Design and production technology of natural fibre reinforced polymers not only aims to offer products with a lower environmental impact than conventional glass composites but also caters for designers’ needs the fabrication lightweight free-formed architectural components. To combine both characteristics, forming process itself, once scaled up, be based on efficient material moulding strategies. Based case studies adaptive techniques derived from composite industry concrete casting, two approaches mass customised NFRP profiles are proposed. Both processes foam recycled PET, which is used as either removable mould or stay-in-place (SIP) core. Once textile reinforcement placed mould, by helical winding prepregs in form mass-produced preforms, its elastic properties allow free-forming profile before resin fully cured. This paper investigates range deformations that it possible achieve each method describes realisation small structural demonstrator, stool, through flax prepreg SIP
