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

Disclosed is a curable epoxy resin composition having excellent flexibility and toughness, comprising (a) an epoxy resin, (b) a glycol type di(meth)acrylate, (c) a nitrogen containing heterocyclic compound, and (d) a polyamine having at least two amino groups with an active hydrogen. The resin composition is very suitable for a vibration damping laminate.
