Is fiberglass resin strong?
While the exact number for the specific strength of fiberglass varies depending on the specific composite, a good average is about 1,307 kN m/kg. For comparison, stainless steel’s specific strength is 63.1, and titanium is 260. That’s a massive difference in favor of fiberglass.
