“…However, as suggested above by the substantial preservation of the values of linear stiffness, commenting about results in Table 4, Figure 7c confirms there is no evident spalling from impact at 38.4 J for neither of the laminates. On the other side, the different complexity in the mode of damage shown by two laminates with not very different impact performance suggests the possibility to tailor damage creation in a laminate to the needs of the structure it is included in: this process would be further refined by the use of hybrid fabrics for reinforcement (e.g., flax/basalt hybrid leno weave [32]).…”

Ternary hybrids including carbon, basalt and flax fibres in an epoxy matrix have been fabricated by hand lay-up, then consolidated by vacuum bagging using two different stacking sequences. Both configurations involved the use of carbon fibres on the outside, whilst basalt and flax fibres were disposed internally either in a sandwich or in an intercalated sequence. They were subjected to tensile, flexural and interlaminar shear strength test, then to falling weight impact with three different energies, 12.8, 25.6 and 38.4 Joules, studying damage morphology and impact hysteresis cycles. Intercalation of basalt with flax layers proved beneficial for flexural and interlaminar strength. As regards impact performance, the differences between the two laminates were quite limited: however, the presence of a compact core of flax fibre laminate or else its intercalation with basalt fibre layers had a predominant effect on impact damage features, with intercalation increasing their complexity.

“…The most commonly reported formats are mats or compounds. Textile formats of flax fibers, including roving, yarns, and fabrics, have also been implemented as composite reinforcement materials in the literature (Bernava, Manins, & Kukle, ; Mehmood & Madsen, ). An extensive literature survey (Arbelaiz et al., ; Bodros, Pillin, Montrelay, & Baley, ; Bos, Mussig, & Van den Oever, ; Erasmus & Anandjiwala, ; Goutianos, Peijs, Nystrom, & Skrifvars, ; Li & Sain, ; Nystrom, Joffe, & Langstrom, ; Van den Oever, Bos, & Van Kemenade, ; Yu, Alcock, Rothwell, & McKay, ) on the mechanical properties (tensile modulus and tensile strength) of various types of flax FRPs clearly indicates that compression molding and injection molding are the main manufacturing processes applied to fabricate flax fiber reinforced composites.…”

The present study combines the generalized rule-of-mixture (ROM) model and the Ashby material selection method for the life cycle assessment (LCA) of flax fiber reinforced polymers (FRPs) and glass FRPs (GFRPs). The ROM model allows life cycle environmental impact predictions according to specific parameters of flax FRPs such as fiber format, volume fraction, manufacturing technique, and load-bearing capacity. The comparisons applied in this study are constructed on two common composite structures: mat panels and injection molded struts with equal stiffness and strength as the design criteria. On the one hand, the parametric LCA predicts that the equal strength design criterion for flax FRPs contributes to consistent mass increases, subsequently resulting in higher life cycle environmental impacts compared to the reference GFRPs; on the other hand, under the equal stiffness criterion the flax mat polypropylene (flax mat-PP) film helps with mass reduction in reference to the glass mat-PP composite, leading to the 20-50% life cycle environmental impact reductions for most impact categories. The subsequent evaluation of the influences of the fiber volume fraction on flax FRPs shows different patterns. For the short flax fiber-PP composite, a steady decrease of the life cycle CO 2 emissions can be observed with the increasing fiber volume fraction. However, for the flax mat-PP composite, depending on the tensile modulus of the flax fiber, the optimal volume fractions of the fiber change from 28 to 32% v/v, whereby the lowest life cycle greenhouse gas (GHG) emissions can be achieved.
