Thedynamicviscoelasticpropertiesofbambooweretestedbydynamicmechanicsanalyzer(DMA),andthemeasurementsweredoneinthetemperaturerangeof40℃to300℃atfrequenciesof3Hz.Theresultsshowedthatwiththeincreaseofirradiationdose,thedecreaseofstoragemoduluswithincreasingtemperaturebecamemoredramatically.Thedecreaseextentofstoragemoduluswasthelowestfornon-irradiatedbamboo.Twomechanicalrelaxationprocesseswereobservedforallkindsofirradiatedbamboo.Thearelaxationprocessinlowertemperaturerangewasduetoglasstransitionofhemicelluloseandlogin,whiletheβrelaxationprocessoccurredinhighertemperaturerangewasbasedonglasstransitionofcellulose.Thelosspeakstrengthofαrelaxationprocesswentupastheirradiationdoseincrease,whilethelosspeakstrengthofβrelaxationprocessbecameupfirstandthendown,whichwascausedbythechemicalreactionofthechiefcompositionofbamboo.
