A novel acoustic foam was developed by Polytechnique Montreal in response to the needs of the aviationx000D
industry. The thermoset polymeric open-cell foam shows excellent acoustic absorption coefficient in broadx000D
frequency range, and particularly at low frequencies. Further, is light and mechanically strong. The foamsx000D
mechanical properties are attractive for applications in aircraft engines, flooring systems and fuselage. Thex000D
fabrication process is simple and reliable. Acoustic specialists in the aeronautics and the building constructionx000D
fields have recognized the potential of the proposed product and a provisional patent has been filed. Thex000D
companies approached are welcoming this unexampled multifunctional technology with high potential forx000D
commercialization, and are calling for further testing and improvements.x000D
The purpose of this project is to respond to industry requirements prior to industrialization by validating thex000D
technology in relevant environment. The objective is to prove that the manufacturing process parameters arex000D
fully controlled, and that these thermoset foams respect acoustic, physical and mechanical specifications fromx000D
industry. The project will show the benefits of making these low-cost acoustic foams with flight certifiedx000D
thermosetting resins. The fabrication process will be optimized. Large samples will be manufactured. Differentx000D
resin systems and foam structures will be tested. Acoustic performance, mechanical properties andx000D
airworthiness will be assessed experimentally. Effectiveness of acoustic prediction tools will be verified.x000D
Integration in representative aerospace sandwich structure will be tested.x000D
This new technology will contribute to the economic health and growth of the 211 000 jobs and 28 G$x000D
Canadian aerospace industry. It is providing a means of limiting the "adverse community reaction related to thex000D
operation and expansion of airports" deplored by the International Civil Aviation Organisation. Mitigation ofx000D
aircraft noise is among manufacturers and airport managers' top priorities and key environmental goals.
