Performance and Application introduction of basalt long-fiber reinforced thermoplastic
Performance and Application introduction of basalt long-fiber reinforced thermoplastic
In the modified engineering plastics industry, long-fiber-reinforced thermoplastic refer to composite materials produced by long carbon fiber, long glass fiber, Aramid fiber or basalt fiber and polymer matrix through a series of special modification methods. The biggest Performance of long-fiber composite materials is that they have superior properties that the original materials do not have. Today,we will introduce to you the basalt fiber long fiber reinforced thermoplastic composite material (LFT-B)and its application in the long fiber reinforced thermoplastic composite material (LFT).
1. Introduction of basalt fiber
Continuous Basalt fiber is known as new material of 21st century. Basalt stone as raw materials and crushed the putted into furnace.After melt at 1450-1500℃, the homogeneous melt is first drawn into coarse fibers through the drawing bushing, and then crude fibers are drawn into continuous fibers of various specifications by wire drawing machines, and is infiltrated with different sizing according to different purpose,and processed to form the final products.

2.Performance of BF LFT
Basalt fiber have the Performances of high strength, excellent heat resistance,excellent durability, corrosion resistance, non-absorbent, excellent dielectric performance,radiation protection,excellent wave penetration and absorption performance,moderate price. It’s often used for reinforce thermoplastic composite material. BF LFT products have following performances:
l Under high temperature and long-term low load conditions, no deformation will occur and excellent dimensional stability.
l Fatigue resistance, high temperature resistance, low warping, aging resistance, less fiber exposure, excellent surface performance.
l Small creep performance, small anisotropy, low warping, density is lower than 1.6g/m3
l excellent wave penetration and absorption performance, excellent fluidity, excellent molding performance, can be injection molded or extruded.
l Excellent mechanical properties, especially impact resistance, low water absorption, excellent resistance to seawater and salt spray.
l It maintains its properties at low temperatures and is not degraded by UV and electromagnetic radiation.
3.Application of Basalt Fiber Long Fiber Reinforced LFT Composites
