Patent ID: 8444798

Claim:
A hot-press cushioning member used between an object to be compressed and a hot platen when the object, which is a stack of a plurality of laminated plate materials, is subjected to press forming by the application of heat and pressure to manufacture a laminated plate, said hot-press cushioning member comprising: a fiber-rubber composite material layer made of a web and rubber impregnated in said web, wherein said fiber-rubber composite material layer contains voids, an amount of compressed thickness deformation (a) is obtained by subtracting a compressed thickness (H 2 ) of the hot-press cushioning member under a predetermined press-forming pressure from an initial thickness (H 1 ), an amount of restored thickness deformation (b) is obtained by subtracting said compressed thickness (H 2 ) from an uncompressed thickness (H 3 ) of the hot-press cushioning member with said press-forming pressure released, and the (a:b) ratio ranges from 1:1 to 1:0.8 and said web is woven fabric made of texturized yarn.
