PROBLEM TO BE SOLVED: To provide a method and apparatus for producing a composite filler having a variable cross section along its length, that are reliable and repeatable, and which reduce labor costs by automating the fabrication process, and to provide a method and apparatus as described above which result in a filler having improved stiffness, toughness and/or resistance to cracking.SOLUTION: The apparatus for producing a composite filler includes at least one die and a device for moving a stack of reinforced ply strips through the die. The die has peripheral die face adapted for forming the ply strip stack into a desired cross sectional shape. The cross section of the die face may vary around the periphery of the die.

PROBLEM TO BE SOLVED: To provide a method for producing a mold for molding a composite material using a prepreg material.SOLUTION: First, a material 200 of a mold having a long two-dimensional shape and in a smei-cured state is produced by continuous pultrusion molding of a prepreg sheet. Next, the semi-cured base material 200 is mounted on a plurality of templates 131, 132, 133, 134, 135 vertically provided on a base plate 120 of a molding apparatus 100 to be plastically deformed into a three dimensional shape. The entire molding apparatus 100 is heated and pressurized to produce a completely cured mold for molding.

PROBLEM TO BE SOLVED: To provide a composite structural member suitable for a secondary work and its production method. SOLUTION: The composite structural member 9 is provided with a solid core 10 formed of polymer, a secondary layer 12 covering the solid core 10, and the outermost coating material 13 which is formed of polymer and is arranged on the concentric circle. The solid core 10 is formed of a thermosetting material hardened in a B-state, and the secondary layer 12 and the outermost coating material 13 are respectively formed of a thermoplastic material. In this case, the material constituting layers 10, 12, 13 is selected so that the hardening temperature of the solid core 10 and the melting point of the outermost coating material 13 become higher than the melting point of the secondary layer 12.
