Application:the epoxy fiberglass tension stick rods, organic
composite insulators, tension and winding composite stick specially used for
tower cross arm which has the higher flexural strength than the tension stick
and 4 cm long winding insulator used for high voltage wirings.
What are the advantages of epoxy resin systems used for manufacturing FRP rods
in comparison to polyester resin systems?
Epoxy resins are impregnating compounds with the highest available quality of
all comparable polymers for the pultrusion of FRP rod materials. Hot curing
epoxy resin in combination with anhydride hardener gives an aging/hydrolysis
resistant high strength matrix component. Polyester resins are not hydrolysis
resistant and have lower mechanical and electrical properties
