Fiberglass woven cloth are woven from yarns of glass filaments. There are two types of glass that are used for Surfboard fabric, E-glass and S-glass. The chemical composition of the glasses is different and yield different properties. E-glass is the most common glass fiber and is produced in huge quantities and is inexpensive. S-glass is produced in smaller quantities and is more expensive but has higher physical strength properties than E-glass. The tensile strength of S-glass is about 50% higher than e glass cloth and it is 25% stiffer in flex. We have found that using S-glass on the decks of boards reduces heel dings and prolongs the life of the board.
The plain weave consists of yarns interlaced in an alternating fashion one over and one under every other yarn. The plain weave provides good fabric stability but is generally the least pliable.
The twill weave is more pliable than the plain weave and has better drapability while maintaining more fabric stability than a four or eight harness satin weave. The weave pattern is characterized by a diagonal rib created by one warp yarn floating over at least two filling yarns.
Fiberglass Fabric Has Many Features:
Good performance in chemical corrosion resistance
Plain weave, even thickness and low fuzz
High strength in both warp and weft direction
Easily impregnated with resin, high cohesive strength
E-Grade Fabric has excellent electricity insulation property
surfboard fiberglass cloth also have a finish on them, the finish is there to help the resin bond to the glass fabric and to help it wet out completely. Early fiberglass and foam surfboards were built with existing fiberglass boat fabrics, which were finished with a volan finish. The volan finish produces a "coke bottle" green tint. Modern surfboard fabrics use a silane finish which goes absolutely clear. We usually stock volan fabrics but call for availability. The silane finish that we carry is compatible with both polyester and epoxy resins.
