Title:
LAMINATE
Document Type and Number:
Japanese Patent JP2021098321
Kind Code:
A
Abstract:
To provide a new structure which is hardly broken.SOLUTION: A laminate 1A has a body portion 9 in which an uppermost layer 3, an intermediate layer 5 and a lowermost layer 7 are laminated in this order. The intermediate layer 5 has one or more low Young's modulus layers 11 having Young's modulus that is lower than that of the uppermost layer 3 and lower than that of the lowermost layer 7. The Young's modulus (GPa) of the low Young's modulus layer and the Young's modulus (GPa) of the uppermost layer satisfy the following expression (1), and the Young's modulus (GPa) of the low Young's modulus layer and the Young's modulus (GPa) of the lowermost layer satisfy the following expression (2). Expression (1): Young's modulus of low Young's modulus layer≤Young's modulus of uppermost layer×0.8. Expression (2): Young's modulus of low Young's modulus layer≤Young's modulus of lowermost layer×0.8.SELECTED DRAWING: Figure 1
