The tube is made of polymer composite material based on K-153 epoxy resin (K-153 epoxy resin is made from ED-20 epoxy resin modified by thiokol and oligomer acrylate), T-13 glassfiber, hardener polyethylenepolyaminemade by wrapping on machine. The effect of drying temperature on mechanical properties (tensile strength, flexural strength) of polymercomposite materialwas studied. The paper also mentions to select suitable hardener to beused for polymercomposite tube wrapping. The results show that the strength at break, flexural strength of polymercomposite material are changedmuch when changing wrapping angle. The drying temperature increases, the curing time of polymercomposite material is much reduced. The time to stabilize after drying also greatly affects the pressure resistance of polymer composite tubes.
Keywords
