摘要
Methods of forming a molded composite material are generally provided. A composite forming precursor (e.g., fibers and/or a resin material) can be applied onto a mold that includes a plurality of piezoelectric sensors embedded into the mold. The composite forming precursor can then be cured adjacent to the mold to form a molded composite material. During curing, the molded composite material can be monitored, using the piezoelectric sensors to detect any defects formed during curing.
