Carbon fiber plate is the carbon fiber arranged in the same direction using resin infiltration hardening to form carbon fiber plate, can effectively solve the problem of multi-layer carbon fiber distribution work difficulty and large amount of engineering, good reinforcement effect, convenient construction.

Carbon fiber plates are mostly made of carbon fiber composite prepregs. If you want to produce carbon fiber plates for composite needs, the raw materials should be selected well, and then the production process depends on it.

1. Cutting the prepreg: According to the requirements of the drawings, cut the carbon fiber prepreg into the appropriate length and width, usually the thickness of the prepreg is about 0.2mm, and then cut the corresponding amount of carbon fiber prepreg according to the thickness of the carbon fiber plate.
2. prepreg layering: the size is appropriate, the amount is appropriate, the next is the carbon fiber plate production process in one of the most important links, it is the layering. Prepregs need to be stacked in different directions so that the positive pressure in different directions remains the same. There are usually 0°, ±30°, ±45° and 90° to choose from, and the layup is usually carried out in the way of mixed layup.
3. high temperature curing molding: carbon fiber prepreg layer is finished, just have the prototype of carbon fiber plate, but also need to put it into the autoclave high temperature curing molding, this time the carbon fiber plate has been basically shaped. Different materials of carbon fiber prepreg need to choose different temperature, pressure and time.
4. Grinding treatment: Take out the carbon fiber plate from the autoclast, cut the excess part of the edge, polish the surface, remove impurities and dirt, and keep the surface smooth and clean.

Carbon fiber plate after curing, in order to precision requirements or assembly needs, it still need to be cutting, drilling and other post-processing. In the same cutting process parameters, cutting depth and other conditions, the selection of different materials, size, shape of the cutting tool and drilling tool, the effect is very different, at the same time, the strength of the cutting tool and drilling tool, direction, time and temperature and other factors will also affect the processing results.

In the process of post-machining, try to choose the sharp tool with diamond coating and the drill bit with integral hard alloy.    The wear resistance of the tool and the drill itself determines the quality of machining and the service life of the tool.    If the cutting tool and drill are not sharp enough or used improperly, it will not only accelerate the wear and increase the processing cost of the product, but also cause damage to the board, affecting the shape and size of the board and the stability of the size of the holes and slots on the board.    In serious cases, it will cause lamellar tearing of the material or even block collapse, leading to the scrapping of the whole board.

When drilling carbon fiber sheets, we need make the speed as faster as we can.    In terms of bit selection, the PCD8 bit's unique tip design is suitable for carbon fiber sheet and can penetrate carbon fiber sheet better, reducing the risk of delamination.

When cutting the thick carbon fiber sheet, it is recommended to use the left and right spiral edge design of double-edge compression milling cutter, the sharp cutting edge has the upper and lower spiral tip at the same time, the cutting balance tool up and down axial force, to ensure that the cutting force is directed to the inside of the material, to obtain stable cutting conditions, can inhibit the material stratification phenomenon.
