Method of detecting the oxidation of carbonaceous fibres or fibre bundles in composite materials

Detecting the oxidation of carbon-containing fibers or fiber bundles in composite materials comprises inducing a fluidized stream in the composite material, in which the fibers or fiber bundles are in the form of electrically conducting short fibers and are electrically insulated from each other by...

More Information
Summary:Detecting the oxidation of carbon-containing fibers or fiber bundles in composite materials comprises inducing a fluidized stream in the composite material, in which the fibers or fiber bundles are in the form of electrically conducting short fibers and are electrically insulated from each other by a non-conducting or semiconducting matrix, to produce a different output signal for oxidized fibers compared with non-oxidized fibers.
