Investigation of Thermal Properties of Vertically Reinforced Piezo Fuzzy Fiber-Reinforced Composites

This study investigates the impact of wavy carbon nanotubes (WCNTs) on the thermal properties of a piezoelectric (PZT) fiber, aiming to develop a novel structure termed as piezo fuzzy fiber-reinforced composite (PFFRC), where the WCNTs are grown radially on the piezoelectric fiber. Employing the micromechanical models, the Method of Cells and the effective medium, the research aims to estimate the coefficient of thermal expansion and thermal conductivity of the PFFRC. Prior to analysis, the study intends to characterize the influence of WCNTs on the thermal properties of PFFRC. Subsequently, analysis is conducted to understand potential temperature-dependent variations in thermal properties and assess the effect of increasing the fraction of PZT fiber on the composite’s thermal behavior. Additionally, the study aims to determine the effect of thermal interfacial resistance acting at the WCNT/polymer interface, on the estimated thermal properties of the PFFRC. This research contributes to the advancement of composite materials for aerospace applications by investigating the thermal properties of piezo fuzzy fiber-reinforced composites. The study provides insights into how wavy carbon nanotubes and piezoelectric fibers can enhance thermal management and structural integrity in demanding environments, supporting the development of future aerospace systems.
