Crossbow Building Wiki

Fiberglass is considered by many to be the ultimate bow material. It is tough, light, extremely flexible, and does not degrade over time. However, it is quite difficult to work with compared to wood, therefore it requires abrasive tooling or extremely specialized and expensive forming equipment.

Disadvantages :-

Expensive compared to wood

Nasty to work with - glass fibers cause infected splinters and also cause really nasty lung diseases.

Fibrous - Can split fairly easily

Advantages :-

Holds a LOT of energy

Incredibly strong and light

Requires less skill than wood.

Modern fiberglass laminates are justifiably popular. They are made from glass fiber backing and belly over a tapered wood core. This allows the bows to be fairly consistent in width, making tillering easier. However, with crossbow prods which are sharply tapered compared to fiberglass, the fiberglass can split if not worked correctly.
