The method comprises the steps consisting in making a preform of the piece to be manufactured out of a coherent fabric of carbon precursor fibers, by using a manufacturing process such as knitting, stitching the two-dimensional fabric, or braiding; and performing carbonization and activation treatment to obtain directly the desired shaped piece made of activated carbon fibers; the preform being dimensioned so as to take account of shrinkage during the carbonization and activation treatment. The method can be used in particular for making pieces of clothing to provide protection against attack such as nuclear, biological, or chemical attack. |
