| titleOfInvention | Composite material for acoustic dampener |
| abstract | FIELD: radio electronic equipment. SUBSTANCE: material may be used in design of equipment using surface acoustic waves. Composite material of acoustic dampener contains epoxy low- molecular resin, which molecular weight is not greater than 400. Hardener is designed as low-molecular aliphatic polyamide, which molecular weight is not greater than 1000. filler is designed as silicon dioxide powder. Maximum of granulometric distribution of silicon dioxide grains is within range of λ/4 and λ/2, where λ is wavelength of surface acoustic wave. Weight content of components in composite material is within range of 1.8-2.2 of epoxy low-molecular resin, 6.5-7.5 of low-molecular aliphatic polyamide, 1-1.5 of silicon dioxide. EFFECT: facilitated production of material, increased level of noise suppression. 1 tbl, 1 dwg |
