Abstract
A method of manufacturing a honeycomb structure, the method comprising the steps of forming staggered cells through the entire thickness of a fiber fabric, causing loosely held pegs to penetrate into respective ones of the cells, each peg having a cross-section of size smaller than that of the corresponding cell and being made of a material that is suitable for expanding; expanding the pegs so that they fill the cells and exert pressure on the inside faces of the cells; and shrinking the pegs and then withdrawing them.
