“…Also, can be noted that those holes have diameters similar to small HGM, about 6 µm. It was expected since a low ratio surface comes with a low adhesion surface between matrix and non-treated HGM [34,35] . Figure 6a show the adhesion failure in sample D (70%PA6/ 22,5%GF/ 7,5%HGM) with a zoom.…”

The strategy of combining the traditional reinforcement of glass fibers (GF) with lighter hollow glass microspheres (HGM) can afford to fulfill the need for potential light-weight and high-strength modern materials required in various sectors, such as automotive and aerospace industry applications. This work fabricated composites of PA6/GF/HGM by melting blending in a co-rotating twin-screw extruder, and subsequently, injection molded. The effects of HGM content on the density, morphological and mechanical properties were investigated and the PA6/GF/HGM composites properties were compared to the properties of the traditional PA6/GF (70/30) wt% composite, widely used today in automotive industries. With the increase of HGM amount in the formulations, a reduction of between 3 and 12% in density was achieved with a slight reduction in its mechanical properties, showing that this new strategy can be applied to replace the PA6/GF (70/30) wt% composite, providing a considerable weight reduction for these materials.

“…Their results showed the enhancement of failure strain of glass/epoxy composite when hybridized with a thermoplastic composite; however, it was left unnoticed. Bauer et al 37 improved the interfacial strength of hybrid thermoset-thermoplastic composites (carbon/epoxy and short glass/polyamide) using low-pressure plasma. Three different surface treatment techniques (surface silanization, CO 2 laser ablation and plasma treatment) were adopted by Ding et al 41 to assess the interface properties of hybrid thermoset-thermoplastic composites.…”

Though fiber reinforced thermoset composites exhibit excellent rigidity and strength while being lightweight, they suffer from low toughness and brittle failure, which is unfavorable. On the other hand, fiber reinforced thermoplastic composites are good energy absorbers, damage resistant and recyclable; however, these materials exhibits insufficient rigidity. As a solution, the interlayer hybridization of glass fiber reinforced thermoset (GTS) and glass fiber reinforced thermoplastic (GTP) composites is proposed. This study aims at investigating the tensile properties of interlayer hybrid thermoset-thermoplastic composites. In this regard, two non-hybrid and two hybrid composite samples (GTS2-GTP and GTS4-GTP) were fabricated using common fabrication techniques: hand lay-up and hot compression molding. Both hybrid composite samples were fabricated in such a manner that GTP was sandwiched between two GTS plates. Based on the tensile test results, the failure strain of GTS sample was improved due to the interlayer hybridization with GTP. Non-hybrid composite samples exhibited one load drop in their tensile stress-strain behavior, while interlayer hybrid composites showed two load drops, which resulted in toughness increment. Moreover, hybrid thermoset-thermoplastic composites outperformed non-hybrid composites in terms of post-impact tensile properties.

“…According to the published literatures, the surface pretreatment methods of polymeric surface, such as coupling agent method, 15 physical high-energy radiation treatments including plasma 16,17 and laser processing, [18][19][20][21] flame surface treatment, 22 have been commonly used to improve the adhesion between polymeric material and other material. Especially, Bauer et al 17 successfully fabricated overmolded thermoplastic-thermoset composites with high interface adhesion strength through pretreating the continuous fiber reinforced epoxy composites with low-pressure plasma. Nevertheless, improving the interface adhesion of overmolded thermoplastic-thermoset composites through surface pretreatment and the related bonding mechanism have been very rarely reported.…”
