Abstract
A formable reinforcement bar, a process for producing a formable reinforcing bar and a supported structure including a formable reinforcement bar are provided. The reinforcement bar includes a body portion of a fiber reinforced thermoplastic material. The process involves laminating multiple layers of thin strips or bundles of fiber reinforced thermoplastic to produce the formable rebar. The formable rebar may be produced at remote locations such as a construction site. The supported structure includes a composite material having a formable rebar embedded therein.
Claims16
A process for producing a formable reinforcing bar comprising:
- providing at least two layers, said layers comprising a thermoplastic polymer material having multiple continuous fibers completely embedded in said thermoplastic polymer material;
- passing said layers through a pre-treating zone to pretreat said layers;
- bringing said pre-treated layers into contact;
- passing said pre-treated layers through a lamination zone wherein said layers are compressed to form a laminated body portion, and
- passing said body portion to a post-treating zone whereby said body portion is post-treated thereby forming a reinforcing bar which is thermoformable after said reinforcing bar is produced.
