Composites Breakout Report-Out Workshop on Instrumentation, Metrology, and Standards for Nanomanufacturing, 10/17-19/06 Scientific and Technological Barriers Modeling Modeling  Modeling does not yet allow one to predict material properties and product performance based on inputs of raw materials, and processing.  Metrology to support such modeling often does not exist  Does not yet provide smooth continuum in scale.  Not sensitive to end need (performance) in complex systems  We often do not know what it is we need to model  Interdependency issues Metrology Metrology  Needs are approaching and going beyond the theoretical limits of current techniques; we lack basic understanding of nanocharcterization.

A defect in a nanotube?  Metrology needed to enable the needs of product manufacturing (cheap, fast, easy, operator independent)  Insufficient interoperability and standardization  Interdependency issues Limited Access to existing State of the art, especially for small businesses Limited Access to existing State of the art, especially for small businesses Insufficiently educated workforce Insufficiently educated workforce EHS is empirical and therefore lags discovery EHS is empirical and therefore lags discovery  Toxicity, exposure routes,  Effectiveness of PPE and engineering controls all experimentally determined
