The Behavior of Crack Growth Rate for APAL and CPAL Patched with FRP Laminate in Aluminum Alloy Plate
알루미늄 합금판재에 FRP 라미네이터를 보강한 APAL 및 CPAL 재의 균열전파속도 거동
Abstract
A hybrid composite (APAL;Aramid Patched ALuminum alloy, CPAL;Carbon Patched ALluminum alloy), consisting of a Al 2024-T3 aluminum alloy plate sandwiched between two aramid/epoxy and carbon/epoxy laminate, was developed. Fatigue crack growth behavior was examined at stress ratios of R=0.2, 0.5. The APAL and CPAL showed superior fatigue crack growth resistance, which may be attributed to the crack bridging effect imposed by the intact fibers in the crack wake.
