Product Detail

Thermoplastic prepreg tape composites


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.

Carbon Fiber Reinforced Plastic Carbon fiber reinforced plastic composite (CFRP) is a lightweight, strong material that can be used to make a wide range of products used in everyday life. It is a term used to describe fiber reinforced composites with carbon fiber as the main structural component. Note that the "P" in CFRP can also stand for "plastic" rather than "polymer." Typically, CFRP composites use thermosetting resins such as epoxy, polyester, or vinyl esters. Despite the use of thermoplastic resins in CFRP composites, "carbon fiber reinforced thermoplastic composites" often uses its own acronym, CFRTP composites. LFT-G focuses on LFT&LFRT. Long Glass Fiber Series (LGF) & Long Carbon Fiber Series. Compared with Short Carbon Fiber, Long Carbon Fiber has more excellent performance in mechanical properties. It is  more suitable for large products and structural parts. It has 1-3 times higher (toughness) than Short Carbon Fiber, and the tensile strength(strength and rigidity) is increased by 0.5-1 times. Properties of CFRP composites Composites reinforced with carbon fiber are different from other FRP composites that use traditional materials such as glass fiber or arylon fiber. Advantages of CFRP composites include: Light weight: Conventional fiberglass reinforced composites using continuous fiberglass and 70% fiberglass (glass weight/gross weight) typically have a density of 0.065 lb/cubic inch. A CFRP composite with the same 70% fiber weight might typically have a density of 0.055 lb/cubic inch. Increased strength: Carbon fiber composites not only weigh less, but CFRP composites are stronger and stiffer per unit weight. This is true when comparing carbon fiber composites to glass fibers, and even more so when comparing metals. For example, when comparing steel to CFRP composites, a good rule of thumb is that a carbon fiber structure of the same strength typically weighs 1/5 as steel. You can imagine why car companies are looking into using carbon fiber instead of steel. When comparing CFRP composites to aluminum (one of the lightest metals used), the standard assumption is that an aluminum structure of the same strength might weigh 1.5 times as much as a carbon fiber structure. Of course, there are many variables that can change this comparison. Grades and qualities of materials may vary, and for composites, the manufacturing process, fiber structure and quality need to be considered. Disadvantages of CFRP composites Cost: As amazing as the material is, there's a reason carbon fiber can't be used in every situation. Currently, the cost of CFRP composites is too high in many cases. Depending on current market conditions (supply and demand), the type of carbon fiber (aerospace grade versus commercial grade), and bundle size, carbon fiber prices can vary significantly. On a per-pound basis, carbon fiber can cost anywhere from five to 25 times more than fiberglass. The difference is even greater when comparing steel with CFRP composites. Electrical conductivity: This can be a plus or minus for carbon fiber composites, depending on the application. Carbon fiber is extremely conductive, while glass fiber is insulating. Many applications use fiberglass instead of carbon fiber or metal, strictly because of electrical conductivity. For example, in the utility industry, many products require the use of fiberglass. This is one of the reasons why the ladder uses fiberglass as the ladder rail. The chance of electric shock is much lower if the fiberglass ladder comes into contact with the power cord. The situation with CFRP ladders is different. Although the cost of CFRP composites remains high, new technological advances in manufacturing are continuing to provide more cost effective products. Application of PP-LCF Long Carbon Fiber as the reinforcement material of CFRP, its proportion is only 1/4 of iron, specific strength is 10 times that of iron, elastic modulus is 7 times that of iron, carbon fiber excellent physical properties are played in various fields from sports goods to aircraft.

PP material PP is a polymer made of propylene as monomer by coordination polymerization, and is one of the five major general-purpose plastics PE, PP, PVC, PS and ABS. 1. colorless, tasteless, five toxic, unadded PP material compounded with FDA and other food-grade material requirements; 2. due to the crystalline nature of PP, the original color milky white translucent, better transparency than PE; 3. low specific gravity of 0.9, almost one of the lightest plastics than water; 4. good toughness, especially repeated resistance to bending ability, commonly known as 100 fold rubber; 5. better heat resistance than PE, which can reach up to 120°C; 6. good resistance to hydrolysis and can be sterilized by high temperature steam 7. good chemical resistance, especially acid resistance, can be due to the storage of concentrated sulfuric acid containers; 8. outdoor use is susceptible to light, ultraviolet light and other aging. Modified PP material PP material by filling carbon fiber can increase the rigidity and modulus of PP material, reduce the material deformation caused by shrinkage, but at the same time the material toughness decreases. By adding anti-UV agent, anti-aging agent can improve the outdoor use performance of PP, and adding flame retardant material can improve the flame retardant performance of PP.
