Abstract
This paper presents complementary data corresponding to characterization tests done for our research article entitled “Uniaxially aligned electrospun fibers for advanced nanocomposites based on a model PVOH-epoxy system” (Karimi et al., 2016) [1]. Poly(vinyl alcohol) and epoxy resin were selected as a model system and the effect of electrospun fiber loading on polymer properties was examined in conjunction with two manufacturing methods. A novel electrospinning technology for production of uniaxially aligned nanofiber arrays was used. A conventional wet lay-up fabrication method is compared against a novel, hybrid electrospinning–electrospraying approach. The structure and thermomechanical properties of resulting composite materials were examined using scanning electron microscopy, dynamic mechanical analysis, thermogravimetric analysis, differential scanning calorimetry, Fourier transform infrared spectroscopy, and tensile testing. For discussion of obtained results please refer to the research paper (Karimi et al., 2016) [1].

Summary
Engineering, material science, nanotechnology Nanocomposite materials, electrospinning. The huge potential of electrospun sub-micron aligned fiber arrays in reinforcing a composite material is demonstrated which can open up new possibilities in various fields. The data are useful for comparing purposes when addressing the influence of aligned electrospun fibers for reinforcing articles. Q4 Scanning electron microscope micrograph and image analysis results of electrospun fibers are illustrated. Original micrographs obtained from SEM of fracture surfaces of fabricated nanocomposites are presented to show the material microstructure and quality. Tensile test data obtained for all specimens and the corresponding stress–strain diagrams is depicted. The average diameter of the PVOH fiber was based on the measurement of $ 200 fibers by computer image analysis of scanning electron micrographs (Electrospinz SEM Analyser software, Electrospinz Ltd., New Zealand) [3]
