Abstract

This study highlights the investigation of different dielectric properties of non-interleaved carbon-epoxy and interleaved carbon-epoxy-nylon 66 nanofiber composite laminates. Carbon-epoxy quasi-isotropic composite laminates were developed in an autoclave using A 24-ply AS4/3501-6. Nylon-66 solution of 12 wt.% was prepared in dissolving crystals of Nylon-66 in the 90% formic acid and chloroform mixture with the weight ratio of 75/25, respectively. The nano fabric was developed by electro-spinning technique using prepared Nylon-66 solution. The fabric of 0.7g/m2 average aerial density and composite ply (AS4/3501-6) of 260 g/m2 average aerial density were observed. The interleaved laminates were developed using a nylon-66 nanofiber layer between the adjacent laminate flies. Measurement of some of the dielectric properties like dielectric constant, tan δ, and ac conductivity of the interleaved composite laminates was done at the frequency of range from 20 Hz to 10 MHz. Improvement in the different dielectric properties of the interleaved composite laminates was observed with the addition of a small wt.% of Nylon-66 nano fabric between the alternate layers of carbon-epoxy composite. A possible mechanism involved in the improvement of dielectric properties in the nanocomposites was reported in this paper.
