Fiber deformation behavior during press forming of rectangle cup by using plane weave carbon fiber reinforced thermoplastic sheet

摘要

Press forming of a carbon fiber reinforced thermoplastic sheet with consolidated thermoplastic resin was studied. The carbon fibers deform during the press forming of a flat plane weave sheet to a rectangle cup. The fabric deformation depends on the relationship between the direction of fibers and that of the die corners. The difference in the deformation is attributed to the deformation availability of the woven carbon fiber. The deformation behavior in the forming should be considered in the design of die profiles, die clearance, and the requirements for the mechanical properties of the formed product.
