複合膜の製造
粒子の総質量に対して8質量%〜10質量%を示す銀の層で被覆されたポリアミド11(ARKEMA社から供給されたRilsan(登録商標)PA11)の粒子をCVDによって得た。これらの複合粒子は、レーザ粒径分析で測定すると、直径D50が100μmであった。金属被覆物の厚さは約150nmであった。
(比較):複合膜の製造
複合膜を、銀の質量分率を8〜10%の代わりに15〜20%とした以外は実施例1に記載した通りに調製した。得られた粒子を、300〜400nmの厚さを有する銀の層で被覆した。これらの膜は、脆弱であり、粗く且つ孔がたくさんある外観を有した。その走査型電子顕微鏡による観察から、粒の中等度の融合が明らかとなり、更に金属破片と混合しているように見えた。
複合プレートの製造
実施例1に記載したように、幅195mm及び長さ295mmの4つの炭素繊維強化材(200g/m2のHexcel plain 3K HS)を、それらの両面にPA11粒子の粉末をダスティングすることによって含浸させた。こうして得られた4つのプライを積重し、積重物の4つの側面に粘着剤を塗布した後、それを熱圧縮した。これの実現のために、それを幅200mm及び長さ300mmの型に入れ、1シートのテフロン被覆された布帛で各面を覆い、次いで、型を、圧盤を290℃に予熱しておいたCarverプレスに導入し、プライに1.7barの圧力を印加した。次に、圧盤の温度を250℃に低下させ、30秒後、圧力を10barにした。15分後、圧盤を約100℃の温度に冷却した。型から取り出した後、複合プレートを得た。
