Title:
POLYMERIC MATERIAL REMAINING LIFE ASSESSMENT METHOD AND REMAINING LIFE ASSESSMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/199601
Kind Code:
A1
Abstract:
The present invention comprises a step for creating a degradation prediction model in which FT-IR spectra and mechanical properties of polymeric materials are correlated, and a step for acquiring the FT-IR spectrum and the mechanical properties of a polymeric material for actual use. The degradation prediction model is obtained by finding a correlation with the mechanical properties of the polymeric material for actual use from a weighted regression analysis using the intensities or areas of a plurality of peaks in an FT-IR spectrum which change due to degradation of a polymeric material and do not affect one another. In this way, a polymeric material remaining life assessment method and remaining life assessment device are provided which are capable of assessing the remaining life of a polymeric material more accurately than was conventionally possible.
