Abstract: Epoxy-matrix composites are highly brittle and tend to fail catastrophically, which can be dangerous and costly. Therefore an area of great potential in composite manufacture is improving the toughness—that is, the energy absorption ability, of the polymer matrix. Including a second, less brittle polymer phase can increase the toughness of a composite, in turn enhancing the damping and impact energy absorption. In order to take full advantage of these enhanced properties, the adhesion must be sufficient that an applied load can be transferred between the two phases without causing adhesive failure. Adhesion behavior between epoxy and polyamide 6 elastomer is examined for compression molded samples using the wedge test. The influence of processing conditions on adhesion is also investigated. The strength of the bonds suggests that these matrix combinations provide viable avenues for toughening existing composite materials.
