A microwave dielectric spectroscopy for detecting adhesive disbonds between acrylic glass (aka Poly (methyl methacrylate)) was discussed. The adhesive bond was developed using epoxy resin and acrylate. The level of joint disbond can be quantified using Young Modulus. In this work, the strength of bond is affected by radius of air void within adhesive bond. A high-frequency electromagnetic wave propagated through two joint acrylic glass with acrylate and epoxy adhesive using waveguide adaptor WR90 in conjunction with professional network analyser. This electromagnetic wave is reflected and transmitted at the bond interface due to mismatch impedance at adhesive bond. The output is a dielectric properties that characterizes the bond interface. The increment of Young Modulus leads to increment of dielectric constant and loss factor for epoxy resin and acrylates, respectively.

The effect of natural filler loading, multi-walled carbon nanotubes (MWCNTs), and moisture absorption on the dielectric constant of natural filled epoxy composites was investigated. The natural filled epoxy composites were fabricated using a natural filler, MWCNTs and epoxy resin. The natural fillers chosen were Jute, Kenaf, and Napier. Composites were manufactured using a cold-press method, with the loading of the natural fillers being 7, 14, and 21 vol%, respectively, while the MWCNTs were 0 and 2 vol%. Dielectric tests were conducted using an Agilent/Keysight E8363B PNA Network Analyser in dry and wet conditions. The moisture absorption curves indicate that higher vol% natural filler loading increases the moisture content of the composites. The results show that the Napier filled epoxy composite had the lowest dielectric constant between 12.40 GHz and 16.66 GHz. The presence of 2 vol% MWCNTs successfully decreased the dielectric constant for 7 vol% Jute filled epoxy composites.
