Epoxy composite construction consists of bonding all of the materials and parts of the craft together with epoxy resin. The resulting structure has physical characteristics superior to the components by themselves. Composite construction includes a variety of building methods that use epoxy to protect the materials from moisture as well as hold the materials together. Epoxy resins, the key ingredient, are among the most versatile of thermoset plastics. They bond exceptionally well to a wide range of materials and are highly moisture resistant. Compared to polyester resins typically used in fiberglass boat construction, epoxies have greater strength, less shrinkage, better moisture resistanceand better fatigue resistance.

A modern day solution with history:

The first foam material specifically formulated for a marine environment was a poly vinyl chloride (PVC) and isocyanate blend (simply called PVC foam) created in Germany by Dr. Lindemann in the late 1930's and 40's. It has been rumored that this early version of PVC foam was used in the German E-boats and even in the famous 'Bismarck' battleship.
