“…The variation for reference and modified laminates was 0.6% and 6%. Daelemans et al used PA 6, PA 6, 9 and Polycaprolactone (PCL) nanofiber veils (6 and 12 g/m 2 ) to be interleaved in glass/epoxy composites for drop weight impact testing . [0°/90°] 2S stacking sequence with nanofiber at each interphase were chosen to be impacted at 14, 28, 41, 54, 67, and 79 J. Load‐time curves indicated steep drop in load at 54, 67, 67, and 79 J for virgin PA 6, PA 6,9, and PCL interleaved composites.…”

Electrospinning has by far proved to be the most successful method to spin high aspect and surface area to volume ratio nanofiber for multidisciplinary applications. Its application, however, as reinforcement in fiber reinforced polymer matrix composites (FRPC's) started from interlaminar fracture toughness improvement through interleaving. Since then, its usage both in short fiber and nonwoven mat formation has been phenomenally increased to tailor mechanical properties. This review paper focuses on application of nanofiber in multiscale reinforced epoxy matrix composites for mechanical performance. After a brief overview of electrospinning and spinning parameters, it presents a case for nanofiber as reinforcement with attendant mechanisms to develop insight into nanocomposite performance. Next, it summarizes and shares findings of studies, carried out in last 10 years, seeking to enhance tensile, flexural, interlaminar toughness, impact, and fatigue properties of epoxy composites through electrospun nanofiber reinforcement. Finally, it presents a perspective to gain headways in nanofiber reinforced FRPC's research through a variety of processing and material variables.

Electrospun nanofibre interleaving has a great potential for toughening of composite laminates as an effective, safe and industrially relevant method. Although many studies showcase large increases in delamination resistance, these are typically obtained under either Mode I or Mode II loading and for a wide variety of nanofibres. Here, we present a more general approach towards simultaneous excellent Mode I and Mode II delamination resistance using a single nanofibre system without the need for additional chemical modification steps or speciality polymers. It is illustrated based on the concept of interdiffusion of polycaprolactone nanofibres during the curing process into the epoxy matrix resin for improved adhesion. The results show that for a simultaneous increase in Mode I and Mode II delamination resistance, the adhesion and the fibre morphology of the nanofibres are crucial. The methodology is then expanded to allow for industrial relevant working windows by core-shell structured polyamide/polycaprolactone nanofibres. This approach results in a of 650 ± 50 J m-2 (+ ca. 60% vs. virgin material) and a of 3160 ± 35 J m-2 (+ ca. 60% vs. virgin material).

Carbon-fiber-reinforced plastic is an important building material; however, its application is limited because of its brittleness, leading to vulnerability under shock. Thus, the strength performance of carbon-fiber-reinforced plastics needs to be improved. Here, the drop impact test was conducted to analyze the impact energy and fracture characteristics of carbon-fiber-reinforced plastics and ethylene vinyl acetate sheets. The compression after impact test was performed to assess the residual compressive strength. The thermal energy generated was measured as change in temperature at the time of fracture to investigate the relationship between thermal and mechanical properties. The impact absorption efficiency of 100% was achieved when the carbon-fiber-reinforced plastics specimen was laminated with four or more sheets of ethylene vinyl acetate. The thermal energy generated during impact, the impact load, and the compression after impact test strength was reduced with the increasing number of laminated ethylene vinyl acetate layers. Our results showed that, by carefully selecting the optimal conditions of fabricating the carbon-fiber-reinforced plastic/ethylene vinyl acetate composites, carbon composite materials can be used for impact mitigation.
