A process for the preparation of thermoplastic auxetic foams comprising the steps of: a) taking conventional thermoplastic foam; b) subjecting said foam to at least one process cycle wherein the foam is biaxially compressed and heated; c) optionally subjecting the foam to at least one process cycle wherein the biaxial compression is removed and the foam mechanically agitated prior to reapplying biaxial compression and heating; d) cooling said foam to a temperature below the softening temperature of said foam; and e) removing said compression and heat.

Process for the preparation of auxetic foams

A composite material comprises a layer of fibres conjoined to a matrix, where one of the matrix and fibres comprises a first component which exhibits auxetic behaviour for loading along a first direction, and the other of the matrix and fibres comprises a second component which exhibits non-auxetic behaviour for loading along the first direction.

Composite material

A garment is provided that has a support region and a foam pad at the region. The foam pads has at least one auxetic foam layer. A garment is also provided that includes at least one auxetic foam layer.
