abstract

  • The surface modification and adhesive bonding of a bidirectional glass reinforced polymer (GRP) composite have been investigated. Wettability studies showed that grit-blasted and plasma-treated specimens provide a
    significant increment in the surface energy, relative to untreated
    material. The most effective treatment found was grit blasting. The
    surface modification resulted in significantly improved adhesion between
    the composite and the applied toughened acrylic adhesive; a
    considerable increase in failure strength and in fracture energy was
    observed following grit blasting and grit blasting plus silane
    treatment. Specimens treated with atmospheric plasma showed a reduction
    in mechanical properties, resulting in interfacial (adhesion) failure.
    The durability was tested using the wedge test. Specimens treated with
    atmospheric plasma showed a lower durability than the other surface
    treatments.
