非连续湿热作用对T700/TR1219B复合材料宏细观性能的影响
Effect of Discontinuous Hygrothermal on Macroscopic and Microscopic Properties of T700/TR1219B Composites
摘要
Abstract
In order to study the effect of discontinuous hygrothermal on properties of T700/TR1219B composite,the specimens were treated with discontinuous hygrothermal treatment.The tensile test was carried out and SEM was used to observe the lateral morphology.The nano-indentation test was conducted by peak force quantitative nano-mechanics technique (PF-QNM) of atomic force microscope (AFM) to analysis the discontinuous hygrothermal effect on properties of resin.The results show that when the rate of moisture absorption varies from 0％ to 1.2％,the first time and the second time moisture absorption of T700/TR1219B composite follow the Fick law.Tensile strength and elastic modulus of specimens and hardness and elastic modulus of resin increase firstly and then decrease.关键词
