Abstract:

In order to give full play to renewability and biodegradability of nature bamboo fiber and reduce the environmental load of sound insulation composite material and further improve sound insulation performance of natural bamboo fiber/polyurethane composite material, a series of sound insulation composite materials were prepared in different ways using the natural environment-friendly and renewable bamboo fiber as the reinforcing material and polyurethane as base material. The influence of bamboo fiber packing modes, NaoH solution surface treatment and natural bamboo fiber content on the sound insulation composite materials was studied. The results showed that sound insulation performance of composite material with straight fibers packing is the best. Sound insulation performance is improved when fibers were treated by NaoH solution. With the natural bamboo fiber content increases, the sound insulation performance of composites increases.
