Description
A)少なくとも1種の繊維状の支持体と、
B)少なくとも1種の溶剤(C)中の、マトリクスとしての、少なくとも1種の反応性のポリウレタン組成物と
その際、前記ポリウレタン組成物は、主として、バインダーとしての、イソシアネートに対して反応性の官能基を有するポリマーb)と、硬化剤としての、内部ブロック化されたおよび/またはブロック化剤でブロック化されたジイソシアネートもしくはポリイソシアネートa)とからの混合物を含有する、
から構成されるプリプレグの製造方法であって、
I. 少なくとも1種の溶剤(C)中の、反応性のポリウレタン組成物(B)を製造し、
II. 繊維状の支持体(A)を、(B)の溶液で直接的に含浸させ、
III. 溶剤を除去する
ことによって行う前記製造方法である。
本発明において繊維状の支持体は、繊維状材料から成る(しばしば、強化繊維とも呼ばれる)。一般的には、繊維から成るあらゆる材料が適しているが、好ましくはガラス、炭素、プラスチック、例えばポリアミド(アラミド)もしくはポリエステル、天然繊維もしくは鉱物繊維材料、例えば玄武岩繊維、またはセラミック繊維からの繊維状材料(酸化アルミニウムベースおよび/または酸化珪素ベースの酸化物繊維)を使用する。複数の繊維の混合物、例えばアラミド繊維とガラス繊維との織布の組み合わせ、または炭素繊維とガラス繊維との組み合わせも、用いることができる。同様にハイブリッド複合部材が、様々な繊維状の支持体からのプリプレグによって製造できる。ガラス繊維は主に、相対的に値段が低いことから、もっともよく使用される種類の繊維である。ここで原則的には、ガラスベースのあらゆる種類の強化繊維が適している(E−ガラス繊維、S−ガラス繊維、R−ガラス繊維、M−ガラス繊維、C−ガラス繊維、ECR−ガラス繊維、D−ガラス繊維、AR−ガラス繊維、または中空ガラス繊維)。炭素繊維は一般的に、高性能複合材料で使用され、ここではまたガラス繊維よりも低い密度と同時に高い強度が重要な要素である。炭素繊維(カーボンファイバーとも)は、炭素含有出発材料から工業的に製造される繊維であり、黒鉛状に配置された炭素への熱分解により変換されるものである。等方性と異方性の区別は次のように行う。等方性繊維は強度が非常に弱く、技術的意義がより低い。異方性繊維は強度が高く、同時により僅かな破断点伸びで高い剛性を示す。ここで天然繊維とは、植物性材料および動物性材料から得られる、あらゆるテキスタイル繊維と繊維材料である(例えば木材繊維、セルロース繊維、木綿繊維、麻繊維、ジュート繊維、亜麻繊維、サイザル麻繊維、竹繊維)。アラミド繊維は炭素繊維に似て負の熱膨張率を有する。つまり、加熱時により短くなる。その比強度と弾性率は、炭素繊維のものよりも明らかに低い。マトリクス樹脂の正の膨張率と結びついて、寸法精度が高い部材が製造できる。炭素繊維で強化されたプラスチックと比べて、アラミド繊維複合材料の圧縮強度は、明らかにより低い。アラミド繊維について公知の商品名は、DuPont社のNomex(登録商標)とKevlar(登録商標)、または帝人のTeijinconex(登録商標)、Twaron(登録商標)、およびTechnora(登録商標)である。特に適しており、かつ好ましいのは、ガラス繊維、炭素繊維、アラミド繊維、またはセラミック繊維からの支持体である。繊維状材料とは、テキスタイルの繊維品(Flaechengebilde)である。適しているのは、フリース、同様にいわゆる編物、例えば編み生地およびニット、また非メッシュ状の結合体、例えば平織り布、単一方向布、または斜め織り布からのテキスタイル平面構造体である。
原則的に、あらゆる反応性のポリウレタン組成物も、室温までで貯蔵安定性のその他の反応性のポリウレタン組成物もマトリクス材料として適している。適切なポリウレタン組成物は本発明によれば、NCO基に対して反応性の1つの官能基を有するポリマーb)(結合剤、樹脂ともいう)と、一時的に不活性化された、つまり内部ブロック化された、および/またはブロック化剤でブロック化されたジイソシアネートまたはポリイソシアネート(硬化剤、成分a)ともいう)との混合物から成る。
a)少なくとも1種のウレットジオン基を有する硬化剤であって、脂肪族の、(環式)脂肪族のもしくは脂環式のウレットジオン基を含むポリイソシアネートとヒドロキシル基を有する化合物とからの重付加化合物を基礎とする硬化剤と、
その際、該硬化剤は、40℃を下回ると固体形で存在し、125℃を上回ると液体形で存在し、5質量%未満の遊離NCO含量を有し、3〜25質量%のウレットジオン含量を有する、
b)少なくとも1種のヒドロキシル基を有するポリマーであって、40℃を下回ると固体形で存在し、125℃を上回ると液体形で存在し、かつ20〜200mg KOH/gのOH価を有するポリマーと、
c)任意に、少なくとも1種の触媒と、

d)以下の

その際、該硬化剤は、40℃を下回ると固体形で存在し、かつ125℃を上回ると液体形で存在し、かつ5質量%未満の遊離NCO含量を有し、かつ3〜25質量%のウレットジオン含量を有する、
b)少なくとも1種のヒドロキシル基を有するポリマーであって、40℃を下回ると固体形で存在し、かつ125℃を上回ると液体形で存在し、かつ20〜200mg KOH/gのOH価を有するポリマーと、
c)対イオンとしてのハロゲンイオン、水酸化物イオン、アルコレートイオンまたは有機もしくは無機の酸アニオンを有する第四級アンモニウム塩および/または第四級ホスホニウム塩から選択される少なくとも1種の触媒0.1〜5質量%と、

反応性のポリウレタン組成物を以下の調合で、プリプレグ及び複合材の製造のために使用した。
DSC試験(ガラス転移点測定と、反応エンタルピーを測定)を、DIN 53765準拠のMettler Toledo DSC 821eによって行う。
例1もしくは例2からのプリプレグのDSC調査により以下の図1および図2からうかがえる18日後もしくは40日後に測定された結果が得られる。測定された反応エンタルピーは、貯蔵の過程で大きく低下しない。これは、マトリクス材料の反応性を裏付けている。
複合部材は、当業者に公知のプレス技術によって複合材プレス機で製造する。直接含浸によって製造された、均質なプリプレグを卓上プレス機でプレスして複合材料にした。この卓上プレス機はSchwabenthan社のPolystat 200 Tであり、これを用いてプリプレグを120〜200℃の温度で相応する複合材プレートにプレスする。圧力は、常圧〜450barの間で変える。動的なプレス、つまり付与圧力の変更は、部材の大きさや厚さ、及びポリウレタン組成物、ひいては加工温度での粘度調整に応じて、繊維を濡らすために好ましいと見なすことができる。
