Under the background of tightening and lightening of energy-saving and emission reduction policies and the irreversible trend of intelligence, new automotive materials have become a hot spot of concern, and the market size in the future may reach trillions of yuan.
Among many new materials, the application of lightweight materials such as “plastic generation” in automobiles has become a common practice. In particular, long glass fiber reinforced thermoplastics (LFT) are increasingly favored by automobile manufacturers and are widely used. Production of world-renowned cars such as BMW, Audi, Ford and Volkswagen.
LFT refers to a glass fiber reinforced colloidal material obtained by long, continuous glass fiber, which is fully wetted by a resin by a special process and then cut into a specific size. Usually the length of the glass is 10 to 25 mm.
As an excellent lightweight composite material, LFT is a lightweight, high-strength, modular design, reduced component count and number of processes, low cost, flexible design and corrosion resistance.
LFT materials have the following material properties: (1) excellent mechanical properties; (2) warpage; (3) product appearance.
The glass fiber formed in the long glass fiber reinforced material forms a three-dimensional network structure, can withstand large stresses and loads, and effectively absorb energy, so that the composite material can achieve better mechanical properties.
Glass fiber reinforced plastic, also known as glass fiber reinforced plastic, is a functional new type of material made from synthetic resin and glass fiber. It has the characteristics of light weight, high strength, corrosion resistance and good insulation performance. As a kind of composite material, glass fiber reinforced plastic has been widely used in aerospace, railway railway, decorative building, home furniture, building materials sanitary ware and sanitation engineering, etc. due to its unique performance advantages.
