Abstract:An equation on atmospheric aging age with high confidence and reliability have been founded by studying and analysing a lot of atmospheric aging data about polymer matrix composites. Then the atmospheric aging age and aging residual strength with high confidence and reliability, which is badly in need of providing in engineering design can be calculated. Meanwhile a litter sample method that can define parameters in this aging equation has been advanced. This method can save above 50 percent specimen comparing with the traditional testing method in group under the same precision and it can improve precision on estimating greatly with the same amount of specimens. Finally a verifying example has been given.
Keywords:composite  aging age  reliability
