Where I live I am able to go surfing, and so my surf board is made from fibreglass. Not all surfboards are made from fibreglass others are also made of Epoxy.
Fiberglass surfboards can have better flex out in the waves than an epoxy surfboard, but are easier to damage.
Fiberglass boards are better at catching waves, perform smoother, and are better harder and stiffer. In my personal opinion these boards are a lot better then Epoxy boards.
How a Fibreglass Surfboard is Made?
A fibreglass surfboard involves a significant amount of hand shaping in both the preparation of the core or polyurethane foam blank, and the final sanding to get the finished product just right.
The blank is shaped as far as possible to the board’s specifications and a piece of wood is incorporated into the middle of the blank for added stiffness and durability. The blank is then covered with a fibreglass cloth and laminated with polyester resin. The board is left for a while to allow the resin to set, and then the board is sanded to the final form.
