Raman spectroscopic characterization of laminated glass and transparent sheet plastics to amplify a history of early aviation ‘glass’

“…A full‐page advertisement extolling its light weight, hardness, impact strength, perfect transparency, weathering, and ease of forming appeared in the July 1937 issue of the New York based journal, Aero Digest , where it was placed prominently opposite the table of contents . Windows, gun‐turrets, observation blisters, and nose cones of PMMA soon proliferated and became popular symbols of World War II aeronautic technology . Rohm and Haas had operations in Germany and the United States, and their Plexiglas was used in both markets .…”

“…[35] Windows, gun-turrets, observation blisters, and nose cones of PMMA soon proliferated and became popular symbols of World War II aeronautic technology. [37,38] Rohm and Haas had operations in Germany and the United States, and their Plexiglas was used in both markets. [32] Raman analysis shows that PMMA was the plastic sheet of transparent canopies on two experimental 'Horten' German jet airplanes constructed during World War II; the Horten H III h and Horten H IX V3 each feature a PMMA canopy constructed in three parts (Fig.…”
