The present invention has an object of providing a molded article of a composite structure obtained by bonding a polar thermoplastic resin, especially polyacetal, with another resin in a simple manner. According to the present invention, a molded article of a composite structure obtained by bonding a polar thermoplastic resin and a resin containing an aliphatic ester structure as a main component to each other in the state where at least a face at which both of the materials contact each other is in a melted state can be provided.

Composite molded article having two-layer structure

A SMC sheet includes: a sheet material body made of a resin compound containing uncured thermosetting resin; and a fiber sheet embedded as an intermediate layer in the sheet material body and impregnated with the thermosetting resin of the sheet material body. Short fiber is distributed on at least one side of the fiber sheet in the sheet material body.

SMC sheet and method for manufacturing the same

A composite resin molded product has a molded product body made of a resin and a fiber sheet material inserted on the surface of the molded product body. The fiber sheet material is formed of a knitted fabric, and the rear surface of the knitted fabric faces the molded product. The surfaces of fiber yarns of the knitted fabric are integrated with the molded product body by melting and solidifying.

Composite resin molded product and method for molding the same

A braided structure forming method suitable for forming a braided structure of a complicated structure capable of serving as the core of FRP and FRTP, in which a speed of pulling up or down a braided structure is varied in process with time to vary the structural density thereof.

Braided structure forming method

Multi-layer tubular braided structures are produced by apparatus including a plurality of generally concentric pairs of serpentine, intersecting bobbin carrier-guiding tracks. A bobbin carrier driving gear group is associated with each pair of tracks, adjacent gear groups meshing at a plurality of bobbin carrier crossover points. According to the method, multi-layer tubular braided structures are produced by circulating a first group of bobbin carriers exclusively along one track of a first pair of tracks, circulating a second group of bobbin carriers exclusively along one track of a second pair of tracks, and circulating at least one other group of bobbin carriers exclusively along at least portions of the other tracks of said pairs of tracks via the crossover points.

Apparatus for multiple layer tubular braiding

A braided structure forming device suitable for forming a braided structure of a complicated structure capable of serving as the core of FRP and FRTP, in which a speed of pulling up or down a braided structure is varied in process with time to vary the structural density thereof.

Braided structure forming apparatus

A braiding method comprising moving bobbin carriers along tracks connecting a plurality of braiding regions to braid cords or strands in a specific braiding region, in another braiding region or in all the braiding regions. The braid may be used as core structure for fiber-reinforced plastics.

Braid and braiding method

The apparatus comprises a tubular braid machine, a mandrel having branched portions, a holding body for the mandrel capable of effecting upward movement, downward movement, horizontal movement about a braiding point or rotation within a vertical surface, an annular guide detachably mounted at a braiding position to a mandrel main portion, an annular guide detachably mounted at a braiding position to a mandrel branch portion, and a closeable annular guide detachably mounted therebelow.

Braiding apparatus for a tubular braid structure

A braiding apparatus and method for moving bobbin carriers along tracks connecting a plurality of braiding regions to braid cords or strands in a specific braiding region, in another braiding region or in all the braiding regions. The braid may be used as core structure for fiber-reinforced plastics.

Method and apparatus for braiding in two braiding regions

The energy absorbing structure of the present invention comprises a cylindrical hollow body of a fiber reinforced thermoplastic resin wherein both the ends are open, the cylindrical hollow body being attached to the outer wall of a moving body or the outer wall of a stationary body with which the moving body comes in contact in such a manner that the opening of the hollow body faces the outer wall.
