  • Methods and systems for designing a composite structure
    Patent number: 10983078
    Abstract: A computer-implemented method of determining moisture content of a composite structure is provided. The method includes performing a thermal analysis calculation on the composite structure to determine a temporal surface temperature profile of the composite structure based on temporal environmental parameter profiles, wherein the surface temperature profile is determined independently of a moisture content of the composite structure. The method also includes performing a moisture content analysis calculation on the composite structure to determine a moisture content of the composite structure, wherein the moisture content analysis calculation is based on the determined temporal surface temperature profile and a thickness of the composite structure. The thermal analysis calculation is performed iteratively with a first time period and the moisture content analysis calculation is performed iteratively with a second time period that is longer than the first time period.
    Type: Grant

  • METHODS AND SYSTEMS FOR DETERMINING AN ALLOWABLE MOISTURE CONTENT IN A COMPOSITE STRUCTURE
    Publication number: 20160370309
    Abstract: A method of determining an allowable moisture content of a composite structure includes performing a thermal analysis on the composite structure to determine a surface temperature profile of the composite structure. The surface temperature profile is determined independently of a moisture content of the composite structure. The method also includes performing a moisture analysis on the composite structure to determine an allowable moisture content of the composite structure such that the moisture analysis is based on the determined surface temperature profile.
