What are thermoplastic prepreg tape composites?
Composites have three elements
1: Matrix resin, e.g. PP, PA
2: Fiber, such as carbon fiber, glass fiber, and
3: fiber morphology, is one-dimensional, or fabric form, different weaving state has different properties;
Prepreg is a combination of resin matrix and reinforcement made by impregnating continuous fibers or fabrics with a resin matrix under strictly controlled conditions, and is an intermediate material in the manufacture of composites. Certain properties of prepregs are carried directly into the composite material and are the basis of the composite material. The properties of the composite material depend largely on the properties of the prepreg.
PP-LCF composites
Long fibre reinforced thermoplastics, LFT for short, uses PP as the most common base resin, by PA, but also PBT, PPS, SAN and other resins, just for different resins need to use different fibers to achieve better results.
In the automotive industry, LFT-PP (Long Fiberglass PP) is used in car hoods, instrument panel frames, battery trays, seat frames, car front-end modules, bumpers, luggage racks, spare tire trays, fenders, fan blades, engine chassis, roof racks, etc..
LCF V& SCF
In contrast to LFT, SFT (Short fibre reinforced thermoplastics), the biggest difference in their appearance is the difference in the length of the particles and fibers:
SFT
Particle length: 1-3 mm
Length of reinforcing fibers: 0.2 to 0.6 mm
LFT
Particle length: 6 to 25 mm
Reinforcing fiber length: 6 to 25 mm
Applications
The earliest and most mature application of LFT-PP is in automotive parts. Due to its excellent performance and cost-effectiveness, LFT-PP is increasingly being used in other fields such as instruments, chemical equipment, power tools, gardening tools and so on.
e.g.
Replacement of staple fiber PA6-GF30 with LFT PP-GF50
No water absorption, higher dimensional stability
No change in mechanical properties due to moisture absorption

Frequently asked questions
Q. Are there any special process requirements of long carbon fiber for the injection molding products?
A. We must consider the requirements of long carbon fiber for the injection molding machine screw nozzle, mold structure and injection molding process. Long carbon fiber is a relatively high cost material, and need to evaluate the cost performance problem in the selection process.
Q. What are the advantages of long carbon fiber materials?
A. The thermoplastic LFT long carbon fiber material has high rigidity, good impact strength, low warpage, low shrinkage, electrical conductively and electrostatic properties, and its mechanical properties are better than glass fiber series. Long carbon fiber has the characteristics of lighter and more convenient processing to replace metal products.
Q. The cost of long fiber products is higher. Does it has a high recycling value?
A. The thermoplastic LFT long fiber material can be recycled and reused very well.
