Yea, fiberglass rebar is garbage, im referring to glass fiber reinforced nylon. Most resin based fiberglass rebar has little to no shear or compressive strength. It's tensile strength is not comparable by dimension, but more so by weight, makgin the rebar bulky and impossible to use effectively. I have however used it in driveways and stuff, works fine for that. I wouldnt suggest fiberglass taking anything over, however engineered materials using waste plastics or reformulations may very well do just that. Already starting to see 5 AND 10% ABS granules in concrete mixes because it is effectively as free as sand right now. At those low percentages it doesnt compromise the concrete in any way.
FRPC Rebar, it is a extreme tension material not a compressive or shear. It's use would be under tension, such as tie in wrapping. Also a new material on the market is aramid fiber reinforced plastic (generalization for plastic its either going to be nylon or polyethylene). This last one is already in use on repair work, why? Because it's one of the few nonreactive materials that can be used on a repair job, strapping job or in some cases cabling. It is effectively stronger than steel by dimension and about 1/3rd the weight, current uses include
winch cable and light weight add on armor for military vehicles. best uses are subsurface, salt water environments or in buildings where they may be subjected to corrosive environments. Another use is in reinforced buildings for storm shelters or...even bomb shelters as FRPC can maintain it's integrity even if the concrete is largerly compromised.
