Besides fire resistance, for Phenolic Composites (here-in-after PCs.), in actual, moisture resistance are also needed when they are applied to components in wet uses such as in Naval vessels and in offshore operations where direct water contact may be expected. PCs have so-called "Micro-porous" when they are made by normal GRP manufacturing techniques, which causes much larger amounts of water absorption in them to higherlevel of arrount 7. So, this figure, which indicate impending disaster in a polyester matrix laminate, has made some specifiers suspicious of the effect of the water on mechanical performance of PC in "wet" service. To solve this problem, a large amount work has been carried out by workers in UK and US. This paper is an attempt to explain that theeffect of the high water absorption of PCs in not the disaster that some "prophets" may foretell. Let's open our next door for better society much safetyfied by our own efforts with PCs. like in UK.
