LFT, CFP, FRP, CFRT Continuous Fiber Reinforced Composite Production Line Product Description

Product application:

Military, spaceflight, ships, automotive lightweight, electronics, wind and electricity, construction, medical, sports and leisure, and other fields.

Continuous fiber-reinforced composite material is made of reinforced fiber material:

glass fiber(GF), carbon fiber(CF), aramid fiber(AF), ultra-high molecular polyethylene fiber(UHMW-PE), basalt fiber(BF) by using special process technology to makes high strength continuous fiber and thermal plastic&thermosetting resin soak with each other. Then extrusion and drawing processes are used to form the high strength, high toughness and recyclable thermal plastic resin composite material .commonly used plastic are PET, ABS, PP, PC, PA, PPS, POM, and other environmentally friendly thermoplastic materials.

Machining Process and applicaiton

LFT, long fiber reinforced thermoplastic, is LongFiber reinforced Thermoplastics, compared to conventional fiber-reinforced thermoplastics. Typically, fiber lengths in fiber-reinforced thermoplastics are less than 1 mm, while in LFT, fibers The length is generally greater than 2 mm, and the current processing technology has been able to maintain the fiber length in the LFT above 5 mm. The long fiber is impregnated with a special resin system to obtain a long strip that is sufficiently wetted by the resin and then cut into the desired length as needed. The most used matrix resin is PP, followed by PA, and also uses PBT, PPS, SAN, and other resins. Only different fibers are needed for different resins to achieve better results; depending on the end-use, the finished product can be Strips, which can also be strip-shaped, width-width boards, or even rod-shaped, can be used directly to replace thermoset products.

LFT-D-ILC is called Long Fiber reinforced Thermoplastics-Direct processing-In LineCompounding. LFT-D is a process technology for the direct production of long fiber reinforced thermoplastic composites. The key factor distinguishing it from GMT and LFT-G is that the semi-finished product step is omitted and the material selection is more flexible. In the LFT-D technology, not only the fiber content and length but also its matrix polymer can be directly adjusted to the requirements of the final part. The number of additives can change and affect the mechanical properties of the product and the properties of the particular application materials, such as thermal stability, colorability, UV stability, and fiber-to-substrate bonding characteristics, which also means each special application. All of them are available in LFT-D for their unique material formulation.

The impact resistance of the LFT-D press-formed product is slightly lower than that of the GMT, but its impact resistance is significantly higher than that of the LFT-G because it is much longer than the fiber after LFT-G molding. In addition, according to a large number of studies, the productivity of LFT-D injection molding is higher than that of standard LFT-G pellets, because the low plasticization requirement of LFT-D improves the fiber breakage condition. For parts with a molding cycle of more than 1 min, the LFT-D injection molding equipment can be completed in 30 seconds.
