Title Method for laminating fiber-reinforced thermoplastic resin prepreg UPDATE_EN meetings
Abstract To provide a method for manufacturing a multi-layered near net shape for a mold product with improved yields of material, strength and rigidity. Prepreg tapes 1 of composite material comprised of thermoplastic resin and reinforced fibers are used to manufacture the near net shape, wherein the prepreg tapes 1 in a same layer are disposed in different directions based on the directions of fibers contained the prepreg tapes 1 and an outer force to be applied to the mold product, and wherein each prepreg tape 1 is placed and stitched by a suitable stitching method.
(From EP2554348 A1)
Outline of related art and contending technology BACKGROUND ART
Continuous reinforcing fibers impregnated with thermoplastic resin to the fiber reinforced thermoplastic prepreg tape of each layer and each layer are arranged in a predetermined direction by making the direction of the reinforcing fibers are laminated, by integrally stitching multiaxially laminated sheet is produced with the processes, the multiaxial laminated sheet is cut or laminated to be installed in a mold into a predetermined shape and to reshape the shaping step, the shaping of the intermediate into a predetermined shape is disposed within a mold installation step, the intermediate body is disposed within a mold in the installed intermediate step press and fiber reinforced thermoplastic composite material is heated to a temperature higher than the melting point of the thermoplastic resin after molding, the thermoplastic resin is cooled to a temperature lower than a melting point of the fiber reinforced thermoplastic composite molding step of a method of molding material is disclosed (e.g. see Patent document 1).
In addition, the invention of Patent document 1 is, in a state where the laminated sheet or laminated sheet stitching is reshaped into the predetermined shape is performed in a state.
Fiber reinforced plastic composite material was prepared in the predetermined shape can be guided by, the reinforcing fibers on a substrate by using the shape of the composite to be manufactured is determined depending on the required properties and the like to any desired site a plurality of directions of the reinforcing fiber material and having any desired orientation so that the processed amount of the embroidery and, in the shape of the embroidery is needed from a base material of the male part (non-puncture) was removed and the consumer, a core material which is then hand lay up method of a general method such as fiber reinforced plastic composites is the method for molding has been disclosed (e.g. see Patent document 2).
Scope of claims [claim1]
1. (A hologram) based on the sheet or on the layer already formed thereon, the fiber reinforced thermoplastic resin prepreg tape at any position in any direction and carried out with an adhesive and stitching, cut to a length of any one of the fiber reinforced thermoplastic resin prepreg tape sewn in order to complete the procedure a fiber reinforced thermoplastic resin prepreg tape attached to the sewing procedure, from an arbitrary position in each layer and then, wherein the fiber reinforced thermoplastic resin prepreg tape sewn to repeat a sequence sequentially in a fiber reinforced thermoplastic resin prepreg tape is sewn to form a planar shape of one layer, then the further layer on top of the planar shape of the fiber reinforced thermoplastic resin prepreg tape layer attached to the sewing and stacking formed according to the procedure, the planar shape of a next layer while forming a predetermined shape to produce multilayer structure according to the near net shape molded article having the formed by sewing (near net shape) of the fiber reinforced thermoplastic resin prepreg lamination method.

[claim2]
2. Method according to claim 1, the required strength of the molded article (strength) and rigidity (stiffness) includes an arrangement of a fiber reinforced thermoplastic resin prepreg tape as a method of performing, in the direction of the article molded by the tensile forces on the fibers of the fiber reinforced thermoplastic resin prepreg tape with the arrangement direction is provided to match the site placement method, wherein the article molded by the tensile forces on the direction of the fiber reinforced thermoplastic resin prepreg tape fibers are positioned perpendicular to the arranging direction does not cause the placement site, arranged adjacent to two other fibers 2 in the direction of the abutment portion of the fiber reinforced thermoplastic resin prepreg tape at the site of the same layer in the gap, and/or the lower abutment portion adjacent the top of a prepreg tape is extended over the fiber reinforced thermoplastic resin prepreg tape placed at the placement method of at least one of the one or a plurality of layers in a method in a layer applied to the fiber reinforced thermoplastic resin of the prepreg lamination method.

[claim3]
3. Method according to claim 1 or 2, the required strength and rigidity of the molded article so that as a method of performing a stitching, to be susceptible to delamination at the site of the sewing thread a site susceptible to deformation possible even in a concentrated manner in the stitching fiber reinforced thermoplastic resin prepreg lamination method.
