A composite reinforcer that can adhere directly to a diene rubber matrix is usable as a reinforcing element for a pneumatic tire. The composite reinforcer includes at least one reinforcing thread, such as a carbon steel cord. Covering each thread individually or several threads collectively is a layer of a thermoplastic polymer composition. The thermoplastic polymer composition includes at least one thermoplastic polymer have a glass transition temperature that is positive, a poly(p-phenylene ether) (PPE), and a functionalized unsaturated thermoplastic styrene (TPS) elastomer having a glass transition temperature that is negative. The TPS elastomer includes a functional group selected from: an epoxide group, a carboxyl group, an acid anhydride group, and an ester group. A process for manufacturing such a composite reinforcer is presented, as well as a process for producing a rubber article, especially a pneumatic tire, incorporating such a composite reinforcer.
