There are essentially two or three items to a composite:

• Gelcoat Layer - a very thin top layer which beautifies the product and gives chemical/water resistance to the glass/resin layers
• Resin - Polyester Resin in Styrene being the most popular, but epoxy and Vinyl Esters are used too.
• Glass Reinforcement - Wetted using resins, forms the majority of the strength of the composite
