Composite materials can very well inherit the performance advantages of several materials, making them have higher performance. Playing broken fiber materials can be said to be the representative of the entire composite material, and it is now applied to many industries. For better performance, the research and development of thermoplastic carbon fiber was carried out. What is this thermoplastic carbon fiber composite material? Many people may not understand thermoplasticity, so this article will tell you about it.
First look at the definition of thermoplastic
The thermoplasticity of the material actually means that the product undergoes reversible deformation or deformation after heating in the actual production, but the internal structure does not sound damaged or changed.
If it is heated, it will become soft, and the replastic process can be rapidly formed. Thermoplasticity means that when it is shaped, the original internal molecular chains are still in their original state, and the chemical and physical properties inside the material will not be damaged. My cousin, your polyether ketone polyphenylene sulfide is a thermoplastic carbon fiber material.
Thermoplastic Carbon Fiber Composites
By replacing the traditional epoxy resin base with a thermoplastic resin, the carbon fiber material is impregnated. Such a composite material belongs to the thermoplastic carbon fiber composite material, so the problem of impregnation must be mentioned here.
Broken fiber tow is a material similar to hair. This kind of carbon filament has anisotropy. A carbon filament is connected for the production of carbon fiber products.
Then here is to impregnate the thermoplastic resin on the carbon fiber tow, so that it can be completely impregnated, and then undergo a curing reaction to obtain a thermoplastic fiber-reinforced composite material. In this, it is the direction we need to focus on research and development, because thermoplastic When impregnating carbon fiber tow with resin, it cannot be completely impregnated, or if the impregnation is not complete, it will affect the performance of thermoplastic carbon fiber composite materials, such as strength, stiffness, toughness, durability and other aspects.
Therefore, the focus of domestic thermoplastic carbon fiber composite materials lies in who can take the lead in completing the mass production of long-fiber continuous silk thermoplastic broken fiber composite materials, which is the key to driving the market and breaking foreign technology blockades.
