ABSTRACT:
The invention relates to a structure of open porosity in the form of a flat or curved panel made up of superposed layers of fibres with the orientation of the fibres varying from one layer to the next. The fibres are boron filaments held parallel in each layer by criss-crossing of filaments with another type. The boron filaments are bonded together at their crossing points to join superposed layers.
The invention also provides a method of making such porous structure.
