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 Related materials                        PA6-LCF                                    PPA-LCF                                    TPU-LCF Frequently asked questions Q.

PBT materials Polybutylene terephthalate (PBT) is a thermoplastic polyester and one of the top five engineering plastics. PBT has excellent overall performance, is one of the toughest engineering plastics, and has high dimensional stability, good chemical resistance, excellent electrical insulation, good mechanical properties and elasticity, low water absorption, etc. PBT filling Long glass fiber compounds PBT (polybutylene terephthalate) is a polyester-based plastic, while glass fiber is a reinforcing material that is usually added to plastics in fiber form to enhance their mechanical properties. When PBT is combined with glass fibers, the following effects occur: 1. Enhanced strength and stiffness: glass fiber has excellent strength and stiffness, and adding it to PBT can significantly increase the mechanical properties of the plastic. This makes the material of PBT with glass fiber more strong and rigid when it is subjected to force or stress, and less likely to deform or break. 2. Improve heat resistance: glass fiber has a high melting point and good heat resistance performance. When glass fiber is added to PBT, it can improve the heat resistance of PBT, so that it can keep better performance at higher temperature and prevent softening or melting. 3. Improve corrosion resistance: Glass fiber has excellent corrosion resistance, and adding it to PBT can improve its resistance to chemicals, solvents and other corrosive media. This makes PBT with glass fiber have longer service life in some special environments. 4. Improve insulation performance: PBT itself has good insulation performance, and the addition of glass fiber further improves the insulation performance of PBT material. This makes the PBT with glass fiber more suitable for electrical and electronic applications, which can effectively isolate the current and reduce leakage and electromagnetic interference. All in all, PBT with glass fiber can enhance the mechanical properties, heat resistance, corrosion resistance and insulation properties of plastics, making them more widely used in various applications. However, the performance of the material may vary depending on the specific glass fiber content and the addition process.

What is PA6 plastic? polyamide (PA), usually called Nylon, is a hetero-chain polymer containing amide group (-NHCo -) in the main chain. It can be divided into aliphatic group and aromatic group. It is the earliest developed and the most used thermoplastic engineering material. Polyamide main chain contains many repeated amide group, used as a plastic called nylon, used as a synthetic fiber called nylon. A variety of different polyamides can be prepared according to the number of carbon atoms contained in binary amines and dibasic acids or amino acids. At present, there are dozens of polyamides, among which polyamide-6, polyamide-66 and polyamide-610 are the most widely used. Polyamide-6 is an aliphatic polyamide, with light weight, strong strength, wear resistance, weak acid and alkali resistance and some organic solvents, easy molding and processing and other excellent properties, widely used in fiber, engineering plastics and thin films and other fields, but PA6 molecular chain segment contains strong polarity amide groups, easy to form hydrogen bonds with water molecules, The product has the disadvantages of large water absorption, poor dimensional stability, low impact strength in dry state and low temperature, strong acid and alkali resistance. Advantages of nylon 6: High mechanical strength, good toughness, high tensile and compressive strength. Outstanding fatigue resistance, the parts after repeated bending can still maintain the original mechanical strength. High softening point, heat resistant. Smooth surface, small friction coefficient, wear-resistant. Corrosion resistance, very resistant to alkali and most salts, also resistant to weak acids, oil, gasoline, aromatic compounds and general solvents, aromatic compounds are inert, but not resistant to strong acids and oxidants. It can resist the corrosion of gasoline, oil, fat, alcohol, alkaline and so on, and has good anti-aging ability. It is self-extinguishing, non-toxic, odorless, good weather resistance, inert to biological erosion, and has good antibacterial and mildew resistance. Has excellent electrical performance, good electrical insulation, nylon volume resistance is high, high breakdown voltage resistance, in dry environment, can work frequency insulation material, even in high humidity environment still has good electrical insulation. Light weight, easy dyeing, easy forming, because of low melting viscosity, can flow quickly. Disadvantages of Nylon 6: Easy to absorb water, water absorption, saturated water can reach more than 3%. Poor light resistance, in the long-term high temperature environment will oxidize with oxygen in the air, the color turns brown at the beginning, and the subsequent surface is broken and cracked. Injection molding technology requirements more strict, the existence of trace moisture will cause great damage to the quality of molding; The dimensional stability of the product is difficult to control because of thermal expansion. The existence of sharp Angle in the product will lead to stress concentration and reduce the mechanical strength; If the wall thickness is not uniform, it will lead to the distortion and deformation of the parts. High precision of equipment is required in post-processing. Will absorb water, alcohol and swelling, not resistant to strong acid and oxidant, can not be used as acid-resistant materials. Why filling Long Glass Fiber? PA6 has excellent properties such as light weight, strong strength, abrasion resistance, weak acid and alkali resistance and some organic solvents, and easy molding and processing. It is widely used in the fields of fibers, engineering plastics and films. However, the molecular chain segment of PA6 contains highly polar amide groups, which are easy to form hydrogen bonds with water molecules. The product has the disadvantages of large water absorption, poor dimensional stability, low impact strength in dry state and low temperature, strong acid and alkali resistance. With the development of science and technology and the improvement of life quality, the defects in some properties of traditional PA6 materials have limited its development in some fields. In order to improve the performance of PA6 and expand its application field, PA6 should be modified. Filling enhancement modification is a common method for physical modification of PA6. It refers to the modification of PA6 by adding fillers such as glass fiber and carbon fiber into the matrix to significantly improve the mechanical properties, flame retardant properties, thermal conductivity and dimensional stability of the material. What is application of PA6-LGF? Modified section of 30% long glass fiber reinforced PA6 is the ideal material for processing power tool shell, power tool parts, engineering machinery parts and automobile parts. Its mechanical properties, dimensional stability, heat resistance and aging resistance have been significantly improved. The fatigue resistance strength is 2.5 times that of unenha...

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.
