In terms of performance, the performance of carbon fiber board is lower than that of carbon fiber cloth, and both of them are lower than the strength of carbon fiber raw materials, which will make many people unable to understand. Recently, Xiaobian was asked such a question when he was consulted. What is the reason?
Carbon fiber board and carbon fiber cloth are both products of carbon fiber composite materials, so what we call fiber cloth is just like a layer of cloth used in spinning, which is the same as carbon fiber prepreg, that is, the products cured and formed after carbon fiber prepreg is laid layer by layer. There must also be a process in which carbon is first laid and then impregnated with resin. Then in the actual test, it will be found that the strength of carbon fiber board is not as good as that of precursor and carbon fiber cloth. But this happens on thinner carbon fiber boards.
Both carbon fiber board and carbon fiber cloth can be used for reinforcement. On the same strength, the tensile strength of carbon fiber board is 2400 MPa, that of carbon fiber cloth is 3400 MPa, and that of carbon fiber raw material T300 is 5000 MPa. Therefore, the strength of carbon fiber board is lower than that of carbon fiber cloth, The T300 carbon fiber strength of carbon fiber material can reach 5000 MPa, so the strength of carbon fiber board is lower than that of carbon fiber cloth.
Carbon fiber cloth is made of carbon fiber precursor and resin, which makes many carbon fiber bundles into a whole process. But just because the performance of resin is much lower than that of carbon fiber precursor, if there are too many carbon fiber bundles, it will lead to cracking and delamination of carbon fiber board in molding, so the strength of very thin carbon fiber board is not as unreasonable as carbon fiber cloth.
But the thickness of carbon fiber board can be made, so the actual reinforcement effect is much higher than that of carbon fiber board, because carbon fiber board is because carbon fiber board belongs to composite section. How to form a better composite section and improve the joint stress of the two is also a problem to be solved for high-strength carbon fiber board.
Therefore, the strength of carbon fiber board is lower than that of carbon fiber cloth, which has something to do with the content of carbon fiber inside. In order to better improve the strength of carbon fiber board in the production of carbon fiber board, it is necessary to carry out ply design and better obtain performance advantages, so the strength of carbon fiber board is also improved, including the assembly demand in many industrial product assembly, Including the use of many processing parts, the advantage of carbon fiber board is more obvious.
