“…PA 6.9, PA 11 or PA 12, have a higher elongation at break compared to PA 6 or PA 6.6 [35]. Furthermore, PA 6.9 has less moisture take-up compared to PA 6.6 which can have a positive effect on the quality of the resulting laminate [15,23]. The interlaminar fracture toughness in Mode I and Mode II of nanofibre interleaved composite laminates is determined by Double Cantilever Beam (DCB) and End Notched Flexure (ENF) experiments.…”

“…A linear lateral motion of the electrospinning nozzles perpendicular to the production direction guarantees the uniformity of the nanofibrous veils. A FA/AA mixture was used to dissolve the PA pellets for electrospinning solutions according to previous studies [15,34]. A 14 wt% 70:30 FA:AA solution was used to electrospin PA 6.6 nanofibres, and a 16 wt% 50:50 FA:AA solution was used for PA 6.9 nanofibres.…”

“…As mentioned by few authors [89,91,93], a main aspect to take into consideration when interleaving nanofibers in a laminate is their adhesion with the resin: it is affected by several factors (moisture of the nanofibers, process conditions such as pressure, temperature, and vacuum grade, etc.) and strongly influences the final performances of the laminate.…”

In the last few decades nanofibers have been developed and introduced in a vast number of industrial and research applications. One of their most effective use is as interleaved reinforcement for composite laminate materials against delamination. Nanofibrous mats have the ideal morphology to be embedded between two plies of a laminate, and a vast and deep research has been carried out investigating their effect on the global behaviour of a composite laminate. This review is the first of its kind to date which presents a detailed state-ofthe-art on the effect of nanofibrous interleaves into composite laminates with focus on the mechanical performances and behaviours of nanomodified materials. A detailed description of the working mechanisms of the nanointerleave under different load cases is presented, and a comparative analysis between papers in literature will provide readers with a powerful tool to understand and use nanofibers for reinforcing purposes.

Effects of Nylon 6,6 nanofibrous mats on thermal properties and delamination behavior of high performance CFRP laminates

et al. 2014

Nylon 6,6 electrospun nanofibrous membranes interleaved in "high performance" Carbon Fiber Reinforced Polymer (CFRP) laminates have been proposed as a means to provide a high threshold value to delamination on structural sites where composites are more prone to develop such failure. A model, highly crosslinked, thus inherently brittle, epoxy matrix was selected for its high Young's modulus and glass transition temperature exceeding 250 C. The influence of the Nylon 6,6 nanofibers on the curing behavior of the matrix and on the thermal and dynamic mechanical properties of the cured resin was investigated. These properties were related to the features of the epoxy resin and of the resin impregnated nanofibrous mat. Finally, the delamination behavior of the composite laminates interleaved with Nylon interleaves with different thicknesses was studied through Mode I delamination tests on Double Cantilever Beam (DCB) samples. The results show that the initial Mode I fracture toughness was increased up to about 50% by the presence of the thin mat interleaf. POLYM. COMPOS., 36:1303-1313, 2015
