このように、連続繊維強化熱可塑性樹脂シートにおける熱可塑性樹脂の含有率が適当な範囲内で調整されていると、詳細を後述する溶媒除去工程によっても除去されない残留溶媒の量を抑制し易く、また、連続繊維強化熱可塑性樹脂シートの弾性、強度等の性状を良好なレベルとすることができる。
本発明で使用される連続繊維として、炭素繊維、ナイロンあるいはアラミド等のポリアミド繊維、ポリエステル繊維等の有機繊維、及び、ガラス繊維などの無機繊維などが挙げられ、炭素繊維が好ましい。
炭素繊維として、ポリアクリロニトリル(PAN)繊維あるいはピッチ繊維等に由来するものであって、PAN繊維を原料とするPAN系炭素繊維であってもピッチ系炭化水素であってもよい。炭素繊維における炭素の含有量は、90質量%以上であることが好ましく、95質量%以上であることがより好ましく、実質的に100質量%であることがさらに好ましい。
また、連続繊維の形態としては、単一ストランド、一方向シート、織物シート、多軸積層シート等が挙げられる。
連続繊維として、繊維束(フィラメント)に含まれる単繊維数、フィラメントの束(トウ)に含まれるフィラメント数やその構成が様々なものが採用され得るのであり、本発明において、種々多様な連続繊維を使用することができる。
また、連続繊維強化熱可塑性樹脂シートの全質量を基準とする連続繊維及び熱可塑性樹脂の合計質量の割合は、80~100質量%であることが好ましく、90~100質量%であることがより好ましく、95~100質量%であることがさらに好ましく、98~100質量%であることが特に好ましい。連続繊維強化熱可塑性樹脂シートは、好ましくは、実質的に連続繊維及び熱可塑性樹脂のみからなる。
連続繊維強化熱可塑性樹脂シートの製造工程には、詳細を後述するように、熱可塑性樹脂を含ハロゲン有機溶媒に溶解させた溶液を連続繊維に含浸させる含浸工程が含まれるため、連続繊維強化熱可塑性樹脂シートにおいては、含ハロゲン有機溶媒等の溶媒が若干量、含まれ得る。このように、連続繊維強化熱可塑性樹脂シートに含まれ得る残存含ハロゲン有機溶媒の含有率は、連続繊維強化熱可塑性樹脂シートの全質量を基準として1000質量ppm以下であることが好ましく、1000質量ppm以下であることが好ましく、800質量ppm以下であることがより好ましく、500質量ppm以下であることがさらに好ましく、200質量ppm以下であることが特に好ましく、150質量ppm以下、100質量ppm以下あるいは100質量未満であることが特に好ましい。
本発明の製造方法によれば、溶媒除去工程の直後、あるいは製造された直後の連続繊維強化熱可塑性樹脂シートにおいて、自然乾燥が行われていない状態であっても、残存含ハロゲン有機溶媒の含有率を上述の範囲内に調整することができる。

本発明の連続繊維強化熱可塑性樹脂シートは、単層のシートであってもよく、また、複数のシートが直接積層された積層シートであってもよい。特に、連続繊維強化熱可塑性樹脂シートのみが複数、積層されている積層シートであることがより好ましい。
本発明の連続繊維強化熱可塑性樹脂シートを積層させて積層シートを製造する工程としては、プレス成形工程などが挙げられる。
連続繊維強化熱可塑性樹脂シートの製造工程には、熱可塑性樹脂を含ハロゲン有機溶媒に溶解させた溶液を連続繊維に含浸させる含浸工程、及び、連続繊維から含ハロゲン有機溶媒を赤外線の照射により除去する溶媒除去工程が含まれる。このような溶媒除去工程により、連続繊維強化熱可塑性樹脂シートの中間材料であって、溶媒を含む熱可塑性樹脂が含浸された連続繊維を効率的に乾燥させることができる。
連続繊維強化熱可塑性樹脂シートの製造方法は、溶液製造工程を含んでいてもよい。
熱可塑性樹脂溶液は、上述の熱可塑性樹脂等を含ハロゲン有機溶媒に溶解させる溶液製造工程によって調製されることが好ましい。熱可塑性樹脂は、少なくともポリカーボネート樹脂及びポリアリレート樹脂のいずれかを含むが、これらの樹脂の製法は特に限定されない。例えば、ホスゲン法(界面重合法)、溶融エステル交換法などの様々な製法で製造されたポリカーボネート樹脂を用いることができる。
例えば、以下のような反応条件の界面重合法によりポリカーボネート樹脂を製造できる。すなわち、ジクロロメタン、及びアルカリ水溶液の存在下で、通常pHを10以上に保ち、2価フェノール及び末端停止剤としての1価フェノール、必要に応じて2価フェノールの酸化防止のために用いられる酸化防止剤、及びカーボネート結合剤としてのホスゲンまたはトリホスゲンを含む反応原料を混合させた後、第三級アミンまたは第四級アンモニウム塩等の重合触媒を添加して界面重合を行い、得られた樹脂溶液を精製することによってポリカーボネート樹脂溶液を得ることができる。末端停止剤の添加のタイミングは、ホスゲン化の開始時から重合反応開始時までの間であれば、特に限定されない。尚、反応温度は0~35℃であり、反応時間は数分~数時間である。
熱可塑性樹脂溶液を形成するための含ハロゲン有機溶媒として、様々なものが用いられ得る。例えば、合計炭素数が3以下、好ましくは2以下、より好ましくは1である含ハロゲン有機溶媒、1分子中ハロゲン原子を3個以下、好ましくは2個以下含むもの、ハロゲンとして塩素、フッ素及びヨウ素のいずれか、好ましくは塩素及びフッ素のいずれかを含むもの、などが用いられ得る。
含ハロゲン有機溶媒の好ましい具体例としては、ジクロロメタン、クロロメタン、トリクロロメタン、トリクロロエチレン、テトラクロロエチレンなどが挙げられ、ジクロロメタンが含ハロゲン有機溶媒としてより好ましい。
含浸工程は、ポリカーボネート樹脂溶液等の熱可塑性樹脂溶液を連続繊維に含浸させる工程である。含浸工程における熱可塑性樹脂溶液の含浸の方法は特に限定されず、溶液を収容した槽中に繊維を浸漬させる方法、溶液を噴霧した槽中に繊維を通過させる方法、および繊維に対して溶液を噴射させる方法などの各種の方法を取り得る。これらの中でも、溶液を収容した槽中に連続繊維を浸漬させる方法が最も簡便かつ均一な溶液の付着を可能とするため好ましい。
溶媒除去工程において、赤外線の照射装置、例えば赤外線を照射可能なヒーターを用いて、連続繊維強化熱可塑性樹脂シートの中間材料である、熱可塑性樹脂溶液を含む連続繊維を乾燥させる。ヒーターと乾燥対象である連続繊維との距離、すなわち、ヒーターにおける赤外線の照射面と連続繊維の被乾燥面との距離は、100mm以上410mm以下であることが好ましい。ヒーター及び乾燥対象の連続繊維の間の距離は、150mm以上380mm以下であることがより好ましく、180mm以上360mm以下であることがさらに好ましく、200mm以上320mm以下、例えば220mm以上300mm以下であることが特に好ましい。
また、溶媒除去工程において、2μm~20μmの波長領域を含む遠赤外線を照射するヒーターを用いることが好ましく、ヒーターは、より好ましくは3μm~15μmの波長領域を含む赤外線を照射可能であり、さらに好ましくは、5μm~12μmの波長領域を含む赤外線を照射可能である。
さらに、溶媒除去工程においては、ピーク波長が2.0μm~6.0μmである遠赤外線の使用が好ましく、より好ましくは、遠赤外線のピーク波長が2.5μm~5.5μmであり、さらに好ましくは、遠赤外線のピーク波長は3.0μm~5.2μmであり、特に好ましくは、遠赤外線のピーク波長は3.5μm~5.0μmあるいは4.0μm~4.9μmである。
なお上述のピーク波長の値は、ヒーターの赤外線照射面から照射された直後の値であり、赤外線の波長は、ヒーター及び乾燥対象である連続繊維との間の距離に応じて変化し得るものの、上述の範囲の距離と、上述の範囲の波長領域またはピーク波長の赤外線を照射すると、溶媒除去を効率化できる。
また、溶媒除去工程において、ヒーターの最大エネルギー密度は、20~200kW/m2程度であることが好ましく、30~150kW/m2あるいは35~120kW/m2であることがさらに好ましく、45~120kW/m2あるいは50~150kW/m2であることがより好ましい。また、ヒーターの最大エネルギー密度は、40~100kW/m2あるいは45~80kW/m2であってもよい。
連続繊維強化熱可塑性樹脂シートの製造方法においては、溶媒除去工程の後に連続繊維強化熱可塑性樹脂シートにおける残留含ハロゲン有機溶媒の含有率を測定する測定工程をさらに有することが好ましい。
上述のように、連続繊維強化熱可塑性樹脂シートにおける残留含ハロゲン有機溶媒の含有率は低い方が好ましいため、測定工程によって所望の性状の連続繊維強化熱可塑性樹脂シートが製造されたか否か、確認することができる。
連続繊維強化熱可塑性樹脂シートの製造方法においては、溶媒除去工程の後に連続繊維強化熱可塑性樹脂シートにおける残留含ハロゲン有機溶媒の含有率を所定の閾値と比べる比較工程をさらに有することが好ましい。
上述のように、連続繊維強化熱可塑性樹脂シートにおける残留含ハロゲン有機溶媒の含有率を抑制すべく、所定の基準値、主として上限値(例えば上述の1000質量ppmなど)を閾値として設定しておき、実際の残留含ハロゲン有機溶媒の含有率と比較することにより、所望の性状の連続繊維強化熱可塑性樹脂シートが製造されたか否か、確認することができる。
後述する実施例及び比較例にて得られた炭素繊維強化樹脂プリプレグにおける樹脂質量含有率を、JIS K 7075に基づき求めた繊維質量含有率をもとに算出した。すなわち、炭素繊維強化樹脂プリプレグにおける繊維質量含有率(質量%)の値を100(%)から減じた値(質量%)を樹脂質量含有率とした。

ポリカーボネート樹脂(PC-1)15質量部をジクロロメタン85質量部に溶解し、ポリカーボネート樹脂溶液を調製した。
ポリアクリロニトリル由来の連続炭素繊維による2/2綾織の炭素繊維織物(東レ株式会社製トレカ(登録商標)クロスCO6347B)を6.0cm×16.0cmの大きさ(厚さ0.22mm;重量198g/m2))にカットし、ディップコーターを用いて0.6m/minの引き上げ速度でポリカーボネート樹脂溶液の含浸を行った。含浸後の炭素繊維織物であるプリプレグ中間材料(プリプレグ基材)の両方の表面に、それぞれ向かい合わせた一対の遠赤外線ヒーターパネル(遠赤外線株式会社ノリタケカンパニーリミテド製・電気式セラミックヒーターPLC(PLC-328))でプリプレグ中間材料を5分間乾燥させ、炭素繊維強化熱可塑性樹脂プリプレグを得た。遠赤外線ヒーターの周囲はアルミ板で囲い、ヒーターパネルとプリプレグ基材との距離およびヒーター温度については表1に記載した通りに、溶媒除去工程を実施した。
なお、溶媒除去工程においては、遠赤外線ヒーターパネル1枚の赤外線の照射面の面積は0.0144m2(12cm×12cm)であり、略同一面に沿うように並べて配置させたプリプレグ中間材料2枚の表側と裏側にそれぞれ対向するように4枚の遠赤外線ヒーターパネルを用いた。2枚のプリプレグ中間材料における含浸部分、すなわち、溶媒除去の対象となる被乾燥面は0.0060m2(10cm×6cm)であった。このため、連続繊維の被乾燥面の面積に対するヒーターパネルにおける遠赤外線の照射面の面積の割合(被乾燥面の面積(m2)/遠赤外線の照射面の面積(m2)×100(%))は、約41.7%であった。
また、表1における「赤外線ヒーター温度」の欄の値は、ヒーターにおける赤外線を放射する発熱体の温度を意味するのであり、表2においても表1と同様である。

ポリカーボネート樹脂の種類、ヒーターパネルとプリプレグ基材との距離およびヒーター温度のいずれかを表1に記載の通り変更した以外は、実施例1と同様にして炭素繊維強化樹脂プリプレグを作製し、評価を行った。
評価結果を表1または表2に示す。実施例1-1~1-7の結果については、実施例1及び2のいずれにも含まれる上述の実施例1の結果とともに、表2に示す。
また、赤外線を照射するヒーターと連続繊維の被乾燥面との距離、赤外線のヒーター温度、乾燥時間などの溶媒除去工程における諸条件を調整した実施例では、連続繊維の乾燥がより効率的に行われること、及び、樹脂溶液の濃度や含浸速度など、溶媒除去工程の前段階にある含浸工程の諸条件を調整することによっても、連続繊維の乾燥が一段と効率化されることが確認された(表1及び表2参照)。
