Traditional forming processes of carbon-fiber reinforced thermoplastic composite profiles have many problems

such as the complex operation

low forming efficiency

high cost and incapability for mass production

which limit the large-scale applications of composites in the aerospace engineering. A new forming process is proposed

by the direct hotstamping of a fiber-reinforced composite panel using an instant heating deep-drawing die. Through the tensile tests of composite panels and hot stamping of the composite square-cup parts

the influences of fiber orientation on the stamping processing and fiber deformation within the specimens are studied

with the ultimate drawing depth and forming shear angle obtained. For better forming quality

it is suggested to adopt the parallel arrangement of the fiber orientation and the straight edge of the die for the hot stamping process of fiber-woven composite box parts.
