Abstract
A method of forming a composite material part using an integrated shape memory polymer (SMP) and caul tool comprises the steps of: placing a caul on a positive feature of a mold, deforming the SMP from a relaxed state such that the SMP integrates with the caul to form an integrated SMP and caul tool, placing composite material on the integrated SMP and caul tool, heating the composite material to cure the composite material to form a composite material part while the SMP remains deformed, and stimulating the SMP to return to the relaxed state such that the SMP separates from the caul and the composite material part.
