유리섬유보강 폴리머 복합패널의 피로특성

초록

In this study, the fatigue properties of the GFRP composite panels of which core was made of the polymer mortar and both facings were reinforced by the high-tensile GFRP were surveyed. Composite-panel specimens consisted of polymer mortar core and GFRP compressive and tensile sides with various thickness were produced for an experimental study. Flexural fatigue tests were conducted to examine the correlation between the fatigue load and the fatigue life for various thickness of core and facings, and its results are presented. The correlation obtained in this study between the fatigue load and the fatigue life for various thickness are in good agreement with the modified Miner's law.
