Abstract
Chemical modification of AMS 3277 sealants has reached a point that gains in service temperature are becoming more and more difficult to achieve while retaining important sealant properties. The proposed approach forms nanocomposite high temperature sealants from existing off-the-shelf PRC 2001 and PRC 1826 sealants, and surface modified Cloisite nanoparticles. A pre-bid experiment showed that the storage modulus PRC 2001 achieves at 320°F can be achieved in the nanocomposite at 405°F - an 85°F improvement without optimization. Using nanoparticle surface modification methods developed by our team the sealants will be optimized with a goal in Phase I of a 400°F service temperature without loss of sealant properties as defined by AMS 3277 and PRC 2001/1826 data sheets. Deliverables include a full suite of test data for each sealant with a 1 to 1 comparison against current PRC 2001/1826 properties, a Phase I specification, and sample material for independent testing. Blends of commercial sealants with 6-8 off-the-shelf nanoparticles will be made to identify those that demonstrate improving thermal stability. The best performing nanoparticles will be modified through surface and edge treatments to optimize sealant formulations for high service temperatures while retaining physical, thermal, rheological, and curing properties.
