Predicting Adhesive Bond Performance Based on Initial Dielectric Properties

Abstract: In recent years, there has been a widespread growth in the application of composite materials particularly in the Aerospace and Automotive sectors. This is because composite structures are generally comparatively light in weight and provide corrosion and wear resistance as compared to metals or ceramics. Due to the strict fail-safe philosophy of the aerospace industry, the certification approach for current practice in joining composite materials is to thicken the joining areas and to use numerous fasteners wh… Show more

“…To assure high-speed signal transmission and low signal transmission loss, the dependence of the dielectric properties on the frequency is plotted in Figure S3 and Figure . The polarization response of the polymer material to the electric field frequency shown in Figure d indicated dielectric properties and their regions of interfacial and space charge, orientation, atomic (ion), and electronic polarization . For the nonpolar cross-linked polybutadiene adhesive system, the polarization strength of vinyl with isolated π electron played an important role at the high-frequency electric field.…”

“…As shown in Figure S27 and Table , the dielectric constant values display dependence on the measurement frequencies. Generally, there are four polarization types (i.e., interfacial and space charge, orientation, and atomic (ion) and electronic polarization) . The polarization mechanisms have their corresponding effective frequency ranges.…”

“…Advanced super-high-frequency communications can satisfy the future demand for faster internet connections and increased device access. However, mutual interference easily occurs during super-high-frequency transmission, leading to a resistance–capacitance time delay, an increase in crosstalk, and more energy consumption. , As shown in eq , the signal transmission speed ( V ) is inversely proportional to the square root of dielectric constant ( k ) value of the polymeric materials: , where c is light speed. Furthermore, the signal propagation loss rate ( L ) is proportional to the frequency ( F ), dielectric loss (tan δ, f ), and square root of k (eq ): , where the prefactor K is a constant.…”

“…One of the most remarkable capabilities of the dielectric material state determination method is to detect and predict the strength of bonded materials, especially the strength of bonded heterogeneous materials. Banerjee, et al have pioneered this method development, and much current research is underway in our group [10]. This topic deserves much more space that we have in this discussion, but an example of the capabilities will be provided.…”
