A Study on the Tensile Performance Change of Polyurea Waterproof Membrane Coat by Amount of Carbon Milled Fiber
탄소섬유길이 및 혼입량에 따른 폴리우레아 도막방수재의 인장성능 변화 연구
Abstract
Despite its excellent properties, polyurea coating waterproofing material is exposed to sunlight when it is applied to the exterior wall of concrete by exposed waterproofing method such as a roof of a building, resulting in a problem of causing a large deterioration in performance compared to initial properties. The purpose of this study is to investigate the effect of carbon fiber incorporation on the performance of carbon fiber - reinforced polyureas and to study the optimum carbon fiber length and content respectively. Result of the study confirmed that the performance of the carbon fiber was improved by 2% or more, and the carbon fiber length was 30 ㎛ and the mixing ratio was 3%. It is expected that stable durability can be secured when manufacturing fiber-incorporated polyureas.
