PLURAL-COMPONENT, COMPOSITE-MATERIAL HIGHWAY DOWEL BAR FABRICATION METHODOLOGY |
摘要 |
A method for making a plural-component, composite-material, highway dowel-bar including (1) preparing an elongate core train possessing endo-abutting, longitudinally alternating, (a) elongate, high-shear-strength, cylindrical cores having a common cross section, and (b) elongate, but shorter, cylindrical, fibre-reinforced plastic-resin end-plug blanks having opposite ends, and each having a cross section matching the cross section of the cores, (2) using the core train as a longitudinally moving mandrel, pultrusion-forming a fibre-reinforced plastic-resin sleeve continuously and bondedly around the core train so as to produce a pultrusion-result, intermediate, dowel-bar product, and (3) following pultrusion-forming, cross-cutting the intermediate, dowel-bar product at each longitudinal location therein which is intermediate the opposite ends of the end-plug blanks, thereby to form completed dowel bars. |

1. A plural-component, composite-material highway dowel bar comprising
an elongate, cylindrical, steel core having a long axis, and an elongate, fibre-reinforced plastic-resin jacket covering the core, said jacket including an elongate, cylindrically tubular sleeve which is fibre-reinforced in plural, plastic-resin-embedded, fibre-differentiated, circumferentially-adjacent circumferential layers of fibres. |
