Abstract

Since the current amine and phenolic amine curing systems used in insulated booms suffer from high internal stress, defect susceptibility, and a narrow processing window, leading to reduced long term durability and limiting reliable application in high voltage and high strength environments, the work aims to systematically investigate a resin system suitable for high performance insulated booms and conduct in-depth analysis on its curing process and glass transition temperature (T_g), to improve the comprehensive performance and reliability of the material. Differential scanning calorimetry (DSC) was used to obtain curing exotherm data at different heating rates, based on which the optimized theoretical curing temperature profile and curing temperature parameters were derived. A phenomenological model was employed to establish the curing kinetic equation and verified with isothermal DSC data at 120 ℃. Based on the DiBenedetto equation, a mathematical model linking the glass transition temperature and the degree of cure was developed. The optimized theoretical curing process parameters of the resin system were determined. The curing kinetic model agreed well with experimental data, which verified the reliability of the model. A quantitative relationship between the degree of cure and the glass transition temperature was established based on the model. After post curing, the resin's T_g increased to 128 ℃, indicating that post curing effectively promoted the formation of a cross linked network and significantly enhanced the cross linking density. A curing kinetic model and a glass transition temperature prediction model for the resin system suitable for high-performance insulated booms are systematically established, providing a theoretical basis for process optimization. The results show that appropriate post curing treatment can significantly increase the glass transition temperature and crosslink density of the resin, which helps improve the long-term durability of insulated booms and offers guidelines for determining curing process parameters for their reliable application under high voltage and high strength operating conditions.
