Abstract

Boat or yacht hull has been built mainly by FRP composite materials. FRP boat hull manufacturing begins to be restricted after the year 2000 under international regulation on ocean environment safety. The alternative of FRP has been proposed by many boat builders and high strength aluminium is considered as its standard material. But high strength aluminium is very expensive as boat hull material. In this study, boat hull is considered to be built by high density polyethylene and its structural strength is estimated by longitudinal strength test method on small craft. Tensile strength of polyethylene boat hull material is higher than that of FRP boat hull material. But safety factor of polyethylene boat hull is more than that of FRP boat hull. These study results indicate structural integrity and quality control of polyethylene boat is better than those of FRP boat.

플레저 보트나 요트는 FRP나 알루미늄으로 제작되고 있으나 FRP는 해양환경오염으로, 알루미늄은 낮은 가격 경쟁력으로 인하여 해당 제품의 시장 지배력이 약화되고 있다. 따라서 본 연구에서는 선체를 폴리에틸렌으로 제작하여 일본소형선박검사사무규정세칙에서 제안하고 있는 소형선체에 대한 구조 안전성 평가 방법을 통하여 폴리에틸렌 선체의 구조 안전성을 확인한 결과, 폴리에틸렌 보트가 FRP 보트보다 매우 높은 구조 안전성을 보였다.
