A novel “three‐step approach” of methanesulfonic acid/γ‐aminopropyl triethoxy silane/GlycidylEthyl polyhedral oligomeric silsesquioxane (MSA/KH550/POSS) was proposed to functionalize the surface of high modulus poly ( p‐ phenylene‐2,6‐benzobisoxazole) (HMPBO) fibers. Results indicated that GlycidylEthyl POSS was successfully grafted on the surface of HMPBO fibers and the surface roughness of HMPBO fibers was increased obviously. The single fiber pull‐out strength of POSS‐ g ‐HMPBO/epoxy resin microcomposite was improved to 1.19 MPa, better than that of native HMPBO/epoxy resin microcomposite. POLYM.
