摘要：

The　strain　of　the　T300/AG80　carbon　fibre　composite　laminated　plate　is　tested　when　it　is　irradiated　by　the　50W/cm2　laser　beam.　Strain　in　three　directions　of　0°,　45°　and　90°of　the　specimen　under　laser　beam　with　various　radii　is　recorded　by　the　dynamic　strain　testing　apparatus.　After　eliminating　the　influence　of　the　temperature,　the　data　shows　that　the　strain　of　the　tested　point　decreases　with　increase　of　its　distance　to　the　centre　of　laser　beam.　After　the　laminated　plate　is　irradiated　for　5　seconds,　in　the　direction　of　90°　the　maximum　relative　error　caused　by　the　temperature　in　the　experiment　is　16.9%,　and　in　concentric　circle　the　maximum　relative　error　18.4%　of　the　strain　gauges　is　in　the　direction　of　90°,　which　verifies　the　accuracy　of　the　model.　©　2011　IEEE.
