Effect of Surface Treatment on the Properties of PPTA Fiber

Abstract:

In this article, the potassium permanganate solutions (KMnO₄) was used to treat the PPTA fiber based on an orthogonal experimental design. The optimum conditions of KMnO₄ treatment were concentration of 20%, temperature of 30°C and treating time of 20min. The interfacial properties of aramid fiber/epoxy composites were investigated by the single fiber pull-out test (SFP), and the results showed that the interfacial shear strength (IFSS) of aramid/epoxy composites was remarkbly improved.
