Regular structures with little or no branching allow the polymer chains to fit close together, forming a crystalline structure crystalline structures are generally stronger, more brittle, of higher density, more resistant to chemical penetration and degradation, less soluble, and have higher melting points. Semi-crystalline polymers high temperature materials are divided into two main categories—semi-crystalline and amorphous—based on their difference in molecular structure semi-crystalline materials have a highly ordered molecular structure with sharp melt points. Engages in research, development, and flight application of advanced materials, structures, and mechanisms for aerospace systems, with activities ranging from materials research at nanoscale to design and testing of structures and mechanical systems for aeronautics and space flight programs.
