The use of light composites when designing fast moving parts for machine tools is emerging as a very efficient solution for improving productivity. Nevertheless several aspects of these materials have to be carefully considered in woodworking. This paper aims to investigate the effect of interleaved nanofiber on mode I interlaminar properties and the failure modes that occur in this mode. For this purpose, woven carbon/epoxy laminates with and without Polyvinylidene difluoride nanofibers in the mid-plane were subjected to mode I interlaminar loading and the results were compared with each other. Acoustic Emission technique was also utilized for better understanding of the failure modes that occurred in the virgin and nanofibersmodified specimens. Mechanical data and acoustic emission parameters associated with pattern recognition analyses were used for investigation of the interlaminar properties and the occurred failure modes. The mechanical results showed that the electrospun nanofibrous mat was able to increase the GIC by 98%. The AE results highlighted that different failure modes were the origin of different interlaminar failure behaviors. Different percentages of the failure modes in the 2 modified specimens compared with the virgin ones were observed. Furthermore, the number of occurred interlaminar failure modes diminished in the modified composite layers.

“…Also, nanofiber stretching, and eventual break absorbed a portion of energy. Bovicelli et al used polycaprolactone (PCL), nylon 6, 6 and Nylon 6, 6 + PCL nanofiber mats to interleave 20 ply carbon/epoxy composite at mid‐plane . PCL to Nylon 6, 6 ratio was 1:1 and PCL melted during curing of prepregs as against Nylon 6, 6 with melting point of 250°C.…”

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.

Composite materials are becoming increasingly important as structural materials for aeronautical and space engineering, naval, automotive, and civil engineering, sporting goods, and other consumer products. Fiber-based reinforcement represents one of the most effective manufacturing strategies for enhancing the mechanical strength and other properties of composite materials. Electrospinning has gained widespread interest in the last two decades because of its ability to fabricate continuous ultrafine nanofibers with unique characteristics. The impact of electrospinning on fiber synthesis and processing, characterization, and applications in drug delivery, nanofiltration, tissue scaffolding, and electronics has been extensively studied in the past. In this article, the authors have focused on a comprehensive review of the mechanical performance and properties of electrospun nanofibers as potential reinforcements as well as their advanced nanocomposites.
