Abstract
A method of joining a first bulk composite core and a second bulk composite core by applying an adhesive to a surface network of the first bulk composite core; inserting a plurality of mandrels into a plurality of cell members of the first bulk composite core and a plurality of cell members of the second composite core, thereby aligning the cell members of the first bulk composite core to the cell members of the second bulk composite core; pressing the respective surface networks of the first bulk composite core and the second bulk composite core together with the adhesive located therebetween; and curing the adhesive.
Claims17
A method of joining a first bulk composite core and a second bulk composite core, the method comprising the steps of:
- applying an adhesive to a first surface network of the first bulk composite core, the first surface network being an exposed surface at a first termination end of a plurality of cell members of the first bulk composite core;
- inserting a plurality of mandrels into the plurality of cell members of the first bulk composite core and a plurality of cell members of the second composite core, thereby aligning the cell members of the first bulk composite core to the cell members of the second bulk composite core, the second bulk composite core having a second surface network that is an exposed surface at a first termination end of a plurality of cell members of the second bulk composite core;
- pressing together the first surface network of the first bulk composite core and the second surface network the second bulk composite core with the adhesive located therebetween;
- and
- curing the adhesive.
A method of joining a first bulk composite core and a second bulk composite core, the method comprising the steps of:
- applying an adhesive at a midportion of each of a plurality of mandrels, the midportion being between a first end and a second end of each mandrel;
- inserting the plurality of mandrels into a plurality of cell members of the first bulk composite core and a plurality of cell members of the second composite core, thereby aligning the cell members of the first bulk composite core to the cell members of the second bulk composite core;
- pressing the respective surface networks of the first bulk composite core and the second bulk composite core together;
- and
- curing the adhesive.
A method processing a first bulk composite core and a second bulk composite core, the method comprising the steps of:
- applying an adhesive to a first surface network of the first bulk composite core, the first surface network being an exposed surface at a first termination end of a plurality of cell members of the first bulk composite core;
- inserting a plurality of mandrels into the plurality of cell members of the first bulk composite core and a plurality of cell members of the second bulk composite core, thereby aligning the cell members of the first bulk composite core to the cell members of the second bulk composite core, the second bulk composite core having a second surface network that is an exposed surface at a first termination end of a plurality of cell members of the second bulk composite core;
- pressing together the first surface network of the first bulk composite core and the second surface network of the second bulk composite core together with the adhesive located therebetween;
- curing the adhesive;
- removing the plurality of mandrels;
- and
- cutting through at least one of the first bulk composite core and the second bulk composite core so as to create a wafer therefrom.
