Abstract

This study investigated experimentally the tensile behavior of polyetylene fiber-reinforced cementless composite. Four types of polyetylene fiber-reinforced cementless composite were designed. The water to binder ratio was 0.30-0.38, and the amount of polyetylene fiber was 1.75 vol%. A series of experiments including uniaxial tension, density, and compression tests were performed to evaluate the performance of the composites. From the test results, it was exhibited that the composite has superior tensile performance such as high tensile strength and tensile strain capacity compared with other types of composites.

본 연구의 목적은 폴리에틸렌섬유로 보강한 무시멘트 복합재료의 인장 거동을 실험적으로 조사하는 것이다. 폴리에틸렌섬유 보강 무시멘트 복합재료의 성능을 평가하기 위하여 4가지 배합을 결정하였다. 물/결합재비는 0.30에서 0.38이며, 폴리에틸렌섬유의 혼입량은 부피비로 1.75 %이다. 일축 인장 실험, 밀도 실험, 압축강도 실험 등 일련의 실험을 수행하였으며, 실험결과 본 연구에서 조사한 폴리에틸렌섬유 보강 무시멘트 복합재료는 기존 복합재료에 비하여 높은 인장강도와 높은 연성 등 전반적으로 우수한 인장 성능을 나타내었다.
