선박용 프로펠러축 방식처리용 복합재료의 제조와 그 정적 및 피로특성 평가에 관한 연구
A Study on the Processing of Anti-Corrosive Composites for Propeller Shaft of the Ship and the Evaluation of Its Static and Fatigue Properties
초록
Kind 1 propeller shaft in ships is the shaft which is provided with effective measures against corrosion by sea water, or the shaft which is made of approved corrosion resistance materials. The propeller shaft other than specified above is Kind 2. Thus, this study is mainly concerned with the resistance to fatigue damage in sea water against stress concentrations due to the notches. The results obtained can be summarized as follows; (1) The stress increases with curing time, however, when the curing time reaches at 96 hours the stress becomes a constant value. The elongation decreases with curing time, however, when the curing time reaches at 48 hours the elongation becomes a constant value. Thus, in case of FRP coating on propeller shaft, it is necessary to cure for 48 hours at least. (2) The relation of
