摘要： PURPOSE:To carry out fully automatically lamination of a composite material, by transferring a sheet to a position where it is dropped on a mold, cutting it, molding it under pressure by using a press mold for sheet molding and then lowering the next sheet. CONSTITUTION:A prepreg sheet 56 sucked on a surface plate 35 of a bed is press-cut by means of a sheet cutting knife 12 attached on the lower face of an elevating and lowering plate 11 and sucked by means of a sheet sucking plate 41 after cutting and transferred, and the cut sheet is inserted in a hole 49 on a mold 22. Then, the elevating and lowering plate 11 is lowered and the prepreg sheet 56 is press-cut by means of a sheet cutting knife 12. The cut sheet on the mold 22 is molded under pressure by means of a press mold 13 for molding formed with an elastic body. Then, after cutting and press- molding of the prepreg sheet 56, the elevating and lowering plate 11 is returned to a stand-by position.

摘要： PURPOSE:To prevent a sheet from adhering on an embossing mold, by forming a fluid layer between a molding surface of the embossing mold and a surface of a molded sheet when the embossing mold is retreated after molding by means of the embossing mold. CONSTITUTION:A mold 12 is coated with a releasing agent and a sheet 13 such as a prepreg sheet placed thereon. Then, an embossing mold 11 for sheet lamination is lowered and its molding surface 3 is pushed under pressure on the mold 12. Then, transferring of the embossing mold is stopped, and a fluid such as air is supplied under pressure from a fluid supplying line 10 to flow a fluid between the molding surface 3 and a molded sheet 13 from a port 7. At the same time, a fluid supplying and discharging line 5 is opened to discharge under vacuum a fluid in an elastic hollow container 2 and to make the deformation into a recess of the molding surface 3 easy. A fluid layer 16 flowing in the outer circumferential direction is formed between the molding surface and the molded sheet 13, and no adherence of the sheet 13 occurs on the molding surface 3 at the time of peeling.

摘要： PURPOSE:To make it possible to machine the joint areas with high straightness with respect to a cylinder by a method wherein the deformation of a fiber reinforced plastic (FRP) bellows joint by external force is eliminated at machining by securing the joint in position by means of a core. CONSTITUTION:After a core 10 is inserted in a FRP bellows joint 2 the inner diameter of which is slightly larger than the outer diameter of an outer pipe 11 in such a manner that respective rounded projections 16 positionally correspond to the cylindrically straight parts 3 and 3, which are formed at the corrugated part of the joint 2, pressurizing fluid is introduced into a pressure application chamber 13 so as to diametrically expand the outer pipe 11 in order to bring the rounded projections 16 into close contact with the inner surfaces of the cylindrically straight parts 3 and 3. Next, the pressure in the pressure application chamber under the above-mentioned closely contact state is held by a pressure holding means 19. After that, the core 10 is rotated by being supported on shafts 15 in order to machine the joint areas (a) and (b) of the cylindrically straight parts 3 and 3 with respect to a straight tube by employing the core as the datum. Accordingly, after machining the surface (a) is parallel to the joint reference axis O of the straight tube and the surface (b) is held normal to the axis O.

摘要： PURPOSE:To enable stable manufacturing by mitigating tensile stress drastically, by a method wherein an inner layer skin molded on a winding mold is shifted on a processing mold whose diameter is slightly larger than that of the winding mold and a core material is stuck to the external circumference. CONSTITUTION:An inner layer skin 1 molded on a winding mold A through a filament winding (FW) method is shifted onto a processing mold B whose diameter is slightly larger than that of the winding mold by removing the inner layer skin 1 from the winding mold and a form of the outside of the same is shaped through machining. Then a core material molded beforehand is stuck to the external circumferential surface of the skin 1 and a form of the external circumferential surface of a core 2 is shaped through machining. As for a laminate whose dimensions of the outside diameter of the core 2 has been shaped, winding, curing and molding of an outer layer skin 3 based on the FW method are performed on the external circumferential surface of the core 2 by either shifting the same to the winding mold A by removing the same once from the processing mold B or leaving the same on the processing mold B as it is and the external circumferential surface of the skin 3 is machine. With this construction, mitigation effect on tensile stress can be obtained. A crack is not generated on a foam.

摘要： PURPOSE:To make the thickness of formed product constant, eliminate mixing of bubbles in the corners of the product, increase the fiber content and improve the quality of the shape by winding continuous fibers, impregnated with resin, around a cylindrical mold. CONSTITUTION:The cylindrical core mold 1 is inserted into an elastic pipe 2, formed by an elastic body such as rubber or the like, while a filament layer 3 for forming FRP, whose continuous fibers consisting of glass fibers, carbon fibers or the like are impregnated with resin, is formed around the outer peripheral surface of the elastic pipe 2. Next, the core mold 1 is pulled out of the elastic pipe 2 and a corner mold 6, having an outer profile corresponding to the inner corners of the shape such as a channel, an angle or the like, is inserted into an auxiliary elastic pipe 7, arranged at the outer peripheries of the corners and made of an elastic body such as rubber or the like. Then they are loaded into a forming mold 8. An internal pressure is applied to the elastic pipe 2 through the auxiliary pipe 7 to expand forcibly the elastic pipe 2 in the forming mold 8 together with the filament layer 3 and, thereafter, the resin in the filament layer 3 is heated to cure it. Subsequently, the square pipe, obtained by this method, is divided horizontally into two parts along the lengthwise direction thereof.

CONSTITUTION:The continuous fibers 2 are pulled out of a supply 1, batching the continuous fibers 2 of glass fibers, carbon fibers or the like, and are passed through a powder coating unit 3. In the powder coating unit 3, the resin matrix 4, powdered previously, is injected against the continuous fibers 2 and whereby the powder of resin matrix 4 adheres to the surface of the continuous fibers 2. Subsequently, the continuous fibers 2 are heated by a heater 5 and are wound around a mandrel 6 through a traverse 7. The fibers are heated and formed by pressure after winding and whereby voids can be removed and the performance of the FRP may be improved. On the other hand, polyether etherketone resin may be employed specially for the resin matrix 4 employed for this method.

摘要： PROBLEM TO BE SOLVED: To obtain a product having no sticking at a cooking by a method wherein a molded matter is molded by pouring a resin material between a fluororesin film stuck on an inner die and the inner surface of an outer mold so as to demold the resin molded matter integral with the fluororesin film from the inner and outer dies. SOLUTION: As the material of a die no special limitation is present and generally a metal excellent in a heat resistance such as iron, stainless steel, aluminum, aluminum alloy or the like is employed. On the surface of the inner die 1, a fluororesin film 4 is formed. In addition, in order to realize the easy demolding of the fluorine film from the surface of the inner die 1, a releasing treatment is applied to the surface of the inner die 1. As one of the releasing treatment, a ceramic releasable film 3 is formed on the surface of the inner die 1 and then the fluororesin film 4 on the film 3. In addition, the application of the releasing treatment or the formation of the ceramic releasable film 3 on the surface of the outer mold 2 is also preferable.
