The Mechanical Properties of Nanocomposites Reinforced with PA6 Electrospun Nanofibers

Abstract

Electrospun nanofibers are very popular in polymer nanocomposites because they have a high aspect ratio, a large surface area, and good mechanical properties, which gives them a broad range of uses. The application of nonwoven structures of electrospun nanofiber mats has historically been limited to enhancing the interlaminar responses of fiber-reinforced composites. However, the potential of oriented nanofibers to improve the characteristics of bulk matrices cannot be overstated. In this research, a multilayered laminate composite was created by introducing polyamide (PA6)-oriented nanofibers into an epoxy matrix in order to examine the effect of the nanofibers on the tensile and thermal characteristics of the nanocomposite. The specimens’ fracture surfaces were examined using scanning electron microscopy (SEM). Using differential scanning calorimetry (DSC) analysis, the thermal characteristics of the nanofiber-layered composites were investigated. The results demonstrated a 10.58% peak in the nanocomposites’ elastic modulus, which was compared to the numerical simulation and the analytical model. This work proposes a technique for the development of lightweight high-performance nanocomposites.

A Finite Element Method for Determining the Mechanical Properties of Electrospun Nanofibrous Mats

“…The applications of nanofiber mats are diverse, ranging from drug delivery [ 3 ] to filtration [ 4 , 5 ], nanocomposites [ 6 ], wound dressings [ 7 ], energy harvesting [ 8 ], protective gear [ 9 ], and tissue scaffolding [ 10 ]. A crucial aspect of leveraging these mats in various applications is understanding their mechanical behaviors, which necessitates a deeper analysis based on the mechanical properties of the individual nanofibers.…”

Measuring Physical Properties of Electrospun Nanofiber Mats for Different Biomedical Applications

“…One of the problematic methods is using a micrometer caliper since its pressure limitation is usually not sufficient to avoid compression of fine nanofiber mats, similarly to microscopic textile fabrics. Liu et al tried to compensate for this effect by folding the membranes twice before measuring, i.e., by measuring four layers instead of only one [ 57 ], while other groups did not comment on this problem [ 125 ]. A typical textile thickness measurement instrument, which has a larger measurement area and causes less pressure on the investigated sample, was applied by Pakolpakcil et al, who used a digital thickness gauge for nonwovens and measured at 10 points on the nanofiber mat [ 126 ].…”
