Journal ArticleDOI
Grinding characteristics of carbon fiber epoxy composite hollow shafts
TL;DR: In this article, the grinding characteristics of composite hollow flexible shafts were investigated experimentally and analytically with respect to stacking sequence and stiffness of carbon fiber epoxy hollow composite shafts.
Journal ArticleDOI
Development of the anode bipolar plate/membrane assembly unit for air breathing PEMFC stack using silicone adhesive bonding
Minkook Kim,Dai Gil Lee +1 more
TL;DR: In this paper, an anode bipolar plate/membrane assembly unit which was bonded with the silicone adhesive was developed to solve the hydrogen leakage problem, and the reliability of the assembly unit was estimated under the internal pressure of hydrogen by the FE analysis.
Journal ArticleDOI
Design of the hybrid composite journal bearing assembled by interference fit
Seong Su Kim,Dai Gil Lee +1 more
TL;DR: In this paper, a hybrid composite journal bearing (HCJB) composed of carbon/phenolic laminated composite bush and steel housing was designed for marine vessels because it reduces the possibility of the seizure problem between the journal and bearing.
Journal ArticleDOI
Effect of the smart cure cycle on the performance of the co-cured aluminum/composite hybrid shaft
TL;DR: In this article, a smart cure cycle composed of cooling and reheating cycles was applied to reduce the thermal residual stresses generated during co-cure bonding stages due to the difference of coefficients of thermal expansions (CTE) of the composite and the aluminum tube.
Journal ArticleDOI
Failure analysis of asbestos–phenolic composite journal bearing
Dai Gil Lee,Seong Su Kim +1 more
TL;DR: In this paper, the failure of a large journal bearing made of asbestos reinforced phenolic composite for marine applications was investigated using finite element method with respect to the interference fitting amount during assembly and the temperature difference between the assembly and operation.
