NEW ENERGY THERMAL MANAGEMENT COMPOSITE MATERIAL AGING LIFE TEST METHOD AND ALGORITHM, AND USE

Disclosed in the present invention are a test method and algorithm for an aging life of a composite, and a use thereof. The test method and algorithm includes: respectively placing specimens in four temperature environments to undergo damp and hot, high and low temperature impact and high and low temperature alternating cycle for a specified time; testing the physical, chemical and electrical properties of the specimens by using laminated combined test pieces; fitting parameters in a micro-gasification expansion oscillation equation; fitting constants in a kinetic correlation equation (2) of the parameters; calculating new values of the parameters in any temperature environment by using the constant equation (2); and substituting the new values of the parameters back into the equation (1), so as to evaluate or predict the physical, chemical and electrical properties of the specimens at any time. The highest aging test temperature can reach 298°C, not only the limitations of the GB/T 20028, ASTM G 166, ASTM G 169, ISO 2578 and UL 746B standards are broken through, but a linear correlation coefficient R2 is also two "9" accuracy levels higher, so that the prediction is more accurate.
