Thermo-acoustic Insulation Textiles for Automotive

Project No.: RP04555G : The project encompasses research on a range of ceramic and natural fibrous materials for thermal and acoustic attenuation in automotive applications. To address the issue of fibre dust emission from exhaust systems, hybrid materials are utilised, primarily composed of knitted fabrics, nonwovens, and continuous fibre masses. Incorporating industrial glass-roving waste as a filler material contributes to waste management efforts and reduces fibre dust emissions from exhausts. A novel test setup, developed and patented, has been created to simulate the exhaust environment for acoustic measurements. The project also investigates various natural fibrous materials for thermo-acoustic insulation within the passenger compartments of vehicles. Highlight: • Optimized thermo-acoustic insulation • Glass-roving waste management • Hybridization for life and performance enhancement • Exhaust-system simulated environment tested
