“…Figure 4 clearly demonstrated that sulphur mutated simulant chemical molecules is adhered onto surface of the web and therefore, web is acting as a barrier layer for CWA sulphur mustard gas. On the other hand, air permeability, water vapour, and bacteria and chemical filtration results of functional integrated layer showed agreement and correlation with those obtained by pore size and morphological measurements [24][25][26][27][28][29][30][31]. Nanoweb morphology act as a barrier layer is in close agreement with previously reported work for various other applications [32][33][34][35][36][37][38][39].…”

“…The pressure applied during the curing process further shrinks the nanointerleave, and most of the papers did not register any appreciable thickness increase due to the interleave. However, in the majority of the papers, just one nanofibrous mat is used, and in some of those cases where several mats are applied, increases of few % are registered; 4. mechanical properties: nanofibers' mechanical properties can be significantly higher than those of the same material in bulk state [103].…”

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.

“…Despite the potential utilization of electrospun nanofibers in many fields, their success has been limited so far due to their poor mechanical properties compared to those of fibers made by conventional processes such as melt-or solution spinning [4][5][6][7][8][9]. The main reason for this is the competition between flow-induced chain orientation and chain relaxation before fiber solidification, leading to low degrees of molecular orientation in as-spun fibers based on flexible chain polymer fibers [5]. It is for this reason that high performance fibers based on flexible chain polymers are typically post-drawn in the solid state below their melting temperature, where relaxation times are nearly infinite.…”

Abstract. Co-polyimide nanofiber based on BPDA (3, 30, 4, 40-Biphenyltetracarboxylic dianhydride)/PDA (p-Phenylene-diamine)/ODA (4, 40-Oxydianiline) (BPO) were produced by electrospinning followed by imidization from precursor polyamic acid (PAA) nanofiber. The aligned co-polyimide nanofiber mats possessed a modulus, strength and strain-at-break of respective 10 GPa, 1.04 GPa, and 13.5%. In comparison with previously reported co-polyimide nanofibers BPDA/BPA/ODA (BBO) with similar chemical structures, these BPO co-polyimide nanofibers can be as stiff and strong while at the same time exhibiting moderate ductility. On the other hand, the current BPO co-polyimide nanofibers exhibited a greater toughness than previously reported homo-polyimide (BPDA/PDA) nanofibers due to their relatively high strain-at-break, leading to similar levels of toughness as Kevlar fibers. A novel and efficient way to evaluate mechanical properties of aligned nanofiber bundles (~30 nanofibers in a bundle) by virtue of a micro-tensile tester was also reported. Young's modulus of 38 ± 2 GPa and tensile strength of 1550 ± 70 MPa were found for nanofiber bundles and were significantly higher than those of aligned mats, and are among the highest reported for electrospun fibers. Further evaluation of this bundle data using Daniel's theory based on Weibull statistics resulted in a predicted tensile strength of single copolyimide nanofibers of about 1.9 GPa.
