What is used in making fiberglass?
The vast majority of the time polyester resin is used for making fiberglass. Occasionally a manufacturer will use epoxy for added impact strength….which is the case of G10 which is a fiberglass/epoxy blend. In addition to the resin, fiberglass is made of sheets of thin strands of glass which are quite strong. They can either be straight strands, chopped strands, or woven strands. Chopped strands are the cheapest and weakest, straight strands only offer strength in one direction so their uses are limited (for example they make excellent fishing poles since poles are always flexed sideways and you’re not trying to pull the pole apart, but would make very poor car body panels) Woven is the most expensive, and the strongest. It is what is used in most fiberglass handle materials….such as G10.
