Abstract

An integrated method for manufacturing a high-temperature resistant thin-walled component by preforming by laying a metal foil strip. The integrated manufacturing method includes: designing a preform, preparing a support die, determining a thickness of a foil strip, determining a width of the foil strip, developing a laying process, laying an A foil strip and a B foil strip, obtaining an AB laminated preform, bulging the preform, performing a reactive synthesis and a densification process of a bulged component, and performing a subsequent treatment of the thin-walled component. Various embodiments obtain an integral thin-walled preform with a complex structure, a uniform wall thickness and a shape close to the final part by continuously laying a metal foil strip with an appropriate width.
