RESEARCH ON THE IMPACT OF MARINE ENVIRONMENT ON THE SOUND TRANSMISSION PERFORMANCE OF THE POLYMER MATERIAL

Abstract

Abstract: The article describes the experiment of sound transmission property of CFRP, GFRP and polyurethane panels, the result shows that the adhered microorganism affects the sound transmission property a lot, the painted one is better than the unpainted one. The transmission coefficient decrease caused by marine ageing is less than 5.2%. GFRP panels show better sound transmission performance.

Key words: CFRP, GFRP, polyurethane, sound transmission, marine environment
