Abstract(s)
In this work, the effect of incorporation of recycled glass fibre reinforced plastics (GFRP)
waste materials, obtained by means of shredding and milling processes, on mechanical behavior
of polyester polymer mortar (PM) materials was assessed. For this purpose, different contents of
GFRP recyclates (between 4% up to 12% in mass), were incorporated into polyester PM
materials as sand aggregates and filler replacements. The effect of silane coupling agent addition
to resin binder was also evaluated. Applied waste material was proceeding from the shredding of
the leftovers resultant from the cutting and assembly processes of GFRP pultrusion profiles.
Currently, these leftovers, jointly with unfinished products and scrap resulting from pultrusion
manufacturing process, are landfilled, with supplementary added costs. Thus, besides the
evident environmental benefits, a viable and feasible solution for these wastes would also
conduct to significant economic advantages.
Design of experiments and data treatment were accomplish by means of full factorial design
approach and analysis of variance ANOVA. Experimental results were promising toward the
recyclability of GFRP waste materials as aggregates and reinforcement for PM materials, with
significant improvements on mechanical properties with regard to non-modified formulations.
