Abstract

The invention discloses a method for predicting the service life of a composite member. The method is as follows: the failure time of the composite member in a natural weathering aging test, namely the service life of the composite member can be obtained by determining a correlation coefficient R between the natural weathering aging test and an artificial accelerated aging test, obtaining the failure time T3 of the composite member in the artificial accelerated aging test and calculating through a correlation formula. By using the method disclosed by the invention, the testing time can be shortened, and the testing cost can be saved. The method disclosed by the invention is applicable to the prediction of the service life of resin type composite members.

Description

technical field [0001] The invention relates to a life prediction method, in particular to a life prediction method of a composite material component. Background technique [0002] Composite materials, that is, resin-based composite materials, have been widely used in building materials, aerospace, aviation and other departments due to their advantages such as light weight, high strength, corrosion resistance, convenient processing and molding, and good designability. [0003] However, components made of composite materials, such as towers used in power facilities, generally have a service life of 10 years or more, and the natural climate of composite components is changing all the time, and are subject to many Due to the influence of human factors, the service life of composite components in the natural climate environment, that is, the natural failure time, cannot be known. However, a stable and enhanced natural climate environment can be artificially simulated, that is, ...
