Abstract: An apparatus for the continuous production of an auxetic foam, comprising a tunnel (17) comprising a compression section with an inlet and an outlet for compressing foam in at least one axis as it moves from the inlet to the outlet, means (13, 14, 15, 16) to propel a foam material through the tunnel (17) from the inlet to the outlet, and heating means to heat foam passing through the compression section (11) to a temperature higher than its glass transition temperature.
Abstract: A ceramic amour plate (1,41,50,70) having auxetic reinforcement (2,40,51,71). The auxetic reinforcement may be provided utilising auxetic fibres, auxetic knits or weaves, or lay-ups exhibiting auxetic behaviour. The auxetic reinforcement reduces cracking of the ceramic plate to improve multi-hit performance. The reinforcement may be provided as a layer (2,40, 51) bonded to the surface of the ceramic plate (1,41,50) or as an integral part (71) of the ceramic plate (70).
