Abstract

A joined member assembly method includes: a step in which a substrate is inserted in a gap between a superposed first component and a second component, said substrate being configured from a multilayer fabric that is capable of expanding as a result of heating and that is flexible after expansion and a reinforcing material woven into the multilayer fabric; a step in which the substrate is heated and made to expand in the thickness direction; a step in which the gap is filled with a resin and the substrate is impregnated with the resin; and a step in which the resin is cured. A step in which a seam is created by machining in accordance with a measured gap shape is omitted.

First claim

The invention claimed is:

1. A joined member assembly method comprising:
inserting a base material comprising a multilayer structure fabric that is expandable by heating and is flexible after expansion and a reinforcing material woven into the multilayer structure fabric, into a gap between a plurality of overlapped members;
heating the base material so as to cause the base material to expand in a thickness direction;
filling the gap with a resin so as to cause the base material to be impregnated with the resin; and
curing the resin, and
wherein the multilayer structure fabric has a fabric layer in which at least two kinds of yarns which are different in thermal shrinkage so as to expand in the thickness direction by being heated are arranged,
wherein, in the heating of the base material so as to cause the base material to expand in the thickness direction, a yarn having relatively high thermal shrinkage shrinks by the heating so as to cause the fabric layer to expand in the thickness direction, and
the heating of the base material precedes the filling of the gap with the resin.

2. The joined member assembly method according to claim 1 ,
wherein the base material is heated so as to expand in the thickness direction, the expanded base material is inserted into the gap, the base material is thereafter impregnated with the resin, and the resin is thereafter cured.
