An instrument panel unit () includes an instrument panel () and a decorative sheet (). The instrument panel () includes a sticking portion () and an exposed portion (). A plurality of insertion groovesand insertion holesare formed alternately at an end on a rear side of the sticking portion (), into which bent pieces () formed at a rear end of the decorative sheet () are inserted. A groove front-surface () forming the insertion groove () of the instrument panel () is formed in a tapered shape such that a width between the groove front-surface and an opposing groove rear-surface () gradually increases upwardly. The bent piece () is formed to be thinner than the groove width at the upper part serving as the entrance part of the insertion groove () and to be thicker than the groove width of a groove bottom-surface ().

A fiber-reinforced composite material and a method for manufacturing the same. A first binder resin is applied to a first portion for forming a deformed part of a fiber base material, and a second binder resin is applied to a second portion excluding the first portion. The fiber base material is then heated so that the degree of melting of the first binder resin during shaping is less than the degree of melting of the second binder resin, and the second binder resin is softened. Shaping is then performed so that a deformed part is formed in the fiber base material, and a preform is obtained. A fiber-reinforced composite material is obtained using the preform as a molding precursor.

A molded resin laminate in which the dimensional accuracy and the strength are excellent at a bent portion and a method for producing the same are provided. One, in which an average diameter of small cells existing in a region on a side of a resin cover to be formed into a surface layer is smaller than an average diameter of large cells existing in a region on a side of a base resin component to be formed into a base layer, is used as a foamed resin component to be formed into an intermediate layer of the molded resin laminate. After the base resin component is molded with a molding machine, the base resin component is held on a male mold of a forming machine different from the molding machine described above. A sheet-shaped laminate, which is obtained by joining the foamed resin component and the resin cover, is arranged between the base resin component and a female mold. Subsequently, the forming machine is subjected to mold clamping. The sheet-shaped laminate and the base resin component are joined to one another in a cavity, and the gas in the cavity is vacuum-evacuated to thereby form the sheet-shaped laminate.

Method for producing a molded resin laminate

A resin mold has a surface layer formed on the molding surface of a main body from a thermosetting resin and containing fine particles of silicon carbide. The surface layer can be formed simply by thermosetting the resin without calling for any plating, so that the mold can be made in a short time. The high hardness of silicon carbide gives a high wear resistance to the surface layer. The main body is formed from a thermosetting resin and contains metal particles.

Resin mold

A vacuum covering method for covering a profiled surface of a base member with a sheet by effecting bonding between the sheet and the base member under vacuum, wherein the base member has a multiplicity of spaced vacuum grooves extending across the profiled surface. When air is evacuated from the vacuum grooves, the sheet is drawn by vacuum or suction down onto the profiled surface. The base member is injection-molded of synthetic resin and undergoes thermal shrinkage when it becomes cool after molding. With the vacuum grooves provided in the profiled surface, thermal shrinkage is distributed uniformly over the entire area of the profiled surface and does not generate shrink mark which may form a depression on a front surface of the sheet bonded to the base member.

A vacuum forming apparatus has a first mold and a second mold, the first mold including a forming surface. The first mold has a hollow space defined therein and communicating with the forming surface through holes defined in the first mold. The hollow space is connected to a vacuum pump for developing a vacuum in the hollow space to attract a sheet against the forming surface through the holes. The second mold has a presser including a cylinder which displaces a cutter having a serrated trimming blade of the second mold. The presser has an upper groove which accommodates teeth of the serrated trimming blade. The first mold has a lower groove for receiving the teeth of the serrated trimming blade when it is displaced downwardly by the cylinder.
