Abstract

Flexible composites from high performance fibres were developed and targeted to replace the wall of existing rigid ceramic Particulate Filters. The composites are made from E Glass fibre webs of different density in the middle, with standard SiC Ceramic fibres webs in in the outer layers, forming a sandwich structure. Different needling densities were applied to form nonwoven composites, and they were stitched diagonally on the surface at specified intervals with continuous glass fibre filament yarn. In total, nine novel flexible composites were developed and evaluated for their structural, surface, mechanical and thermal properties. Based on the results and statistical analysis, the B2 sample is considered to be taken for further research to develop Particulate Matter (PM) filters.
