- Abstract
The engine hood cover should not only consider the structural strength, stiffness and stability, but also meet the service temperature and weight reduction requirements, so the high temperature bismaleimide resin matrix composite is selected to manufacture the engine hood cover. CCF800H/QY260E, a high-temperature cured bismaleimide high-strength carbon fiber prepreg, was used to prepare a large curvature and complex stiffened mouth cover by co-curing and secondary bonding process, which can serve for a long time at 230 °C. The molding technology of high temperature resin matrix composite parts, the method of laying closed ring reinforced edges and the positioning mode of stringer and reinforced edges with high efficiency and low cost were studied. The optimal selection of process auxiliary materials, tooling structure and materials, autoclave equipment and accessories for high temperature resin matrix composite parts was completed, and the high temperature resistant large curvature stiffened complex structure flap parts were successfully prepared.
