▎ 摘 要
NOVELTY - The bar has a bar main body made of 40-90 wt.% of electrical-corrosion resistant (E-CR) glass fiber or basalt fiber and graphene resins. A rope or thread is adhered helically to an external part of the bar main body. USE - Polymer reinforced fiberglass bar. ADVANTAGE - The bar has high stability and high mechanical resistant effects and low thermal coefficients, and reduces transport time and labor working intensity. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a polymer reinforced fiberglass bar.
