Embodiment Construction

[0041] The present invention is a joined body produced by vibration welding as follows:

[0042] A reinforcement having at least one irregular layer in which chopped carbon fibers are irregularly oriented in a thermoplastic resin and at least one layer of unidirectional material in which continuous carbon fibers are unidirectionally aligned in a thermoplastic resin (the same as or different from said thermoplastic resin contained in said irregular layer); and

[0043] A reinforced member having an open cross-sectional shape, the reinforced member having irregular layers (chopped carbon fiber and thermoplastic resin may be the same as those contained in said irregular layers of said reinforcing member or different) and at least one selected from the group consisting of unidirectional material layers (continuous carbon fibers and thermoplastic resins may be the same or different from those contained in said unidirectional material layers of said reinforcement), wherein

Abstract

Provided is a joined body wherein a reinforcing material having at least one layer of each of a random layer, wherein a chopped carbon fiber is randomly oriented in a thermoplastic resin, and a unidirectional material layer, wherein a continuous carbon fiber is disposed unidirectionally arranged within a thermoplastic resin, has been vibration-welded, in a manner so as to produce a hollow closed cross section, to a material to be reinforced that is open cross section and has at least one layer selected from the group consisting of the random layer and the unidirectional material layer.

Description

technical field [0001] The present invention relates to a carbon fiber reinforced composite material joined body produced by vibration welding of a reinforcing member having a layer structure containing carbon fiber and thermoplastic resin and a reinforced member containing carbon fiber and thermoplastic resin. Background technique [0002] In recent years, so-called fiber-reinforced composite materials comprising a matrix resin and reinforcing fibers such as carbon fibers have come into focus in the machine field. The joining of such fibre-reinforced composite materials required for the production of components and structures is usually carried out by means of methods using closed sections provided for increased stiffness. Fiber-reinforced composite materials containing a thermoplastic resin as a matrix are joined by mechanical means using bolts and nuts, rivets, or the like, or by using adhesives. However, mechanical joints using bolts, nuts, etc. generally result in an i...
