VaRTM法を用いたGFRTPサンドイッチ材の成形と力学特性評価

抄録

FRP sandwitch structure is used in aerospace and automotive industries because of it has high specific bending modulus and strength. In this study, a GFRTP sandwich panel using in situ polymerization polyamide 6 (in situ PA6) as metrix was fabricated by VaRTM method. In order to confirm its mechanical properties, three-point bending and impact tests were carrid out. As a result, the bending strength and specific energy absorption capability of the GFRTP sandwich were almost same values of the GFRP sandwitch using epoxy resin as materix.
