This thesis investigated the thermal and oxidative degradation of 5250-4 neat resin powder in argon, air, and oxygen environments. The powder was agedat 163, 177, and 190 ⁰C in all environments for at least 250 hours. Isothermal thermo-gravimetric analysis demonstrated that weight loss was negligible for agingin the argon environment, indicating weight loss isthe result of an oxidative process at these temperatures.The 5250-4 powder exhibited an initial period of weightgain before eventually losing weight inboth air and oxygen. The applicabilityof a closedloop oxidation scheme to 5250-4 gravimetric behavior was investigated. Kinetic parameters for the scheme were determined for the AirForce Research Laboratory's polymermatrix composite lifetime prediction modeling efforts.\u003c\/p\u003e","brand":"Biblioscholar","offers":[{"title":"Paperback","offer_id":47599028273303,"sku":"9781286866801","price":5106.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9781286866801.webp?v=1775002886","url":"https:\/\/atlanticbooks.com\/products\/high-temperature-degradation-of-5250-4-polymer-resin-9781286866801","provider":"Atlantic Books","version":"1.0","type":"link"}
