Abstract
PURPOSE: To obtain a member being strong and excellent in a noise-proof property, by a method wherein a subject member for absorbing car engine noise is produced such that a given percent of rubber powder is added to thermosetting resin.
CONSTITUTION: A strength member for a sound-absorbing damping material comprises components, such as unsaturated polyester resins 1 or the like in addition to rubber powder 3, and calcium carbonate 2 or the like is further added as required as a filler. The rubber powder 3 at 5W50wt% is contained in a composition. If the content is less than 5wt%, a sound-absorbing property is hardly improved. Meanwhile, if it exceeds 50wt%, it weakens a binding strength and is not suited as a reinforcement member.
