Abstract
Reinforcing bars for concrete structures, are made from a composite of a depolymerizable and repolymerizable thermoplastic resin and longitudinally oriented reinforcing fibers. These reinforcing bars provide excellent tensile reinforcement, and do not exhibit the corrosion problems of conventional steel reinforcing bars. The rebars are readily formed into a great many shapes that are adapted to many specialized reinforcement requirements.
