변형속도에 따른 하이브리드 섬유보강 시멘트복합체의 인장거동

The purpose of this study was to evaluate the tensile behavior of hybrid fiber reinforced cement composite according to the strain rate. Experiment result, the tensile stress was improved by increase the strain rate. But polyvinyl alcohol was decrease the strain at peak stress, because of decrease number of multiple-crack and micro pull-out by increase the strain rate.
