Abstract: A composite article has an increased peel strength and includes a first layer including a low surface energy polymer. The composite article also includes a poly(meth)acrylate layer, an epoxide layer, and a polyurethane elastomer layer. The poly(meth)acrylate layer is disposed on and in direct contact with the first layer. Moreover, the poly(meth)acrylate layer includes a poly(meth)acrylate that includes the reaction product of at least one (meth)acrylate that is polymerized in the presence of an organoborane initiator. The epoxide layer is disposed on and in direct contact with the poly(meth)acrylate layer. The polyurethane elastomer layer is disposed on and in direct contact with the epoxide layer. The composite article has a 90° peel strength of at least 50 pli measured using ASTM D6862.
