Abstract
The present invention provides a laminate that has excellent flame-shielding performance and heat-shielding performance and can reduce the transmission of flame and heat generated by ignition inside a battery to the outside, especially when used as a cover for an in-vehicle battery. Provided is a laminate including: a fiber layer including a resin and a fiber; and a thermal insulation layer formed on at least one surface of the fiber layer.
Claims12
A laminate comprising:
- a fiber layer including a resin and a fiber;
- and
- a thermal insulation layer formed on at least one surface of the fiber layer, wherein the laminate has a thermal conductivity after heating at 800° C. for one minute of 0.01 to 0.15 W/mK, and
- the resin constituting the fiber layer has an oxygen index of 20 or greater.

A laminate comprising:
- a fiber layer including a resin and a fiber;
- and
- a thermal insulation layer formed on at least one surface of the fiber layer, wherein a rate of change of thermal conductivity after heating at 800° C. for one minute, represented by the following formula (1), is 1 to 10:
- (Rate of change of thermal conductivity)=[(Thermal conductivity before heating)−(Thermal conductivity after heating)]/(Thermal conductivity after heating) (1).
