摘要： PURPOSE:To obtain a molded article with little difference in mechanical strength in the axial direction and in the circumferential direction and enable to stop temporarily feeding of a material to unnecessary parts such as an aperture by arranging a defoaming roller either in front of or back of a material feeding apparatus in the rotating axis direction on the inner face of a cylindrical frame. CONSTITUTION:A defoaming roller D is arranged either in front of or back of a material feeding apparatus C in the rotating axis direction on the inner face of a cylindrical frame A to perform impregnation and defoaming of a cut reinforceing fiber 5 fed from the material feeding apparatus C and a resin compsn. and defoaming is performed while the defoaming roller D is brought into contact with the inner face of the cylindrical frame A and is rotated. In addition, the defoaming roller D is freely rotatably supported on a rotating plate 13 and the rotating plate 13 is rotated in the horizontal direction by rotating a bar 12 for rotation being rotatable in the horizontal direction. In addition, the material feeding apparatus C is not supported by means of the rotating plate 13 and is fixed at the position. Therefore, the feeding direction of the reinforcing fiber 5 and the resin compsn. can be changed in the reverse direction by rotating half the rotating plate 13.

摘要： PURPOSE: To provide a dividing fiber reinforced resin rod-shaped element capable of being easily divided without lowering mechanical strength when the end part of the fiber reinforced resin rod-shaped element is divided to be opened into a wedge shape and a resin is injected into the opened part to fix the rod- shaped element to a structure or a fixing jig. CONSTITUTION: A plastic sheet 2 is preliminarily interposed between the surfaces ready to be divided of the end part of a fiber reinforced resin rod-shaped element 1 in an uncured state and subsequently molded and cured. Since the surfaces between which the plastic sheet 2 is interposed are easily divisible after molding and curing, the end part of the fiber reinforced resin rod-shaped element 1 can be easily divided by small external force.

摘要： PURPOSE:To provide the method for manufacturing a glass fiber-reinforced plastic molding material capable of easily molding a molded form having a complicated shape through pressure molding by specifying the fiber length of a glass fiber chopped strand uniformly scattered on a compound applied on a support film made of a synthetic resin. CONSTITUTION:When a support film 2 made of synthetic resin drawn out of a package 1 wound in a rolled shape is passed in a coater 4, the top face of the support film 2 is coated with a compound 3 is uniform thickness. The synthetic resin support film 2, the top face of which is coated uniformly with the compound 3, reaches a coater 6, and a glass fiber strand 5 is scattered equally on the coating surface of the compound 3. The fiber length of the chopped strand fed must be kept within a range of 3-10mm. Both the chopped strand and the resin are fluidized in response to a mold having a complicate shape in a molding material acquired, and a molded form, various positions of which have equal performance, is formed.

摘要： PROBLEM TO BE SOLVED: To provide a high strength FRP molded article having excellent economical and strength properties by using a multiaxial braided fabric. SOLUTION: This fiber reinforced plastic molded article is constituted of a reinforcing fiber base material having three layers. In this case, both surface layers of the reinforcing fiber base material having three layers are constituted of the multiaxial braided fabric. An intermediate layer is constituted of a reinforcing fiber mat having a bulk density which is smaller than the bulk density of the multiaxial braided fabric. Also, the reinforcing fiber base material of the three layers is formed by a resin transfer molding. The multiaxial braided fabric is either one of a triaxial braided fabric and a tetra-axial braided fabric. The reinforcing fiber mat may be either one of a continuous strand mat or a chopped strand mat.

摘要： PURPOSE:To press a defoaming roller to a resin layer to be defoamed with the desired pressure, move an arm with the desired angle to a resin layer, follow the roller to micro-projections and recesses in the resin layer and prevent the generation of excessive press force by applying proper fluid pressure respectively to a coupled of elastic shrinkable materials and pivoting the arm retaining a defoaming roller. CONSTITUTION:A support 13 mounted at the end of an arm 12 of a robot 11 can be moved along the desired route by means of the arm 12. A pulley 15 is fixed on a rotating shaft 14 rotatably at the end of the support 13, and different pressure is applied to a couple of elastic shrinkable materials 17A, 17B constituted at both ends of a wire rope 16 wound on the pulley. Desired rotation force is imparted on the rotating shaft 14 by the pressure control. Also, a defoaming roller 28 is mounted rotatably around an axis in parallel with the rotating shaft on an arm 27 pivoting integrally with the rotating shaft 14. The defoaming roller 28 can easily move followingly in the recessed and projected form to prevent the generation of excessive press force.
