Abstract
A reinforcing bar comprising a core is provided. The core comprises ultra-high-molecular-weight polyethylene fibers aligned in an axial direction and a polyethylene matrix. The ultra-high-molecular-weight polyethylene fibers are bound in the polyethylene matrix. A shell comprising ultra-high-molecular-weight polyethylene tape surrounds the core in a radial dimension.
Claims20
A reinforcing bar comprising:
- a core comprising ultra-high-molecular-weight polyethylene fibers aligned in an axial direction and a polyethylene matrix, wherein the ultra-high-molecular-weight polyethylene fibers are bound in the polyethylene matrix;
- and
- a shell comprising ultra-high-molecular-weight polyethylene tape surrounding the core in a radial dimension.
A process for manufacturing one or more ultra-high-molecular-weight polyethylene reinforcing bars comprising:
- aligning a plurality of ultra-high-molecular-weight polyethylene fibers in an axial direction;
- partially melting the plurality of ultra-high-molecular-weight polyethylene fibers by applying heat and pressure to the plurality of ultra-high-molecular-weight polyethylene fibers;
- cooling the plurality of ultra-high-molecular-weight polyethylene fibers to form a core comprising the plurality of ultra-high-molecular-weight polyethylene fibers and a ultra-high-molecular-weight polyethylene matrix, the plurality of ultra-high-molecular-weight polyethylene fibers bound in the ultra-high-molecular-weight polyethylene matrix;
- and
- applying an ultra-high-molecular-weight polyethylene tape to the surface of the core.
