Abstract

PURPOSE:To prevent the growth of a resin-rich part in the corner of a molding and improve its strength by cutting continuous filament in zigzag fashion and improving the flexibility of reinforcing fiber to a mold. CONSTITUTION:Composite resin sheet 12 consisting of continuous filament 2 mixed with heat-curing resin 11 passes through a press cutter mechanism 14 with plural cutters 13 arranged in zigzag form, and continuous filament 2 is slitted in zigzag way 15. If the resin is formed into a molding with a corner 20, 21 by heat press top force and bottom force 19, 19, reinforcing fiber 18 flexes easily along a curve. In addition, the lop-sided distribution of fiber does not occur during mold clamping on account of the slit 15, and no resin-rich part grows in the corners 20, 21. Thus the strength of the corners 20, 21 is improved.

Used in high places.

る。However, in the conventional composite resin sheet 32 mixed with continuous long fibers 31, the corner portion 35 as shown in FIG.
36, the composite resin sheet 32 has a predetermined bending strength, so that the corner portions 35.
36, the composite resin sheet 32 does not bend along the curvature of Since the movement of both ends of the continuous filament 31 is restricted by the molds 33 and 34, the continuous long fibers 31
Tension is applied to the fibers 31, and the fibers 31 form pores inside the curvature of the corner portions 35 and 36 and on the underside of the protrusion of the molded product 37. As a result, a resin lint portion 38 is generated on the outer periphery of the curvature of the corner portion 35° 36 and above the protrusion of the molded product 37, resulting in a problem that the strength of the corner portion 35° 36 and the protrusion is reduced.

として供し得ない問題がある。On the other hand, a composite resin sheet in which short fibers (25 to 50 fl in length) having a large degree of freedom in the length direction are mixed as reinforcing fibers is also known. When a molded article having the shape shown in FIG. 6 is hot-press molded, the short fibers have a greater degree of freedom in the length direction than the continuous long fibers, so they have excellent conformability to the molding die 33 and 34. Therefore, the formation of resin lint parts 38 at the corner parts 35, 36 and the protrusions is prevented, and the strength of the corner parts 35, 36 and the protrusions is improved. Compared to the molded product 37 used as a molding material, the overall strength is inferior, and there is a problem that it cannot be used as a molding material for molded products used in places where strength is required.

度が向上する。In the above configuration, when the composite resin sheet 12 is molded into a shape having conina parts 20 and 21 by a hot press molding method using a hot press mold 19, 19 as shown in FIG. Since the composite resin sheet 12 is cut in a staggered manner into lengths of 300 to 500 m by the breath cutter mechanism 14 shown in FIGS. 1 and 2, the composite resin sheet 12 Since the bending strength of the sheet is weak, the sheet easily bends along the curvature of the corner portions 20 and 21, so it conforms well to the molding die 19 and 19. Since there is a degree of freedom in the length direction, even if both ends of the reinforcing fibers 18 of the composite resin sheet 12 are restrained by the molding die 19.19 during mold clamping, the fibers will not be unevenly distributed, and the corner portions 20.21 and the molded product will not be unevenly distributed. Unlike conventional resin-rich parts, a resin-rich part is not generated above the protrusion. As a result, the strength of the corner portions 20, 21 and the protrusions is improved.

して供することができる。In addition, since the reinforcing fibers 18 are cut in a staggered manner, compared to conventional composite resin sheets in which continuous long fibers are mixed,
Since the decrease in strength is extremely small and the strength is higher than that of a composite resin sheet containing short fibers, it can be used as a molding material for composite resin molded products used in places where high strength is required.

要求される成形品の成形素材として有効に利用できる０(Effects of the Invention) As explained above, according to the present invention, since the continuous length W4 fibers as reinforcing fibers mixed in the thermosetting resin are cut in a staggered manner, the molding die for the reinforcing fibers is formed. This improves the conformability to curves, prevents the formation of resin-rich areas at curved parts such as corners and protrusions of composite resin molded products, improves the strength of corners and σ protrusions, and improves overall strength. Since the deterioration is extremely small, it can be effectively used as a molding material for molded products that require high strength as a strength member.
