A rebar forming apparatus includes a malleable material supply station for continuously supplying a malleable planar material and a malleable material forming station for forming the malleable material into first and second corresponding shell portions and related rebar products. The apparatus also includes a core pultrusion station and a cladding forming station for respectively forming core and cladding layers. A shell forming station is positioned downstream of the core and cladding forming stations which unites the first and second shell portions to form an outer shell with the core and cladding layers contained therein. The rebar product includes shell portions which are matably configured to form a disposable outer shell over the core and cladding layers. Related reinforcing composite product forming methods also include the use of a removable outer shell.

1. A method for forming a rebar product comprising a core and a cladding layer, comprising the steps of:pultruding a first reinforced material to form an inner core; forming a cladding layer comprising a resin material over said inner core; forming two longitudinally extending channels from a malleable material layer, 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; positioning the first and second shell portions on opposing sides of said core and cladding layers; then enclosing said core and cladding layer with said first and second shell portions to form a malleable outer shell therearound with the cladding layer flowing into the first and second shell portions; and attaching said shell portions together to form the rebar product; wherein said malleable outer shell is sufficiently ductile to take on a shell configuration in advance of said enclosing step.
