Abstract

A composite material includes laminated composite material sheets having conductivity, partitioning members provided between end parts of sets of the composite material sheets to mutually separate the sets of the composite material sheets, and metal sheets respectively provided in the separated end parts of the composite material sheets so as to be respectively pinched between the composite material sheets.

First claim

The invention claimed is:

1. A composite material, comprising:
laminated composite material sheets having conductivity, the laminated composite material sheets including at least a first sheet, a second sheet laminated on the first sheet, and a third sheet laminated on the second sheet, the first to third sheets having end parts;
partitioning members, folded in half, including at least a first member and a second member,
the first member being provided between the first sheet and the second sheet and extending in a longitudinal direction of the composite material sheets from the end parts of the first and second sheets for a determined length to separate the first and second sheets from each other,
the second member being provided between the second sheet and the third sheet and extending in the longitudinal direction from the end parts of the second and third sheets for the determined length to separate the second and third sheets from each other; and

metal sheets respectively provided to the end parts of the first to third sheets, each end part having a shape to pinch corresponding one of the metal sheets.

2. A composite material, comprising:
laminated composite material sheets having conductivity, the laminated composite material sheets including at least a first sheet, a second sheet laminated on the first sheet, and a third sheet laminated on the second sheet, the first to third sheets each having a surface and an end part;
partitioning members, folded in half, including at least a first member and a second member,
the first member being provided between the first sheet and the second sheet and extending in a longitudinal direction of the composite material sheets from the end parts of the first and second sheets for a determined length to separate the first and second sheets from each other,
the second member being provided between the second sheet and the third sheet and extending in the longitudinal direction from the end parts of the second and third sheets for the determined length to separate the second and third sheets from each other; and

metal sheets respectively joined to the surfaces of the first to third sheets at the end parts thereof.

3. A composite material, comprising:
laminated composite material sheets having conductivity, the laminated composite material sheets including at least a first sheet, a second sheet laminated on the first sheet, and a third sheet laminated on the second sheet, the first to third sheets having first end parts and second end parts;
partitioning members including at least a first member and a second member,
the first member being provided between the first sheet and the second sheet and extending in a longitudinal direction of the composite material sheets from the first end parts of the first and second sheets for a determined length to separate the first and second sheets from each other,
the second member being provided between the second sheet and the third sheet and extending in the longitudinal direction from the first end parts of the second and third sheets for the determined length to separate the second and third sheets from each other; and

metal sheets respectively provided to the first end parts of the first to third sheets, each first end part having a shape to pinch corresponding one of the metal sheets,
wherein the first to third sheets each have a strip shape with a different length from each other, and the first to third sheets are laminated so that second end parts where the partitioning members are not provided are aligned.

4. A composite material, comprising:
laminated composite material sheets having conductivity, the laminated composite material sheets including at least a first sheet, a second sheet laminated on the first sheet, and a third sheet laminated on the second sheet, the first to third sheets each having a surface, a first end part, and a second end part;
partitioning members including at least a first member and a second member,
the first member being provided between the first sheet and the second sheet and extending in a longitudinal direction of the composite material sheets from the first end parts of the first and second sheets for a determined length to separate the first and second sheets from each other,
the second member being provided between the second sheet and the third sheet and extending in the longitudinal direction from the first end parts of the second and third sheets for the determined length to separate the second and third sheets from each other; and

metal sheets respectively joined to the surfaces of the first to third sheets at the end parts thereof,
wherein the first to third sheets each have a strip shape with a different length from each other, and the first to third sheets are laminated so that second end parts where the partitioning members are not provided are aligned.

5. The composite material according to claim 3 , further comprising a common lead coupling part to which a common lead that applies current to the composite material is electrically coupled, the common lead coupling part being provided in a part of the composite material where the composite material sheets are not separated.

6. The composite material according to claim 4 , further comprising a common lead coupling part to which a common lead that applies current to the composite material is electrically coupled, the common lead coupling part being provided in a part of the composite material where the composite material sheets are not separated.

7. A composite material, comprising:
a first composite material sheets including at least a first sheet and a second sheet having conductivity, the second sheet being laminated on the first sheet;
a second composite material sheet being disposed to partially overlap with the first composite material sheet, the second composite material sheet including at least a third sheet and a fourth sheet having conductivity and end parts, the fourth sheet being laminated on the third sheet, the end parts being on a side opposite to a side where the second composite material sheet overlaps with the first composite material sheet;
a conductor penetrating both the first and second composite material sheets;
a partitioning member folded in half and provided between the third sheet and the fourth sheet of the second composite material sheet, the partitioning member extending in a longitudinal direction of the second composite material sheet from the end parts of the first and second sheets for a determined length to separate the third and fourth sheets from each other; and
metal sheets provided to the end parts of the third and fourth sheets, each end part having a shape to pinch corresponding one of the metal sheets.

8. A composite material, comprising:
a first composite material sheets including at least a first sheet and a second sheet having conductivity, the second sheet being laminated on the first sheet;
a second composite material sheet being disposed to partially overlap with the first composite material sheet, the second composite material sheet including at least a third sheet and a fourth sheet each having conductivity, a surface, and an end part, the fourth sheet being laminated on the third sheet, the end parts being on a side opposite to a side where the second composite material sheet overlaps with the first composite material sheet;
a conductor penetrating the first and second composite material sheets;
a partitioning member folded in half and provided between the third sheet and the fourth sheet of the second composite material sheet, the partitioning member extending in a longitudinal direction of the second composite material sheet from the end parts of the first and second sheets for a determined length to
