Composite material prop with mortise and tenon structure and preparation method thereof
The application belongs to the technical field of bullet carriers and relates to a preparation method of a composite material bullet carrier with a mortise and tenon structure. The structure of the bullet carrier is divided into a tooth shaft part and a saddle part. The tooth shaft part and the saddle part are connected by means of a mortise and tenon structure and a gluing mode. The back of the tooth shaft part is pre-prepared with a tenon structure, and the layers of the tooth shaft part adopt radial layers. The saddle part has a mortise structure matched with the tenon structure, and the two parts are then cured. The structure designed in the application can improve the phenomenon that the integral molding material sheet is easily naturally bent due to the uneven material thickness and the unbalanced gravity under the action of external pressure, the spare position is generated in the product interior or the outer surface, and the local material sheet is bent. The component molding can greatly enlarge the anti-deformation advantage of the narrow material sheet, improve the structural strength requirements of the bullet carrier shaft body windward curved surface, pressure bearing curved surface and non-equal thickness structure area, and reduce the layering process difficulty.
