Description
図２に示す実施形態においては、任意のバリア層２０、２２を中間層１６、及び第１層１２と第２層１４の間にそれぞれ形成する。バリア層２０、２２は、例えば非限定的にエポキシ樹脂と化学的及び熱的に共存可能である別の熱可塑性材料、又はナイロン布（Ｃｅｒｅｘ）等の材料を含むことができる。このバリア層２０、２２は、中間層１６におけるＶＥＭの移動及び層１２、１４でのエポキシ樹脂の移動を制限するように機能することにより、これら２つの材料が分離され混合が避けられる。ＶＥＭとエポキシ樹脂の混合により、中間層１６の減衰特性が低下する可能性がある。満足な結果をもたらす一実施形態では、バリア層２０、２２の厚さは０．０００５〜０．００２インチの間であってよい。バリア層２０、２２はまた、ＶＥＭ膜が自動テープ敷設装置を使用して取り出されるのに好適になるように働く。各バリア層２０、２２は比較的剛性であるため、自動の繊維配置製造工程で使用される際に、マルチヘッドテープレイヤー（ＭＨＴＬ）装置を使用して１本のロールからＶＥＭ膜をはがすことが可能になる。
