Gold Medal Smart impact protective 3D-spacer fabrics of adaptive stiffness

Principal Investigator: Dr Hu Hong, Institute of Textiles and Clothing

To dissipate impacts during sports, the Institute of Textiles and Clothing and the Hong Kong Research Institute of Textiles and Apparel have co-developed a smart impact protective fabric that can be used for energy absorption and impact spreading.

The smart impact protective material is made of three-dimensional auxetic spacer fabric treated with impact hardening polymer that was specially developed based on smart stress-responsive micro-gels. The treated fabric remains soft in normal use but becomes rigid instantly on impact to maximally absorb and dissipate the impact energy. It turns soft again after impact.

This fabric offers high impact protection and excellent comfort due to high air permeability and flexibility. It is washable, making use and care easy, and it can be tailored to any size and shape. Taken together, these features mean that the fabric is a convenient substitute for the polyurethane foams and rubber that are currently used to produce high-performance protective garments and equipment.
