Abstract

transdutor acústico com um reforço traseiro contendo fibras unidirecionais e métodos de fabricação e uso do mesmo a descrição , em um aspecto, provê um aparelho que inclui um transdutor acústico e um reforço traseiro em contato com um lado do transdutor. o reforço traseiro inclui fibras substancialmente unidirecionais em uma matriz de um material que tem alta atenuação acústica para ondas de cisalhamento . as fibras contatam o lado do transdutor em um ângulo configurado para converter substancialmente todas, as ondas longitudinais que entram o reforço traseiro para o transdutor em ondas de cisalhamento, cujas ondas de cisalhamento são então atenuadas pela matriz do material do reforço traseiro.
