本発明において繊維状担体は、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)若しくはポリエステル、天然繊維若しくは鉱物繊維材料、例えば玄武岩繊維、又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及び/又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、又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材部材が、様々な繊維状担体からのプリプレグによって製造できる。
原則的には、あらゆる粉末状の反応性ポリウレタン組成物がマトリッ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官能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、つまり内的に(intern)ブロックされた、及び/又はブロック化剤でブロックされたジイソシアネート又はポリイソシアネート(硬化剤a、成分aともいう)との混合物から成る。
a)脂肪族、(環式)脂肪族、又は脂環式のウレトジオン基含有ポリイソシアネート、及びヒドロキシ基含有化合物からの重付加化合物をベースとする少なくとも1つのウレトジオン基含有硬化剤、
ここで前記硬化剤は40℃未満で固体状で、125℃超では液状で存在し、その遊離NCO含分は5質量%未満であり、そのウレトジオン基含分は3〜25質量%であり、
b)40℃未満では固体で、125℃超では液状で存在し、OH数が20〜200mgKOH/gの、少なくとも1つのヒドロキシ基含有ポリマー、

A)少なくとも1つの繊維状担体、及び
B)マトリックス材料としての、少なくとも1つの反応性粉末状ポリウレタン組成物、好ましくはウレトジオン基含有ポリウレタン組成物、
から構成されているプリプレグを、160℃超の温度、好ましくは180℃超、場合により圧力及び/又は真空を適用して製造する、複合材部材の製造方法である。
使用される実験室用散布装置(Villars Minicoater 200)の図1
使用されるガラス繊維の単一方向布/織布:
以下、ガラス繊維の単一方向布/織布を実施例で用いるが、これ以降はタイプI、タイプIIと呼ぶ。
DSC試験(ガラス転移点測定と、反応エンタルピー測定)を、DIN 53765準拠のMettler Toledo DSC 821 eによって行った。
プリプレグの貯蔵安定性は架橋反応の反応エンタルピーによって、DSC調査により測定される。その結果は、図2、及び図3に示されている。
複合材部材は、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した。散布装置で製造された、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した。圧力は、常圧〜450barの間で変えた。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有利であると実証できる。1つの例では、溶融相の間のプレス温度(90℃)を110℃に上げ、圧力は3分間の溶融フェーズ後、440barに上げ、引き続き150〜440barの間で動的に変え(それぞれ一分間を7回)、この際に温度は連続的に140℃に上げた。引き続き温度を170℃に上げ、同時に圧力を350barで、30分後にプレス型から複合材部材を取り外すまで、このレベルを維持した。
