Application and advantages of basalt fiber long fiber reinforced thermoplastic composite materials

Introduction of Basalt Fiber

Basalt continuous fiber material is known as the “new material of the 21st century”, basalt ore as raw material, the ore is crushed and added to the furnace, at 1450 ℃ ~ 1500 ℃ melting, the uniform melt through the drawing funnel plate first pulled into crude fiber, and then the crude fiber by the wire drawing machine made of various sizes of continuous fibers and according to the subsequent use of different infiltration agent for infiltration treatment, processing to form the final product. Then the crude fiber is drawn into various sizes of continuous fiber by the drawing machine, and according to the subsequent use of different impregnating agent for impregnation treatment, processing to form the final product.

Basalt fiber long fiber reinforced LFT composites characteristics

Basalt fiber with high strength, high and low temperature resistance, good durability, corrosion resistance, non-absorbent, good dielectric properties, radiation protection, good wave-transparent and wave-absorbent properties, cost-effective and moderate characteristics, commonly used in reinforcing thermoplastic composites, long-fiber-reinforced basalt fiber LFT composites products have the following characteristics:

• Under high temperature and long time low load conditions, it will not produce deformation with good dimensional stability.
• Fatigue resistance, high temperature resistance, low warpage, aging resistance, less fiber exposure, superior surface performance.
• Small creep performance, small anisotropy, low warpage, density <1.6g/m3
• Good wave-transparent and wave-absorbing properties, good fluidity, good molding performance, can be injection molding or extrusion molding.
• Excellent mechanical properties, especially impact resistance, low water absorption, good seawater and salt spray resistance.
• It can still maintain its performance in low temperature environment and will not be degraded by UV and electromagnetic radiation.
