에로전 실드의 접착특성에 미치는 접착 막의 흡습의 영향

The properties of adhesive film are degraded by environmental factors such as moisture or salinity. From this reason, this paper has studied about the degradation of adhesion properties between blades and erosion shield for hovercraft by moisture absorption. We performed the test of adhesion properties after surface treatment on STS304 and A6061. Therefore, we could have known that adhesion properties were decreased about 50% because of produced crack inside of adhesive film by moisture absorption through observation of specimens that immersed for ten weeks.
