Organizations heavily involved in such research are ASCE-HITEC, NIST,
USACERL, USAE Waterways, FHWA, State DOTS, Research Council of Canada,

Aren't you glad you asked !!

Having more than 15 years progressive engineering and technical
knowledge of high performance advanced composite materials for
structural use (teflon coated fiberglass,silicone coated fiberglass,
hypalon coated kevlar, CFRP, GFRP,et al)  , I am now offering - at my
wife and kids urging - structural consulting services in this field to
whoever requires unabashed, unbiased, direct, timely and clear 
assistance, guidance, presentations, professional opinions, reviews
and  specifications related to the design, selection and installation
of such advanced composite systems.
