acoustically active material |
| abstract |
The present invention provides a polymer matrix composite material comprising a porous polymer network structure; and a plurality of acoustically active particles distributed within the polymer network structure. The weight fraction of acoustically active particles is between 0.80 and 0.99 based on the total weight of the polymer matrix composite. The polymer matrix composite has an airflow resistance of less than 100 sec/50 mL/500 μm. |
