Steel frame bolted together with epoxy grout has been used by Madvac and other Zoners to acheive squareness.The problem is when the epoxy heats and crosslinks it flows out.Kevlar pulp or merge makes epoxy extremely thixotrop and it will not flow out of the joint.Kevlar pulp has no use in E/G as it is an extreme thixotrop and would hinder high epoxy aggregate ratios.Bolted joints reduce vibration and kevlar has high vibration loss.
