SURFACE TREATMENT OF CARBON FIBER STRUCTURE

摘要

PURPOSE:To obtain a carbon fiber composite material having excellent mechanical strength by stably and safely performing the plasma surface modification of a carbon fiber having nap by applying low temp. plasma treatment to a carbon fiber structure in an atmosphere where charged particles such as electrons or ions are absent. CONSTITUTION:A carbon fiber structure is subjected to low temp. plasma treatment in an atmosphere where charged particles such as electrons or ions are absent. This atmosphere where charged particles such as electrons or ions are absent is set as the region on the side of the earth electrode 2 of the earthed conductive mesh 3 arranged between a discharge electrode 1 and the earth electrode 2.
