable weight reduction in these applications due to their lower density compared to traditional materials such as steel and aluminum.
Additionally, LFT-G® LGFPP composites offer excellent corrosion and chemical resistance, which makes them ideal for use in harsh environments such as chemical processing plants and wastewater treatment facilities.
LFT-G® long-glass fiber reinforced polypropylene composites are a versatile material that offers many benefits, including high strength, stiffness, durability and resistance to impact and chemical corrosion. They have numerous applications in industries such as automotive and construction, and their benefits make them a popular choice for structural applications. With ongoing research and development, the potential uses for LGFPP composites will likely continue to expand.
