Abstract
Official abstract text for this publication.
The present invention provides a laminate that can maintain sufficient strength even after combustion and that can reduce a strength decrease due to flame and heat caused by ignition inside a battery especially when the laminate is used as a cover for an in-vehicle battery. Provided is a laminate including: a base layer containing a resin and a fiber; and a sintering layer containing a thermoplastic resin and a sintering promoter.
First claim
Opening claim text (preview).
1 . A laminate comprising: a base layer containing a resin and a fiber; and a sintering layer containing a thermoplastic resin and a sintering promoter. 2 . The laminate according to claim 1 , having a rate of change in bending modulus of 99.7% or less after being heated for three seconds with flame caused by ignition of a lithium-ion battery, the rate of change in bending modulus being represented by the following formula (3): (Rate of decrease in bending modulus)=[(Bending modulus before heating)−(Bending modulus after heating)]/(Bending modulus before heating)×100 (3). 3 . The laminate according to claim 1 , wherein the base layer has a bending modulus of 10 GPa or greater. 4 . The laminate according to claim 1 , wherein the fiber is at least one selected from the group consisting of a glass fiber and a carbon fiber. 5 . The laminate according to claim 1 , wherein the resin has a loss on heating at 400° C. of 30 to 80% by mass. 6 . The laminate according to claim 1 , wherein the sintering promoter constituting the sintering layer is a Lewis acid catalyst.
