Abstract
Abstract A protective sheet (10) suitable for use in manufacturing an article of clothing or shelter comprises a first layer (12) of soft pliant material which has a low initial tensile modulus of elasticity. Held to the first layer (12) is a second layer (14) of material which is ductile and impermeable to fluids, such as toxic chemicals. The second layer (14) is thinner than the first layer (12) and is preferably composed of metal, metal alloy or a metallic compound. A third layer (16), such as a paint, lacquer or varnish may also be provided to protect the second layer (14) from scratching or corrosion.
