Abstract
Abstract A reinforcing member for civil and architectural structures is made up of a mixture of reinforcing fibers and thermoplastic fibers which become thermoplastic at a temperature which is lower than a temperature at which the reinforcing fibers become thermoplastic. The thermoplastic fibers may be mixed into each bundle of the reinforcing fibers. The mixture may be formed by arranging respective fiber bundles of the reinforcing fibers and fiber bundles of the thermoplastic fibers. It may also be made by mixing the thermoplastic fibers and an electrically conductive heat-generating wiring material into the reinforcing fibers.
