The problems start to occur when the water molecules migrating into the GRP (fiberglass) encounter other chemicals inside the laminate, primarily water-soluble materials (WSMs) such as the emulsion binders used to hold the fiberglass mat together before it is molded, or pockets of uncured or partially cured resins in the hull mould. The water molecules can have a chemical reaction with these substances, forming larger molecules of a new chemical, often acidic - which unlike the original small water molecules, can not carry on passing through the GRP. These larger molecules are then trapped. This is the point at which osmosis actually starts.

The important parts are that the hull is not waterproof (it is a semi-permeable material), and that osmosis causes a low concentration fluid (water) to pass through the hull to join the higher concentration fluid (the chemical mix formed by the water plus WSM) inside the fiberglass laminate schedule.


Pressure is thus built up inside the laminate. If this process takes place in a solid part of the laminate, there is usually no problem as the structure is strong enough to contain the pressure. If however it takes place on the boundary of a small air-bubble in the moulding, or at a point where layers of fiberglass are not properly bonded, the new chemical compounds slowly fill up the bubbles or the very small gaps between layers with liquid. Almost all mouldings have these air bubbles and small areas of poor bonding... Read more...
