Abstract: Provided is a sheet-shaped mold possessing a high strength and having a low breakage rate in demolding even in a case where the mold is thin and has a large-area. The sheet-shaped mold is prepared by combining a cured silicone rubber containing a polyorganosiloxane and a fiber for reinforcing the cured silicone rubber. The fiber may comprise a cellulose nanofiber. The sheet-shaped mold may have an uneven pattern on at least one surface (or side) thereof. The fiber may be surface-treated with a hydrophobizing agent. The fiber may forma nonwoven fabric, and the nonwoven fabric may be impregnated with the cured silicone rubber. The cured silicone rubber may comprise a two-component curable silicone rubber having a polydimethylsiloxane unit. The sheet-shaped mold may be a mold for nanoimprint lithography using a photo-curable resin.

Abstract: Provided is a sheet-like prepreg that has both a low coefficient of linear thermal expansion and high flexibility and offers excellent anti-warpage performance and cracking resistance. The sheet-like prepreg according to the present invention includes a curable composition and a sheet-like porous support impregnated with the curable composition. The sheet-like porous support is made from a material having a coefficient of linear thermal expansion of 10 ppm/K or less. The sheet-like prepreg gives a cured product having a glass transition temperature of −60° C. to 100° C. The curable composition includes one or more curable compounds (A) and at least one of a curing agent (B) and a curing catalyst (C). The curable compounds (A) include an epoxide having a weight per epoxy equivalent of 140 to 3000 g/eq in an amount of 50 weight percent or more of the totality of the curable compounds (A).
