Introduction of Nylon66 filled LCF pellets

PA66 is a high-performance engineering plastics, moisture absorption, poor dimensional stability of products, strength and hardness and metal.

In order to overcome these shortcomings, as early as the 1970s, people use carbon fiber and glass fiber to enhance to improve its performance.

PA66 reinforced with carbon fiber fiber materials in recent years the development of faster, because PA66 and carbon fiber are excellent performance in the field of engineering plastics materials, the composite material comprehensive embodiment of the superiority of the two, such as strength and rigidity than the unenhanced PA66 is much higher than that of the high-temperature creep is small, the thermal stability of a significant improvement in the dimensional accuracy of the good, wear-resistant.

At present, PA66 carbon fiber composite materials are mainly short-cut or long carbon fiber reinforced particles, has been widely used in the automotive industry, sporting goods, textile machinery, aerospace materials and other fields.

Carbon fiber is lightweight, high tensile strength, abrasion resistance, corrosion resistance, creep resistance, electrical conductivity, heat transfer, etc. It is very similar to glass fiber, but superior to glass fiber. Compared with glass fiber, the modulus is 3 times higher, which is a material with high rigidity and high strength.

Datasheet of PA6-LCF for reference

From the experiments of the technical department, we know that the bending strength, bending modulus of elasticity, impact strength and plane shear strength of the carbon fiber PA66 fiber-added material increase with the increase of carbon fiber content, transverse shear strength slightly decreased, overall the strength of the material has increased dramatically.

Q & A

1. Is there a unified reference data for carbon fiber product performance?

The performance of specific carbon fiber filaments is fixed, such as Toray's carbon fiber filaments, T300, T300J, T400, T700 and so on, there are a series of parameters can be traced. However, there is no uniform standard to measure the carbon fiber composite products. Firstly, the different types of raw materials selected will lead to different performance of the products, and then due to the choice of matrix and the different design of the products, it will lead to different performance of the products. In addition to some common carbon fiber tubes, carbon fiber boards and other conventional parts, most of the carbon fiber products in the production of the sample before the test to determine whether the performance of the product is in line with the use of the expected standard, and as a base point, so as to carry out the production and use of large quantities.


2. Are carbon fiber composite products expensive?

The price of carbon fiber composite products is closely related to the price of raw materials, the level of technology and the quantity of products. Some products of the industrial environment requirements are high, the performance of carbon fiber products and materials have special requirements, which requires the selection of specific raw materials, raw materials, the higher the performance of the natural price of the more expensive, such as the application of orthopedic carbon fiber PEEK thermoplastic materials. Of course, the more complex the production process, the greater the working time and workload, and the production cost increases. However, the larger the order quantity, the lower the cost per piece, once the mass production of a particular carbon fiber product has been established. In the long run, the superior performance of carbon fiber will prolong the service life of the product, reduce the number of maintenance, and is also very beneficial to the reduction of the cost of use.


3. Are carbon fiber composite products toxic?

Carbon fiber composites are made of carbon fiber filaments mixed with ceramics, resins, metals and other matrices, generally not toxic. For example, the above mentioned PEEK material is a food grade resin, this material has good compatibility with the human body, not only harmless to the human body, but also because of the high strength, modulus of elasticity close to the bone cortex and other reasons to become a more ideal material for bone surgery. Carbon fiber medical bed board, every day will be in contact with many patients' body, will not have adverse effects on the human body, on the contrary, for the accuracy of medical diagnosis there is a great help.


4. What is the difference between thermoset carbon fiber composites and thermoplastic carbon fiber composites?

Thermoset carbon fiber composites favor the role of curing agent in curing molding. Thermoplastic carbon fiber composite products mainly rely on cooling down to achieve the shape. Thermoplastic carbon fiber composites are not as popular as thermoset carbon fiber composites, mainly because of the high price, generally used in high-end industries. Thermosetting carbon fiber composites due to the limitations of the resin matrix itself, the difficulty of recycling, generally not considered; thermoplastic carbon fiber composites can be recycled, as long as the heating to a certain temperature can be secondary production.
