摘要：

The　material　mass　ablative　law　of　the　carbon　fiber　epoxy　composite　irradiated　by　continuous　wave　Nd:YAG　laser　was　researched　by　experiment.　The　results　indicate　that　the　composite　ablative　mass　is　directly　proportional　to　the　laser　radiation　energy　when　the　laser　radiation　intensity　is　greater　than　10　kW/cm2;　with　the　same　laser　energy　radiation,　the　mass　ablative　rate　at　high　intensity　of　0.65　mm　laser　spot　radius　is　nearly　twice　that　at　low　intensity　of　5.5　mm　laser　radius;　combustion　phenomena　cause　the　mass　ablative　rate　to　fluctuate　when　the　irradiation　laser　power　is　near　the　composite　burning　threshold.
