Abstract
A composition comprising a liquid-castable polymer system combined with solid particles of a shear thickening additive; an energy absorbing material formed from the composition; and an article comprising the energy absorbing material on a substrate, for example, a glove (1) including the material of the present disclosure as energy absorbing elements (2a, 2b, 2c, 3a, 3b, 3c, 3d, 3e) incorporated onto the surface (4) of a textile substrate to provide protection over the metacarpophalangeal and proximal interphalangeal joints.
Claims20
A method of forming an article comprising a substrate and an energy absorbing material, the method comprising:
- solidifying a liquid composition for use in forming the energy absorbing material while in contact with the substrate, wherein the liquid composition penetrates into the substrate during the solidification, the liquid composition comprising:
- a liquid-castable polymer system, which solidifies to form a material comprising an elastomeric polymer matrix, the material having a Shore D hardness in a range of 30 to 60;
- and
- a shear thickening additive.
An article comprising:
- a substrate;
- and
- an energy absorbing material directly bonded to the substrate, the energy absorbing material comprising:
- a solid elastomeric polymer;
- and
- a shear thickening additive,
- wherein the energy absorbing material has a Shore D hardness in a range of 30 to 60,
- wherein the energy absorbing material penetrates the substrate.
