Aramid Fibers

The diameter of fibers is a critical factor in determining their final applications. When the diameter of aramid fibers changes from microns to nanoscale, its range of applications will be greatly extended. In this short review, the preparation of aramid nanofibers (ANFs) with diameters from ten nanometers to more than one hundred nanometers is introduced. Due to their excellent mechanical properties and their chemical and thermal stability, ANFs have been widely used as novel nanomaterials and composited with other materials, mainly for use in reinforced composites, energy storage, filtration and adsorption, biomedicine and electromagnetic fields. In this short review, the application of ANFs and their composites during the last 10 years is concisely summarized and a brief perspective on ANFs and their composites is also presented.

Abstract This work was focused on studying the properties of epoxy (EP) composite materials reinforced with glass, (GF) carbon (CF) and aramid (AF) fibres. The composites were made by hand lay-up (HL) and vacuum infusion process (VIP) with 8, 10, 12 number of fabric layers. Studied were tensile strength, elongation, flexural stress, flexural strain, thermal stability, texture of surfaces, cuts, fractures of laminates and the thickness of the laminate according to the type and number of layers of fabric and the method of manufacture. Composites made by VIP achieve better mechanical properties than composites made by HL. Tensile strength was highest in composites reinforced with AF. Composite materials reinforced with GF exhibit the lowest values of tensile strength. Flexural strength was significantly the highest in CF reinforced composites followed by the laminates reinforced with GF and AF. The highest values of flexural deformation were measured in composites reinforced with AF and the lowest values of flexural deformation were measured in composites reinforced with CF. By thermogravimetric analysis (TGA) was recorded weight loss of the EP matrix in the range from 290 to 480 °C and AF in range from 530 to 605 °C. By TGA was demonstrated lower content of EP matrix in the composites made by VIP, which was confirmed by comparison of thickness of the studied laminates.
