US 2017/0291387 A1 · COMPOSITE STRUCTURE AND MANUFACTURING METHOD THEREOF

Abstract

A composite structure having a laminated structure made of fiber reinforced plastic and metallic material comprises a base member(s) made of metallic material; and a reinforcement member(s) made of fiber reinforced plastic, the reinforcement member(s) comprising: a first reinforcement part(s) made of fiber reinforced plastic including reinforcement fibers which are aligned in a uni-direction, and a second reinforcement part(s) made of fiber reinforced plastic including at least reinforcement fibers which are aligned in a crossing direction relative to the uni-direction in which the reinforcement fibers of the first reinforcement part(s) are aligned, and interposed between the base member(s) and the first reinforcement part(s), the reinforcement member(s) further comprising a thermosetting resin included in a bonding site with the base member(s).

Dependent claims

A composite structure having a laminated structure made of fiber reinforced plastic and metallic material, comprising:

a base member(s) made of metallic material, having a sheet type;
and a reinforcement member(s) made of fiber reinforced plastic, wherein
the reinforcement member(s) is bonded with the base member(s) so as to comply with an inner surface profile of the base member(s), and comprises:
a first reinforcement part(s) made of fiber reinforced plastic including reinforcement fibers which are aligned in a uni-direction, and
a second reinforcement part(s) made of fiber reinforced plastic including at least reinforcement fibers which are aligned in a crossing direction relative to the uni-direction in which the reinforcement fibers of the first reinforcement part(s) are aligned, and interposed between the base member(s) and the first reinforcement part(s),
the reinforcement member(s) comprising a thermosetting resin included in a bonding site with the base member(s).

A manufacturing method of a composite structure having a laminated structure made of fiber reinforced plastic and metallic material, comprising:

laminating a base member(s) made of metallic material, having a sheet type;
a first reinforcement part precursor(s) formed of a prepreg(s) which is made of a fiber reinforced plastic including reinforcement fibers which are aligned in a uni-direction;
and a second reinforcement part precursor(s) formed of a prepreg(s) which is made of fiber reinforced plastic including at least reinforcement fiber which are aligned in a crossing direction relative to the uni-direction in which the reinforcement fibers of the first reinforcement part precursor(s) are aligned, each other, by interposing the second reinforcement part precursor(s) between the base member(s) and the first reinforcement part precursor(s), wherein the first and second reinforcement part precursors are complied with an inner surface profile of the base member in order to bond the precursors onto the base member;
and
heating the laminated structure produced by the laminating, having a base member(s), the first reinforcement part precursor(s) and the second reinforcement part precursor(s).
