Biomorphic and Auxetic Textile Architectures
topic
Auxetic textile structures with negative Poisson ratio that expand laterally under longitudinal tension are investigated for firefighting clothing applications where conventional fabrics thin at high-stretch areas reducing thermal protection at joints, with auxetic structures maintaining or increasing thickness under stretch preserving insulation value during firefighting movement, while biomorphic designs inspired by biological protective systems including fish scale-inspired interlocking elements are explored for combined flexibility and puncture resistance.
Role
Represents structural textile architecture innovation that could address the performance degradation under physical deformation that affects conventional firefighting clothing fabrics, with auxetic structures potentially eliminating the protection reduction at high-strain body locations during movement that is a recognised limitation of flat-constructed composite systems, providing more uniform protection across the body surface through all firefighting movement positions.
