Abstract：

Maleic　anhydride　(MAH)　was　used　to　corrode　aramid　fibers　(AFs)　in　order　to　improve　the　interfacial　compatibility　between　AFs　and　polyamide　6　(PA6)　and　increase　the　mechanical　properties　of　AFs/PA6　composites.　PA6　was　mixed　with　AFs　treated　with　different　time　gradients　uniformly　and　the　standard　samples　of　AFs/PA6　composites　were　injection　molded.　FE-SEM,　XPS,　XRD　and　DSC　were　used　to　study　the　surface　morphologies　and　element　contents　of　AFs　and　the　impact　fracture　surface　morphologies,　crystal　form,　grain　and　crystallinities　of　AFs/PA6　composites.　The　results　show　that　surface　roughness　and　surface　oxygen　content　of　AFs　reach　the　maximum　after　corrosion　for　3　h.　The　introduction　of　corroded　AFs　is　beneficial　for　PA6　to　refine　grains　and　form　α　crystal.　The　inner　of　AFs/PA6　composite　samples　tend　to　form　α　crystal　easily　and　the　crystallinity　has　been　improved　compared　with　PA6.AFs/PA6　composites　have　higher　tensile　strength　and　bending　strength　after　the　addition　of　surface　treated　AFs,　and　mechanical　properties　of　AFs/PA6　composites　achieve　maximum　value　when　AFs　are　corroded　for　3　h.　©　2016,　BUAA　Culture　Media　Group　Ltd.　All　right　reserved.
