Efficient Manufacturing Method of CFRP Corrugation by Using Electro-activated Deposition Resin Molding

摘要

CFRP corrugation structures are used for various purposes, and application tomorphing wing has recently been drawing attention. However, an effectivemanufacturing method for the CFRP corrugation has not established. Vacuum-assistedresin transfer molding (VARTM) method can decrease manufacturing cost, but itcannot be applied for corrugation since vacuum bagging is impossible. Therefore, theconventional method to laminate prepreg and consolidate by using autoclave has beenapplied. In this study, by using electro-activated deposition resin molding, it wasconfirmed that CFRP corrugation structures could be easily manufactured. Neitherautoclave nor vacuum bagging was necessary. The corrugation and corrugated coresandwiches with different pitches were fabricated and mechanical properties wereinvestigated.
