| abstract |
The invention relates to a laminar structure ( 10 ) providing adaptive thermal insulation, comprising a first layer ( 22 ), a second layer ( 24 ), at least one cavity ( 16 ) provided in between the first layer ( 22 ) and the second layer ( 24 ), a gas generating agent ( 18 ) having an unactivated configuration and an activated configuration, the gas generating agent ( 18 ) being adapted to change from the unactivated configuration to the activated configuration, such as to increase a gas pressure inside the cavity ( 16 ), in response to an increase in temperature in the cavity ( 16 ), the first layer ( 22 ), the second layer ( 24 ) and the cavity ( 16 ) being arranged such that a distance (D) between the first layer ( 22 ) and the second layer ( 24 ) increases in response to the increase in gas pressure inside the cavity ( 16 ). |
