Numerical investigation of the influence of the technological parameters of the fibre-reinforced polymer bar curing process in a curing oven.

A numerical investigation was conducted for clarifying the influence of the technological parameters of the process of a fibre-reinforced polymer bar curing in a curing oven on the fibre-reinforced polymer bar thermal state and the degree of the binder curing. The temperature fields and the degree of the binder curing in the fibre-reinforced polymer bar 10 mm in diameter were calculated after the fibre-reinforced polymer bar needletrusion at speed of 1.5 m/min in a four- section curing oven 4 m in length. A temperature condition was selected for each section of the oven, which provided the required degree of the binder curing and prevented thermal destruction of the fibre-reinforced polymer bar material.
