Voided carbon fiber tapes comprising from 18K to 125K carbon fibers, a thermoplastic resin having a viscosity of about 10 to about 150 Pa•s, at least 3 void areas, a fiber fraction ranging from about 35 to 70 percent, a void volume ranging from about 2 to about 50 percent, and at least 10 percent wetted carbon fibers may be used to prepare consolidated thermoplastic composites which exhibit flexural strengths greater than or equal to 75 percent of the theoretical flexural strength.
