The construction of a Nomex top should be called as “Double top” and consists in a “sandwich” made by two outer sheets of wood, separated by Nomex. The result is like the structure we would obtain if we cut a thin sheet of a honeycomb. The walls of the cells are about 0,2 mm thick, and the size of the cells is of approximately 3,5 mm between opposed vertices.
This material is extremely light and is composed by Kevlar fibre. It was first developed as a thermal insulating in the manufacturing of clothing and footwear for astronauts, but now is used in the construction of boards and light structures in aeronautic industry, classic guitars and other applications.
