METHOD FOR MANUFACTURING A FILTERING PART IN THE FORM OF ACTIVE CARBON FIBERS AND PROTECTIVE COATING PART AS OBTAINED BY THE METHOD

摘要

The method comprises the steps which consist of producing a workpiece preform in a coherent texture of carbon precursor fibers, implementing a confection process such as knitting, two-dimensional texture sewing or braiding; and performing a carbonization and activation treatment to directly obtain the desired shaped part made of activated carbon fibers; the preform being dimensioned to take account of shrinkage during the carbonization and activation treatment. The process can be used in particular to produce pieces of protective clothing against attacks such as nuclear, bacteriological or chemical.
