Abstract:

Toughness is one of the most critical parameters for aviation materials. Its maximization requires reaching high values of strain, Young s modulus, and ultimate strength, simultaneously, which makes the design and manufacturing of high-toughness materials quite challenging. Review of the current achievements and failures in this field give strongest possible indications that high performance materials with record toughness will require multiscale control of the structure of composites. This puts strict requirements on the composite processing technologies, but also opens the opportunities for the development of new class of practically and fundamentally important materials. In this proposal, we are taking advantage of the unique toolset provided by LBL deposition and dramatically increase toughness of composites working at the molecular, micro- and macro-scale levels of organization.
