So I ask... is fiberglass itself or a similar make of fiberglass/epoxy resin (for example a floor stringer that is supposedly all fiberglass makeup) conducive to tensile strength in the manner of, let's say, inserting a 3/8" x 16 x 2" lag screw into the material, holding something such as an engine mount, in place for setting the engine? The stipulation to this question is that there is no wood or other composite in-lay of material involved. Strictly a fiberglass stringer, per se.....
I ask this on the same theory of a concrete masonry unit... the CMU is great in compression but is very weak in tension.
Will fiberglass take good hold with a lag screw in a tension load?
