A composite assembly with a laminate of fibre plies impregnated with a laminate matrix material is disclosed having pad of fibre plies impregnated with a pad matrix material, and a part with a body with protrusions which extend from the body and penetrate at least some of the fibre plies of the pad. The pad is bonded to the laminate by a stepped lap joint or a scarf joint. The assembly is manufactured by pressing the protrusions into the pad, and after the protrusions have been pressed into the pad, curing a pad matrix material impregnating the pad, and bonding the pad to the laminate.

The purpose of the present invention is to provide a thermal conductor achieving both excellent light weight and excellent rigidity and also having excellent heat dissipation property. In order to achieve the above object, the thermal conductor according to the present invention has the following configuration. That is, a thermal conductor in which a sheet-shaped thermal conductive material (II) having an in-plane thermal conductivity of 300 W/m.Math.K or more is contained in a porous structure (I) configured of reinforcing fibers and a resin.

A tube arrangement includes a composite tube defining a centerline axis, wherein the composite tube comprises a proximal surface and a distal surface, and an end fitting comprising a first end disposed within the composite tube and a second end extending from the composite tube, wherein an outer surface of the end fitting defines a flared portion defining a terminus of the first end, a lobe portion disposed axially from the flared portion, and a terminating portion disposed axially from the lobe portion, the proximal surface conforms to a geometry of the outer surface of the end fitting, the lobe portion and the flared portion mechanically lock the end fitting to the composite tube to mitigate movement of the end fitting relative to the composite tube.

The tube body intermediate includes: a carbon fiber disposed with respect to an outer circumferential surface of a mandrel such that the carbon fiber extends in an axial direction of the mandrel in a manner of being wound by less than one turn; and a first fixing member wound with respect to an outer circumferential surface of the mandrel such that the first fixing member extends in the axial direction of the mandrel in a manner of being wound over the carbon fiber by one or more turns in a circumferential direction.

A tube body production method includes: a disposing step of disposing carbon fibers with respect to an outer circumferential surface of a mandrel so that the carbon fibers extend in the axial direction of the mandrel; and a molding step of impregnating the fiber body with a resin on the outer circumferential surface of the mandrel and then heating the resin to mold the resin, wherein the disposing step and the molding step are performed in a state where the axial direction of the mandrel coincides with an up-down direction.

A method and an apparatus for manufacturing pre-preg are described. In this method, a fiber bundle of a fiber bundle roll is transferred to a wiping wheel and is flattened by several rollers. These rollers are arranged in sequence between the fiber bundle roll and the wiping wheel and are separated from each other. The fiber bundle is transferred by using the wiping wheel to impregnate the fiber bundle with a resin on a wheel surface of the wiping wheel. A tension of the fiber bundle on the rollers and the wiping wheel is controlled by using a tension controller during the transfer of the fiber bundle by the roller and the wiping wheel. The fiber bundle impregnated with the resin is wound by using a winding roller.
