Abstract
Description
ピンホールの利用により緻密化に及ぼされる効果を、CVI法における穴を有するプリフォームの使用と関連づけてモデル化した。この計算においては、繊維充填率が35%で、気孔直径が約6μm〜約10μmだと仮定した。表1では、2ミル(約50.8μm)のピンホール径を有するものとしてモデル化した異なる4つの例示的なプリフォームに関して、ピンホール間隔(中心間、単位はミル)に対するピンホール体積分率(単位は%)が示されている。
本開示による穴を内包するセラミックマトリックス複合材製プリフォームの様々な実施形態と、先行開示のプリフォームとを比較しておいた。図3は、本開示の実施形態のプリフォーム穴間隔(mm)及び穴径(mm)と、米国特許第5405560号明細書及び米国特許第8216641号明細書で記述されたプリフォーム穴間隔及び穴径とを比較したグラフである。図4は、本開示の実施形態のプリフォーム穴密度(1cm2当たりの穴)及び面積分率(%)と、米国特許第5405560号明細書及び米国特許第8216641号明細書で記述されたプリフォーム穴密度及び面積分率とを比較したグラフである。
