LFT LFRT material Introduction-What is LFT LFRT material?
LFT/LFRT material, long fiber reinforced thermoplastic composites,is reinforced thermoplastics with fiber lengths greater than 10 mm, and the reinforcing fibers are mainly glass fibers, carbon fibers and other fibers. The effect can be achieved with the appropriate fiber surface treatment.
The addition of fiber material to the resin can greatly improve the overall material performance. Fiber composites absorb external forces in three ways: fiber pullout, fiber breakage, and resin fracture. The increase of fiber length consumes more energy for fiber pull-out, which is beneficial to the improvement of impact strength;
the end of fiber in the composite is often the initiation point of crack growth, and the small number of long fiber ends also makes the impact strength increase; the long fiber blends entangle, flip and flexural each other when filling the mold, unlike the short fiber blends which are arranged in the flow direction, therefore, the long fiber blends molded products are better than the same molded parts of short fiber blends. Therefore, compared with the same molded parts of short fiber blends, the long fiber blends have higher isotropy, better straightness and less warpage, so the dimensional stability is better.
The heat deflection temperature of long fiber reinforced thermoplastics is also higher than that of short fiber reinforced thermoplastics. Therefore, long-fiber composites exhibit better performance than short-fiber composites, which can improve rigidity, compression strength, bending strength, and creep resistance. Thermoplastic composites are divided into long-fiber reinforced and short-fiber reinforced types.
LFT material includes the long glass fiber filled resin (LFT-LGF series) and the long carbon fiber filled resin (LFT-LCF series), such as LFT-PP have LFT-PP-LGF, LFT-PP-LCF material, And LFT material has LFT-PP,LFT-PA6/PA66/PA12, LFT-PPS, LFT-ABS,LFT-PEI,LFT-PEEK etc high performance material.More LFT material, please contact us: Candyhu@lfrtplastic.com www.lfrt-plastic.com
