Description
実施例1
上記方法を、酸化物セラミック系プリプレグの製造の例として示す。繊維構造物として、Nextel(商標)610織物タイプDF19(供給業者、3M社)を使用する。加工の前に、これらを空気中で糊抜きする(700℃、2時間の保持時間)。水性泥漿は、67重量%の固体含量を有し、Al2O3-ZrO2粉体混合物(80%のMRS1、Albemarle社;20%のTZ-3Y-E、Krahn Chemie社)、固体に対して1重量%の分散剤Sokalan PA 15、26重量%のグリセリンを有する。該織物を泥漿で含浸し、ドクターブレードを用いて過剰の泥漿を除去する。粘着性のプリプレグを得るために、種々の方法が使用される。変法Aでは、浸透された織物を、気候調節室内で60%の相対湿度及び25℃で24時間にわたり貯蔵する。変法Bでは、50℃(15分間、約10%の相対湿度)で乾燥棚中において部分的な水の除去が行われる。乾燥時間は、その水の除去が変法Aの平衡状態に相当するように選択される(図3を参照)。変法C(図2には示されていない)では、まず50℃(15分間)で部分的な水の除去が行われ、引き続き60%の相対湿度、25℃(24時間)での気候調節室内での貯蔵が行われる。変法Dは、60分間の50℃での水の除去と、60%の相対湿度及び25℃(24時間)での気候調節とから構成される。この場合に、該プリプレグは再湿化されて、平衡状態に至った。
Example 1
The above method is shown as an example of manufacturing an oxide ceramic prepreg. As the fiber structure, Nextel ™ 610 textile type DF19 (supplier, 3M) is used. Prior to processing, these are desizing in air (700 ° C., holding time for 2 hours). Aqueous slurry has a solid content of 67% by weight and is relative to an Al2O3 - ZrO2 powder mixture (80% MRS1, Albemarle; 20 % TZ-3Y-E, Krahn Chemie). It has 1% by weight of the dispersant Sokalan PA 15, 26% by weight of glycerin. The fabric is impregnated with slurry and a doctor blade is used to remove excess slurry. Various methods are used to obtain a sticky prepreg. In modified A, the infiltrated fabric is stored in a climate control room at 60 % relative humidity and 25 ° C for 24 hours. In modified B, partial water removal is performed in the drying rack at 50 ° C. (15 minutes, about 10% relative humidity). The drying time is selected so that the removal of the water corresponds to the equilibrium state of modified A (see FIG. 3). In modified C (not shown in Figure 2), partial water removal is first performed at 50 ° C (15 minutes), followed by climate control at 60% relative humidity and 25 ° C (24 hours). Storage is done indoors. Modified D consists of 60 minutes of water removal at 50 ° C. and 60% relative humidity and climate control at 25 ° C. (24 hours). In this case, the prepreg was re-humidified and reached an equilibrium state.
粘着性のプリプレグを得るために、浸透された織物を、気候調節室内で60%の相対湿度及び25℃で20時間にわたり貯蔵する。 To obtain a sticky prepreg, the infiltrated fabric is stored in a climate control room at 60 % relative humidity and 25 ° C. for 20 hours.
