University of Houston Builds Full-Scale Highway Sign Structure from Retired GE37 Wind Blade Segments
Dr. Nagesh Ramaswamy and a University of Houston research team designed, validated, and constructed a full-scale overhead highway sign structure using retired GE37 wind turbine blade sections supplied by Carbon Rivers as primary columns and horizontal members.
Manufacturing & Process Note: Repurposing retired blade spar caps with tensile strengths near 90 ksi shifts the cost burden from raw material procurement to inspection and connection engineering; plant managers should budget for non-destructive testing of legacy laminates and for specialized load-transfer hardware before committing to structural reuse programs.
