In the application of the entire material field, in order to better obtain high-performance products, the performance of the material will be improved at this time. The same is true in the field of carbon fiber composite materials, where thermoplastic resins replace traditional thermosetting resins. What are the advantages and disadvantages of this thermoplastic carbon fiber, and what is the molding process.
Advantages and disadvantages of thermoplastic carbon fiber
There are actually many performance advantages of thermoplastic carbon fiber, mainly related to thermoplastic resin. The outstanding performance here is also the common performance of thermoplastic resin and carbon fiber tow.
It has very good impact resistance performance, thermoplastic resin itself has very good impact resistance performance, and carbon fiber tow as a reinforcement can also provide very good impact resistance effect
Therefore, the overall impact resistance is very good.
It has a very good room temperature storage performance advantage. Like traditional thermal carbon fiber, it needs to be stored at low temperature, so most of our carbon fiber product manufacturers have cold storage for storage, and thermoplastic carbon fiber materials do not have such a big requirement. There is no need to worry about chemical reactions, and it also makes transportation easier.
The use advantage of high yew, most of today’s thermoplastic carbon fiber composite materials are applied in the field of aerospace, in the actual test of aerospace products, it shows a very high toughness advantage, because the internal carbon fiber Under the structure, after the thermoplastic resin is bonded, in the case of external cracks, the internal cracks will not extend and will not spread to better ensure safety.
The performance of recyclable remolding is also a particularly good performance of thermoplastic carbon fiber materials, which can make the thermoplastic resin inside the thermoplastic carbon fiber products not undergo chemical changes
It can be cooled and heated to affect the entire material properties
Yes, it can be re-formed by slicing.
The overall high temperature resistance is also better, because the overall high temperature resistance of thermoplastic resin itself is relatively high, which also makes the overall high temperature resistance of thermoplastic carbon fiber better, and can be applied to more industries.
The disadvantage is that the price is expensive. Although thermoplastic puncture fibers have more advantages in molding efficiency, because the price of thermoplastic resin fingers is relatively high, the price of your PEK is relatively expensive, and the price of carbon fiber itself is also relatively high. , then this causes the overall unit price of thermoplastic carbon fiber composite materials to be relatively high, combined with the effect of molding, the entire product price will be higher, but the performance is better.
Forming of thermoplastic carbon fibers
The molding of thermoplastic carbon fiber materials is similar to our traditional thermosetting carbon fiber materials, both of which can be thermoformed, especially our long-fiber continuous thermoplastic carbon fiber composite products with outstanding performance, so the molding of thermoplastic defiber at this stage is still thermal Shape more.
That is through the mold. The mold usually uses a male and female mold, and then the thermoplastic carbon fiber composite material is laid inside. After the mold is sealed, it is heated first, and then the resin is melted and flowed. After cooling, demould to obtain the required thermoplastic carbon fiber product.
