FLEXIBLE MATERIAL

摘要

FIELD: mechanical engineering. SUBSTANCE: flexible material has at least two different layers with different thermal expansion coefficient. One of layers is made of plastic. Non-straight slot in made in material. When temperature comes out of definite limits, deformation of material takes place with change of area of slot. Material is good for packing, binding and other barrier members to provided ventilating regulation. EFFECT: enlarged operating capabilities. 23 cl, 6 dwg
