電着樹脂含浸法により作製したCFRPの電気的特性の評価

抄録

Carbon fiber reinforced plastics (CFRP) may be used as flat plate capacitors by inserting dielectrics between each layer. Composite materials that have both structural material and capacitor functions are called structural capacitors. The electrodeposition resin molding (EDRM) method is a method of electrochemically impregnating resin between carbon fibers, and ideally, the fibers are completely covered with resin. To investigate the possibility of using CFRP made by EDRM as a structural capacitor, impedance and capacitance were measured using an impedance analyzer. The cross section of the CFRP was observed using SEM to confirm the coating of the carbon fibers by the resin. As a result, it was found that it is possible to make a structural capacitor by inserting a CNF layer as a dielectric. The measured capacitance was consistent with values obtained in previous studies. However, the possibility of using the CFRP made by EDRM as a structural capacitor could not be confirmed due to the contact of the carbon fibers.
