The carbon fiber composite material layer manufacturing method combines the carbon fiber composite material layer manufacturing tool to carry out the processes of gluing, layering, removing glue, leveling and the like of carbon fiber composite material layer manufacturing, wherein the rolling wheel mechanism 04 is used for carrying out rolling forming and vacuum pressure maintaining, so that the condition that resin glue is not distributed unevenly due to the gradient of the curved surface of the carbon fiber composite material layer can be avoided, and the carbon fiber composite material layer with excellent performance is manufactured.
The carbon fiber composite material layer is subjected to roll forming in the roll forming step, so that the surface of the carbon fiber composite material layer is smooth, and no obvious air bubbles exist. The surface of the carbon fiber composite material layer is smooth and free of air bubbles, the conditions of uneven quality and inconsistent performance of the formed carbon fiber composite material layer can be avoided, and the uniformity and the excellence of the quality of the carbon fiber composite material layer are guaranteed in the process.
The embodiment of the invention provides a specific implementation mode:
firstly, parameters of a curved surface, and the direction and the number of layers of the carbon fiber cloth are determined according to the carbon fiber composite material layer to be manufactured. The positions of the four height adjusters and the displacement adjusters are determined according to the parameters of the curved surface, the preparation work of laying is carried out after the setting is correct, the carbon fiber cloth with the proper size is cut, the resin adhesive is prepared according to the proportion, meanwhile, a layer of isolating membrane is laid on the plane layer 03, and the laying area is defined on the isolating membrane.
According to the process of manually pasting and spreading cloth, firstly, resin glue is coated on a spreading area defined on an isolation membrane, then, the steps of one layer of carbon fiber cloth and one layer of resin glue are repeated until the carbon fiber cloth with the set number of layers is spread, and finally, the isolation membrane is spread on the top layer. After the completion, the carbon fiber composite material layer is firstly subjected to degumming and leveling treatment by using a rubber scraping plate, redundant resin glue is scraped, and simultaneously, carbon fiber cloth is completely soaked to form a plane. At this time, the roller wheel mechanism 04 is used for performing the pull-back roll forming, but the carbon fiber composite material layer is compressed and formed, so that a flat bubble-free material layer is formed.
After the completion, the isolating films of the bottom layer and the top layer are connected and sealed, and vacuum suction pressure maintaining is carried out, so that the carbon fiber composite material layer is cured in a pressed state, and the surface unevenness of the carbon fiber composite material layer caused by the wrinkles of the isolating films is avoided in the vacuum suction process. The carbon fiber composite material layer is generally subjected to primary molding after curing for a certain time, and the finished carbon fiber composite material layer is obtained by removing the isolating membrane, polishing and processing.
The described embodiments are only some embodiments of the invention, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
