Abstract: A pressure impulse mitigating barrier including a crosslinked gel, the gel including water and gelatin which has been crosslinked using a functional silane compound, the compound including an electrophilic group (where the electrophilic group is not a silane) and a group of formula (B) where R is a C1-10 alkyl group, C6-10 aryl group, or C7-12 arylalkyl group; R? is a C1-10 alkyl group, C6-10 aryl group, or C7-12 arylalkyl group; n is 0-1, and where the functional silane has Mw of 800 g/mol or less.
Abstract: Described herein are armour panels that can be used to protect entities such as vehicles, buildings or organisms from overpressure either in the form of an explosion (shockwave) or projectile (bullet, shrapnel etc). In particular, the invention relates to the use of a combination of layers to form a panel with pressure impulse mitigating properties to provide an armour panel which is lightweight, cheap to manufacture and yet strong enough to withstand impact from high velocity ballistics, fragments and the like.
Abstract: A multilayer armored panel comprising: (I) at least one layer that is non moldable when dry but moldable when wet; (II) at least one hydrogel based layer in contact with layer (I) which, when wet enables the molding of layer (I) but which is capable of drying out to leave a non moldable layer (I).
