A Study on the Thermal Interface Mechanisms of Natural Fiber/Fillers and Allotrope-Based Polymers 2023-01-5129

Composites of polymers reinforced with synthetic/natural fibers are mainly used in engineering sectors such as automobiles, aerospace, and in household appliances due to their abrasion resistance, high toughness, strength, and high specific modulus. The purpose of this research is to provide an overview of fiber-matrix interfaces and interface mechanism that leads to enhanced properties. This article investigates how natural/synthetic fibers, mineral based-materials and additional allotropic materials work rapidly and effectively across interfaces. The objective of this work is to discuss different interfacial mechanisms (i.e., diffusion, chemical bonding, and mechanical crosslinking) of fiber reinforced polymers and to understand the mechanism of heat transfer in hybrid polymers by establishing the polymer morphology, chain structure, and interchain linkages to allow molecular interactions between the material phases and to determine the characteristics and thermal conductivity of composites made of polymers. It is established that the fiber/filler interaction with various concentration, fiber orientation, alignment, filler content fraction, size of filler, usage of conducting fillers determines the thermomechanical properties that ensure maximum thermal conductivity of the interfacial material.
