摘要： A process for producing a thick reinforced plastic article by laminating unit layers of a molding material composed of a thermosetting resin and a reinforcing material, which comprises scattering fibers on the surface of an earlier disposed unit layer while it is in the uncured state, then curing the unit layer, and laminating the next layer on the cured unit layer.

摘要： A pipe joint of a reinforced resin having a structure in which the wall of at least a socket portion consists of an inside surface layer composed of a cured product of a reinforced resin molding material, an outside surface layer composed of a cured product of a reinforced resin molding material, and an interlayer between these layers composed of a cured product of a resin mortar. The above pipe joint can be molded by (1) forming an uncured inside surface layer composed of a resin-impregnated reinforced molding material on the peripheral surface of a core mold; (2) coating a resin mortar on the inner surface of a split mold and molding the surface of the coated resin mortar by a former having a contour substantially corresponding with that of the inside surface layer; (3) forming an incompletely cured interlayer composed of resin mortar by capping the split mold containing the molded resin mortar on the inside surface layer and removing the split mold after the curing of the resin mortar has proceeded to a certain extent; (4) forming an uncured outside surface layer composed of a resin-impregnated reinforced molding material on the peripheral surface of the incompletely cured interlayer; and (5) completing the curing of all the layers. Alternatively, a cured cylindrical structure prepared separately may be used as the inside surface layer instead of forming it in situ in the above process.

摘要： A mold for the production of a reinforced plastic tubular body having an annular groove such as a pipe coupling, the mold having a mold body and detachably mounted on a predetermined position thereof, an annular groove former consisting of a surface layer of an elastic material and a core covered with the surface layer. The reinforced plastic tubular body is produced by forming a layer of a molding material around the aforesaid mold, curing the layer of molding material, separating the mold body from the cured layer of molding material, and then separating the annular groove former from the cured layer of molding material by removing the core and then removing the surface layer.
