Abstract:
A method for forming a pre-cure rebar product comprising a core, cladding layer, and an outer shell, comprising the steps of:(a) pultruding a first reinforced material to form an inner core;(b) forming a second reinforced material into a cladding layer over said inner core;(c) manipulating a malleable material layer to form two longitudinally extending channels, wherein one of the longitudinally extending channels is configured to define a first malleable shell portion and the other is configured to define a matable second malleable shell portion;(d) positioning the first and second shell portions on opposing sides of said core and cladding layers;(e) then enclosing said core and cladding layer with said first and second shell portions to form a malleable outer shell therearound, resin of the cladding layer flowing into the first and second shell portions; and(f) attaching said shell portions together to form said pre-cure rebar product, wherein said malleable outer shell is sufficiently ductile to take on a shell configuration and sufficiently rigid so as to retain said shell configuration.
