The geometrical and mechanical properties of three-dimensionally braided glass/epoxy
composite were investigated using the CAD system. The three-dimensional (3-D) yarn path
was described using third order spline curves referring to our previous work about the
circular braided preform. The CAD system for the flat plate-shaped composite was
developed by modifying that for the circular preform. The 3-D braided glass/ epoxy
composite was manufactured using the resin transfer molding (RTM) process and the
tensile modulus in the axial as well as transverse directions were measured. The tensile
modulus of the composite was predicted using the developed CAD system adopting the
volume averaging method. The prediction exhibited good agreement with the experimental
results. The effects of pitch length and the number of layers on the mechanical properties of
braided composite were successfully estimated using the CAD system.
