Abstract 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.
