“…Likewise, (Fiore et al, 2016), confirmed and prove a better durability for an hybrid composite with two external basalt layers. (Raponi et al, 2022). shows that the intraply arrangement of flax and basalt was especially useful in improving the tensile properties of flax-based laminates by 116% and 69% for ultimate strength and modulus.…”

“…The moisture variation for RH50 plotted in Figure 4 shows a significant difference between the composites Basalt/PA11 (0.42% moisture content) and Lin/PA11 (2.22% moisture content); in fact, the basalt fibers are mineral fibers and have excellent moisture resistance (Raponi et al, 2022), (Fargassa et al, 2018). Regarding the hyb5050/PA11 composites, the moisture uptake (1.33%) remains lower than that of flax, indicating that the hybridization allows reducing the moisture sensitivity.…”

“…Hybridization can result in a trade-off between mechanical properties and economic cost in order to meet the application requirements. Several recent studies show that the mechanical properties can be adapted by using hybridizations based on basalt fiber laminates with other natural fibers (Raponi et al, 2022), (Fargassa et al, 2018), (Petrucci et al, 2013), intending to provide a more durable material. These studies mainly focused on the impact and mechanical characterization properties of a basalt/ flax hybrid composite.…”

Environmental impact is becoming increasingly important in the automotive industry, with car manufacturers looking to reduce CO2 emissions through cleaner engines and structural weight reduction. Composite materials offer an excellent alternative to standard steels with significant weight reduction and the ability to produce functional parts (Rangappa et al., Polymer Composites, 2022,43, 645–691), (Jeyaguru et al., Polymer Composites, 2022, 43, 3902–3914), (Sanjay et al., Journal of Cleaner Production, 2018, 172, 566–581). The main objective of this study is to investigate the potential of a new and unique hybrid bio-composite material combining flax and basalt fibers and PA11 polymer. This material design is studied with the idea of reducing the moisture sensitivity, variabilities, and uncertainties of vegetal fibers by the presence of basalt fibers. The first step consists of developing a new hybrid composite material and studying its quasi-static mechanical behaviour when subjected to different humidity levels. Then, a multi-scale non-linear homogenization approach is proposed to support the interpretation of the characterization test results. The experimental results show the benefits of the hybridization. In fact, the hybrid composite is 20% stiffer than the flax/PA11 composite, 8% lighter than the basalt/PA11 composite and has a reduced dispersion of its mechanical properties, 52% lower than the flax/ PA11 composite. Considering the promising properties of the hybrid composite, we have investigated the possibility of developing the front hood of a sports car using this material. The first results highlight a potential mass gain of 18% at iso-performance with the original front hood. The following steps will be devoted to the numerical and experimental validation.

“…Demirci et al 28 also used basalt fiber and glass fiber in the structure of hybrid composite for manufacturing of pipes with the aim of improving low velocity impact behavior of these pipes in confronting with possible kicks during service life. Raponi et al 29 hybridized flax fiber with basalt and studied their damage tolerance under low velocity impact test. The results of this research showed a significant improvement in the quasi-static mechanical properties and damage tolerance of the basalt/flax hybrid composites compared to the pure flax-based laminates.…”

Nanoparticles are considered as feasible strengthening agent which strengthen different types of polymeric materials with minor reduction in the density of composites. In this study, 0.1 and 0.5 wt. % Graphene Nano Platelets (GNPs) are added to the matrix of basalt fiber reinforced epoxy composites (BECs) and the effects of such addition on low velocity impact behavior are investigated. In this regard, the epoxy matrix is reinforced in macro scale by basalt fibers weaved together in 2/2 Twill pattern. Vacuum Assisted Resin Infusion Molding (VARIM) method is used to fabricate the pure and multi-scale BECs. The profile energy method is also used to evaluate the penetration and perforation threshold of fabricated pure and multi-scale BEC specimens. The force versus time and deflection, energy and deflection versus time curves are plotted and the key parameters of low velocity impact test including maximum force, energy and deflection are compared. According to the results, introducing of GNP nanoparticles in the matrix of BECs improves the low velocity impact behavior of these composites by increasing the contact force and decreasing the absorbed energy in rebounding state. Finally, based on the experiments, the 0.5 wt.% BEC has the best impact performance by applying 15.08 kN impact force against the applied forces of 13.78 kN and 11.208 kN for 0.1 wt.% and pure BECs.
