Abstract

A panel of composite material including two outside skin parts, a plurality of stringers, connecting members for connecting the plurality of stringers, and a reinforcing member connecting the two outside skin parts with each other. Each of the two outside skin parts is formed into one body. A portion protruding upward from the plurality of stringers is provided on the connecting members, and is connected to the reinforcing member by a fastener.

Claims

1. A panel of composite material comprising:

two outside-skin parts, each including an outside skin, a plurality of stringers, connecting members for connecting the plurality of stringers, and

a reinforcing member connecting the two outside-skin parts with each other;

wherein

each of the two outside-skin parts is formed into one body,

at least one of the connecting members has a portion protruding upward from the plurality of stringers,

the portion is connected to the reinforcing member via a fastener.

2. An aircraft containing the panel of claim 1.

3. A wing of composite material comprising:

two outside-skin parts, each including an outside skin, a plurality of stringers, connecting members for connecting the plurality of stringers, and

a reinforcing member connecting the two outside-skin parts with each other;

wherein each of the two outside-skin parts is formed into the shape of a wing,

at least one of the connecting members has a portion protruding upward from the plurality of stringers, and

said portion is connected to the reinforcing member via a fastener.
