Description

A process for manufacturing special-shaped products with carbon fiber synthetic resin

technical field

The invention relates to the field of aviation, in particular to a process for manufacturing special-shaped products with carbon fiber synthetic resin.

Background technique

With the rapid development of my country's aviation industry, the product requirements of the aviation industry are getting higher and higher. Therefore, new processes and new technologies are constantly being applied, and detection technology also puts forward higher requirements, which require more accurate and efficient detection. For aircraft engine-related data, the existing detection sections are all made of metal materials.

The air intake connection section of the aircraft engine is made of metal material, but because the metal material is too strongly affected by the temperature, the temperature is too affected by the material, resulting in a decrease in measurement accuracy. The difficulty is high, which will affect the quality and effect of aviation industry product processing, and affect the normal use function of aviation industry products. In the process of product processing, and in the traditional product processing technology, the die-casting device is used to process the mold according to the shape of the product. The final product is processed through the processed mold. In this way, the mold is processed by the die-casting device. For some special-shaped products, the processing process is very complicated, time-consuming and labor-intensive, and consumes processing costs.

The key to the operation of the polishing machine equipment is to try to get the maximum polishing rate, so as to quickly Remove the damaged layer produced during polishing. At the same time, it is necessary to ensure that the polishing damage layer will not affect the final observed tissue, that is, it will not cause false tissue. The former requires the use of coarser abrasives to ensure a greater polishing rate to remove the polished damage layer, but the polishing damage layer is also deeper; the latter requires the use of the finest materials to make the polishing damage layer shallower, but the polishing damage layer is deeper. The rate is low.

Furthermore, the product molding process is to use 3D printing equipment to process products as internal and external cavity molds to ensure that the processed product molds fit together to form the final product that needs to be processed. The present invention uses new technology first material 3D printing technology Guarantee the processing of special-shaped product molds, avoid the difficulty of traditional equipment processing, reduce the processing cost of equipment, and use carbon fiber resin synthesis technology to replace the original metal materials for aircraft engine detection section materials to more accurately detect the required relevant data , because the thermal conductivity of carbon fiber resin synthetic materials is much worse than that of metal materials, it is relatively less affected by temperature, the detection conditions are much better, and the efficiency is higher, which improves the quality and effect of aviation industry product processing and ensures aviation industry normal use of the product.

Furthermore, the product processing in S2 is to set resin primer on the inner membrane, spread carbon fiber cloth on the primer, and repeat the operation to make the product reach the thickness of the drawing equipment, and after reaching the preliminary product specifications, add resin, and the inner and outer The cavity membrane closes and waits to cure, forming the preliminary product.

Furthermore, the removal of the product in S3 is to wait for the preliminary product to solidify and exit the mold, and to polish the preliminary product to remove defects, so that the product meets the requirements of the drawing and form the final product, and the processing of the product is completed.
