Assessing The Efficacy of Different Fabric in Enhancing Flame Retardancy of Recycled Fabric Panels

This study investigates the use of recycled fabrics, particularly cotton and Nomex composites, as reinforcing fabric in fire-resistant composite panels. Samples were taken through successive changes in the ratio of Nomex fibres concerning cotton, after which they were bonded in the matrix with polyester resin. The obtained composites were characterised by carrying out horizontal and vertical burning tests (those according to ASTM D635 and ASTM D3801, respectively), and by the compressive test (according to ASTM E72) conducted by using the GOTECH machine. The findings showed that the panels with 100% contents of Nomex had lower burning rates at 10.59 mm/min, and they retained the high compressive strength average at 46.6 Mpa. The samples having a Nomex proportion of at least 50 % showed significant improvements in the protection against fire as well as structural stability. The use of recycled fabrics aligns with sustainable material innovations by reducing textile waste, lowering embodied energy in construction and contributing to environmentally responsible design practices.
