This limit depends on the sensitivity of each typeof composite to the misalignment defect.NOTE 1 This limit is to be defined between the testing establishment and the customer.NOTE 2 Monolithic ceramics are very sensitive to misalignment defects, while ceramic matrix composites (CMCs) ingeneral are moderately sensitive to them.【中国标准分类号】: Q32【国际标准分类号】: 81_060_30【页数】: 18P.;A4【正文语种】: 英语
