Abstract: A method of manufacturing an article is disclosed which includes an outer fabric material and an inner micro-cellular thermosetting foam plastics material. The method includes facing the outer fabric material, which has been treated on its inner side with a flexible thermosetting plastics material composition, in a mould, closing the mould to define a mould cavity and to deform the fabric material to a predetermined configuration, injecting a foamable flexible thermosetting plastics material composition into the mould, allowing the foamable flexible plastics material to react and completely fill the mould, the pressure of the reaction in the closed spaced of the mould causing the flexible plastics material to bond to the fabric material, allowing the resultant fabric covered micro-cellular foam plastics material to cure, and opening the mould and removing the article.
Abstract: A cut-resistant seat or seating material is disclosed together with methods of forming such a material. The material comprises at least one layer of flexible metal or non-metal matrix material embedded within a compressed flexible foam material. The foam material may be a fire retardant flame material.
