| titleOfInvention | Material for processing and molded member using the same |
| abstract | The present invention provides a material for processing and a molding member using the material for processing which can greatly improve vibration damping performance, sound insulation performance, and sound absorption performance, and can reduce the weight and mechanical strength of the product. According to the metal cover 1a, many through-holes 22 are formed in the thin-plate material 6 which comprises the processing material 24. As shown in FIG. Thereby, the processing material 24 forms the through-hole 22 in itself. When the work material 24 vibrates, friction between air and the end face 32 constituting the through hole 22 of the work material 24 when air passes through the through hole 22. Attenuation of energy occurs. For this reason, the energy of the sound wave which is the vibration of air is converted into heat energy, and the sound absorption performance is exhibited. The frequency band in which the sound absorption performance is exerted is determined on the basis of the length shape such as the equivalent hole diameter D1, the opening ratio, the plate thickness of the through hole 22, and the like. |
