Improving aramid pulp dispersion in epoxy resin via the in situ preparation of SiO₂ on an aramid pulp surface

Aramid pulp (AP) is a highly fibrillated form of fiber， with excellent heat resistance, wear resistance, size stability, and other beneficial properties, that can be dispersed in rubber or resin matrix systems. Its fibrillation results in a large surface area. However, AP easily tangles and aggregates between fibers because of its large surface area. Consequently, it experiences difficulty in dispersing in matrices, especially when a relatively...
