摘要
对有机玻璃的断裂韧性因子K值从测试条件和工艺配方的角度进行了一定的阐述。讨论了影响K值稳定性和准确性的条件因素,对试验数据进行了分析处理,完善了有机玻璃K值的测试条件。
The fracture toughness factor K of PMMA was investigated from the aspects of formula and test conditions . Some elements which influence the stability and accuracy of the factor K were discussed . The experiment data were processed and the test conditions of the factor K for PMMA were completed.
