| Abstract Scope |
Elastomeric composites are increasingly recognized as promising materials for thermal insulation applications in building technologies and equipment, owing to their unique blend of mechanical flexibility, thermal resistance, and durability. Utilizing sheet molding compounding (SMC), a versatile and efficient manufacturing method, enables the production of high-performance elastomeric fiber composites. In this study, we focus on formulating vinyl-terminated polydimethylsiloxane (PDMS) composites with either perlite or glass micro-balloons (GMBs) fillers. These formulations are designed to not only provide the necessary rheological properties for SMC processing but also to impart desirable thermo-mechanical characteristics to the cured composites. Our investigation delves into the impact of filler content on the cure kinetics, rheological behavior, and thermo-mechanical properties of the final PDMS composites. Thermal conductivity measurements of the PDMS composites are conducted using both laser-flash and transient plane source (TPS) techniques. Following the selection of a suitable PDMS/filler formulation, we proceed to compound it with recycled glass fibers (rGFs), which are then sheet molded into desired shapes and thermally cured. Through this process, we aim to further enhance the thermal insulation properties of the composites while promoting sustainability through the use of recycled materials. We conclude by analyzing the interplay between process parameters, material structure, and resulting properties in the PDMS composites. |
