Abstract
A composite material having a reduced weight, while its strength is improved to provide a higher damage suppressing effect. Resin layers (2, 2) are laminated on each surface of the metal layer (1) formed of a shape-memory alloy (SMA) to which a strain was imparted. And a fiber-reinforced resin layer part (3) including a plurality of fiber-reinforced resin layers (31 to 34) is laminated on each resin layer (2, 2), respectively.
Claims5
A composite material comprising:
- a fiber-reinforced resin layer part including a plurality of fiber-reinforced resin layers in different fiber arrangement directions, the layers being laminated with each other;
- a metal layer made of a structural metal material, which is disposed between the fiber-reinforced resin layer parts;
- and
- a resin layer which attaches the metal layer and the fiber-reinforced resin layer part to each other.

A method of manufacturing a composite material comprising the steps of:
- imparting a strain to a shape-memory alloy foil;
- laminating a resin layer on each surface of the shape-memory alloy foil;
- laminating a plurality of uncured fiber-reinforced resin layers on the resin layer;
- securing both ends of the shape-memory alloy foil to prevent a length of the foil from being changed;
- and
- heating the shape-memory alloy foil to cure the resin layer and the fiber-reinforced resin layers.
