In a method for molding a sheet which includes thermosetting resin materials reinforced with glass fiber or carbon fiber, the sheet includes a covering film always existing in a side which is not in contact with a mold face and, when the sheet and covering film are shaped along a mold face and the sheet is thermally cured, apparatus for dealing with an accidental breakage of the covering film is arranged on the side of the sheet which is covered by said covering film.

Method for molding fiber-reinforced resin

This invention provides a sheet for molding a fiber-reinforced resin finishing the fiber-reinforced resin moldings surface under an excellently colored condition. A sheet for molding of this invention comprises a fiber-reinforced resin layer and a colored surface resin layer being laminated and has, in the fiber-reinforced resin layer, a fiber-reinforced colored resin layer adjacent to said surface resin layer and colored in a color similar to that of the surface resin layer, and a fiber-reinforced transparent resin layer arranged on a surface in a side reverse to the surface resin layer and having a curing character by ultraviolet rays.

Sheet for molding fiber-reinforced resin

The method for molding a resin reinforced with fiber wherein a resin sheet reinforced with fiber is positioned juxtaposed a face of a mold, which is either one of a female mold or a male mold, and then hardened, but before molding, modifying the viscosity to different levels in different portions of the resin sheet. Thus, it is possible to surely prevent occurrence of a partial difference in thickness of the moldings or, if necessary, to partially change these thicknesses according to predetermined values.

Method for molding resin reinforced with fiber and moldings produced

A thermosetting resin composition of highly satisfactory storage stability comprises 100 parts by weight of a thermosetting resin composition, 0.0001 to 2.0 parts by weight of a thiuram compound possessing at least one atomic group represented by the following formula: ##STR1## wherein p stands for an integer in the range of 1 to 8, and 0.00001 to 0.1 part by weight (as copper metal) of a copper-containing compound.

Resin composition of high storage stability

An electric metal foil-plated laminate sheet which is obtained by laminating a cured layer of a thermosetting resin composition with electroconductive foils, said thermosetting resin composition comprising 30-85% by weight of (A) a rubber-modified vinyl ester obtained by reacting,

Laminate with layer of rubber-modified vinyl ester and unsaturated

Curable resin composition with a thiuram and a copper compound as

A method for improving storage stability of a thermosetting resin, which comprises adding a thiuram compoound to the thermosetting resin comprising a reaction product of an epoxy resin with an .alpha.,.beta.-unsaturated monocarboxylic acid dissolved in a polymerizable olefinic unsaturated compound, said thiuram compound having in one molecule thereof at least one atomic group expressed by the following general formula I: ##STR1## wherein p is an integer of 1 to 4, and being used in an amount of 0.0001 to 2.0 parts by weight per 100 parts by weight of said reaction product.
