RAMAN spectroscopy for identification of aerospace composites (RASAC)
Start date: Nov 1, 2012, End date: Jan 31, 2014 PROJECT  FINISHED 

"In the coming decades throusands of aircraft are due to be retired and dismantled. Other than components to be re-used, substantial parts of aircraft are stripped and shredded. Whereas today's technologies such as XRF work well in many respects, XRF is unable to properly identify aircraft composites, penetrate coatings and XRF is also costly.This proposal will modify and refine RAMAN spectroscopy devices to demonstrate their capability to robustly identify aerospace composites, also when subject to ageing and coating.RAMAN is a well-established spectroscopy technique outside the aerospace domain. It works by shining a laser beam on a sample, and identifying the molecular vibration response.TNO has access to a handful of different RAMAN devices to perform the feasibility study. To enforce industrial, economic and operational realism, we are bringing companies AELS and Avantes as subcontractors. Both are very active and well-established in European recycling networks. TNO also brings a relevant industrial network to support further industrial development of a portable RAMAN device."
