PEEK-Long carbon fiber Polyetheretherketone (PEEK), the complete English name for polyetheretherketone, is a specialty engineering plastic with excellent performance, and has more advantages than other specialty engineering plastics, such as wear resistance, high temperature resistance, high strength and high modulus, flame retardant and radiation resistant, and so on. In addition polyetheretherketone (PEEK) has good thermal stability and melt flow above the melting point, so polyetheretherketone (PEEK) also has the typical processing properties of thermoplastics. PEEK resin is nontoxic, lightweight, corrosion-resistant, and one of the closest materials to the human skeleton, which is well compatible with the musculature, so it is often used instead of metal to make human bones. Carbon fiber-reinforced PEEK composites make up for the weaknesses of toughness and deviations in impact strength. Carbon fiber-reinforced PEEK composites can exhibit high mechanical strength and hydrolytic stability under conditions such as hot water, steam, solvents, and chemical reagents, and can be used to prepare various medical devices that require high-temperature steam sterilization. Advantages of PEEK-LCF PEEK has high rigidity, good dimensional stability, low coefficient of linear expansion, and can withstand great stress without significant elongation over time, and its low density and good processing properties make it suitable for parts with high requirements for fineness. Among these elements, carbon fiber materials overlap highly with the characteristics of PEEK. Carbon fiber is not only one of the typical lightweight materials, it is also outstanding in terms of mechanical properties. As a result, carbon fiber reinforced PEEK composites can reduce weight by at least 70% compared to traditional metal materials. PEEK material itself is very wear-resistant, and good interface bonding with carbon fibers to further enhance its wear resistance, through the carbon fiber reinforced PEEK composite parts and cobalt alloy materials for wear comparison experiments, the results show that: at 23 ℃, using the M-200 wear machine at 400 rpm after 100 minutes of wear, found that the carbon fiber reinforced PEEK composite surface smooth The wear marks were small, and the carbon fiber bonded well with PEEK without fiber extraction. In contrast, the cobalt alloy surface wear marks are very obvious, even a large number of wear particles appear, the metal internal impurities image visible. PEEK exhibits high mechanical strength and hydrolytic stability in hot water, steam, solvents and chemical reagents, etc. Datasheet for reference PEEK-LCF application Q&A 1. What are the types of thermoplastic carbon fiber composites? Carbon fiber thermoplastic composites are composites with carbon fiber as the reinforcing material and thermoplastic resin as the matrix. From the reinforcement method of carbon fiber, it can be divided into long-cut carbon fiber (LCF) reinforced thermoplastic composites, short-cut carbon fiber (SCF) reinforced thermoplastic composites and continuous carbon fiber (CCF) reinforced thermoplastic composites. Long-cut carbon fiber and short-cut carbon fiber mainly refer to the application length of carbon fiber materials, there is no strict fixed distinction between the two, generally between a few millimeters to a few centimeters, the more common specifications are 6mm, 12mm, 20mm, 30mm, 50mm. Carbon fiber thermoplastic composites can also be classified according to the thermoplastic resin. There are many common thermoplastic resins, such as PE, PP, PVC, etc. However, thermoplastic resin composites with carbon fiber reinforcement are mostly used in aerospace, precision equipment and other demanding working environments, therefore, carbon fiber thermoplastic composites are more often made of polyether ether ketone (PEEK), PPS, polyimide ( PI), polyetherimide (PAI) and other mid- to high-end thermoplastic resins as the matrix to achieve the optimization of material performance. 2. How does thermoplastic carbon fiber composite material achieve low cost and environmental protection? Thermoplastic carbon fiber composites are used to make parts for high-end machinery. They have excellent machinability, vacuum forming, stamping mold plasticity, and bending processability. For example, Teijin has been able to add a recycling process to the process according to specific needs, and to shred and mold the corners of thermoplastic carbon fiber composite materials after stamping to make recycled materials for making small products or for molding nuts and studs on carbon fiber prototypes. This method can greatly reduce the loss of raw materials, improve the efficiency of the use of thermoplastic carbon fiber composite materials, reduce the overall cost, and thus achieve the purpose of environmental protection. In addition, thermoplastic carbon fiber composites can reduce the molding cycle time compared with thermoset carbon fiber composi...

PA6 material PA6 is one of the most widely used materials in the current field, and PA6 is a very good engineering plastic with balanced and good performance. The raw materials for the manufacture of nylon 6 engineering plastic are extensive and inexpensive, and it is not restricted by the technological monopoly of foreign companies. However, in order to make good use of this inexpensive and excellent material, we must first understand it. Today, we will start with glass fiber reinforced PA6 engineering plastics, because it is the most important category of PA6 engineering plastics. Just like any other engineering plastics, PA6 has advantages and disadvantages, such as high water absorption, low temperature impact toughness and dimensional stability is relatively poor. So engineers will use different methods to make PA6 better, which we call modification. At present, the most common method is to blend and modify PA6 with glass fiber (GF). Today, we will take a look at the mechanical properties of PA6 engineering plastics under the glass fiber GF system for reference and help us select materials. PA6-LGF 1. Influence of glass fiber content on PA6 engineering plastics We can find from the application and experiment that the content index is often one of the biggest influencing factors in fiber reinforced composites. As the glass fiber content increases, the number of glass fibers per unit area of the material will increase, which means that the PA6 matrix between the glass fibers will become thinner. This change determines the impact toughness, tensile strength, bending strength and other mechanical properties of glass fiber reinforced PA6 composites. In terms of impact performance, the increase of glass fiber content will greatly increase the notch impact strength of PA6. Taking long glass fiber (LGF) filling PA6 as an example, when the filling volume increases to 35%, the notch impact strength will increase from 24.8J/m to 128.5J/m. But the glass fiber content is not more is better, short glass fiber (SGF) filling volume reached 42%, the impact strength of the material reached the highest 17.4kJ/㎡, but continue to add will let the gap impact strength showed a downward trend. In terms of bending strength, the increase of the amount of glass fiber will make the bending stress can be transferred between the glass fiber through the resin layer; At the same time, when the glass fiber is extracted from the resin or broken, it will absorb a lot of energy, thus improving the bending strength of the material. The above theory is verified by experiments. The data show that the bending elastic modulus increases to 4.99GPa when the LGF (long glass fiber) is filled to 35%. When the content of SGF (short glass fiber) is 42%, the bending elastic modulus reaches 10410MPa, which is about 5 times that of pure PA6. 2. Influence of glass fiber retention length on PA6 composites The fiber length of the glass fiber also has an obvious effect on the mechanical properties of the material. When the length of the glass fiber is less than the critical length (the length of the fiber when the material has the tensile strength of the fiber), the interface binding area of the glass fiber and the resin increases with the increase of the length of the glass fiber. When the composite material is broken, the resistance of the glass fiber from the resin is also greater, so as to improve the ability to withstand the tensile load. When the length of glass fiber exceeds the critical, the longer glass fiber can absorb more impact energy under impact load. In addition, the end of the glass fiber is the initiation point of crack growth, and the number of long glass fiber ends is relatively less, and the impact strength can be significantly improved. The experimental results show that the tensile strength of the material increases from 154.8MPa to 164.4MPa when the glass fiber content is kept at 40% and the length of the glass fiber increases from 4mm to 13mm. The bending strength and notched impact strength increased by 24% and 28%, respectively. Moreover, the research shows that when the original length of the glass fiber is less than 7mm, the material performance increases more obviously. Compared with short glass fiber, long glass fiber reinforced PA6 material has better appearance warping resistance, and can better maintain mechanical properties under high temperature and humidity conditions. TDS for your reference PA6 can be made into long glass fiber reinforced material by adding 20%-60% long glass fiber according to the characteristics of the product. PA6 with long glass fiber added has better strength, heat resistance, impact resistance, dimensional stability and warping resistance than without glass fiber added. Following TDS show the data of PA6-LGF30. Application PA6-LGF has the largest proportion of applications in the automotive industry, by electronic and electrical applications, and also involving machinery and engineering ...
