AI Technical Summary
The existing aramid paper pretreatment process has the problem of insufficient interlayer bonding strength, which leads to interlayer delamination or blistering, resulting in insufficient interlayer bonding strength of the insulation components.
A wet processing method is used to treat aramid paper. The method for preparing aramid paper prepreg includes the following steps: wet processing of aramid paper prepreg, using new equipment and materials for aramid paper prepreg, including wet processing, directional fiber layer construction, pre-pressing and discharge, interface reinforcement coating, thermal light source pre-curing, gradient curing and post-treatment.
It significantly improves interlayer bonding strength, toughness, and heat resistance, and enhances insulation properties, including higher dielectric strength and better creepage resistance, thus solving the problem of insufficient interlayer bonding strength in existing technologies.
