초록
복합재의 고강성을 얻기 위하여 매트릭스 및 섬유 각각의 물성도 중요하지만, 매트릭스와 섬유간 계면접착력이 매우 중요하다. 바닷물이 계면을 침투하게 되면 계면물성이 낮아지게 되고, 복합재의 균열이 일어나게 될것이다. 이번 실험에서, 물리적/계면 시험법과 미세역학 시험법을 이용하여 유리섬유 노화일수에 따른 계면물성변화를 연구하였다. 유리섬유의 기계적 물성변화는 단섬유 인장시험을 통해 조사했다. 유리섬유의 계면물성 변화는 비파괴 음향방출과 피로시험을 응용한 미세역학 시험을 통해 조사했다. 피로강도의 변화를 통하여 유리섬유와에폭시간의 상대적인 계면물성을 평가하였다. 실험결과, 염수노화 일수에 따라 유리섬유의 직경이 감소하는 것을관찰하였고, 미처리의 경우보다 기계적 및 계면 물성 감소를 나타내었다.
Abstract
Although it is important to have high strength of each of fiber and matrix, interface between fiber andmatrix is most important. If NaCl water penetrates the interface, that area will be weak. So experiment aboutincreasing interfacial strength is in process. In this study, the change of properties by mechanical, interfacial andmicromechanical tests was observed after NaCl and aging treatment. The changes in mechanical properties of glassfiber were investigated using single-fiber tensile test. Interfacial properties between glass fiber and epoxy resin wereevaluated using nondestructive acoustic emission (AE) and micromechanical test applied to fatigue test. Throughchange of fatigue properties, relative interfacial properties were evaluate. In conclusion, glass fiber diameter decreasedand the reduction of mechanical and interfacial was observed with NaCl solution and aging treatment.
