  "abstract": "In this work, performing materials from chemical and mechanical recycling of PA/Glass Fibers composites using the reactive extrusion process were developed. Through the reduction of the viscosity of the PA by chemical modification using amino-terminated polyethers Jeffamine® T403 and dimethyl terephthalate (DMT), the breakup of glass fibers was reduced. The decrease in melt viscosity, whether due to chain scission of PA6 or the formation of new branched structures within the polymer matrix had led to a significant improvement in processability. Although T403, when added alone, caused a slight negative effect on the mechanical properties, especially in terms of impact strength, the concomitant addition of DMT led to an improvement. This improvement in mechanical properties was attributed to the presence of longer GFs resulting from the lower viscosity of the medium and reduced shear damage, in addition to the formation of new structures that improve the mechanical properties of such composites. Furthermore, the study investigated the influence of two extrusion cycles on the composites mechanical properties and found that although ultimately decreased, the ultimate strength of T403 and DMT based composites remained superior to those of PA6/GF alone. This suggests that the addition of Jeffamine® T403 and DMT not only improves the initial properties of the composites but also enhances their recyclability. This study showed how through reactive extrusion and small quantities of modifying agents, the recycling process does not only become less energy consuming but also reduces the breakage of GF's and creates in situ branched resin-like structures that enhances the mechanical properties of PA with or without the presence of GF's.",
