Abstract
Description
ところが、上述した含浸布のように、先に繊維束を編織してから熱可塑性樹脂をコートすると、コートした熱可塑性樹脂を可塑化しない限り基材の変形が困難となる。この結果、含浸布を任意の形状の成形体に変形させることが困難になる。
しかし、この含浸糸布を構成する1本1本の含浸糸は、一方向に沿って引き揃えられた単繊維を束ねた繊維束を熱可塑性樹脂で被覆して固めたものであり、非常に剛直であって、自由に曲げることができない。つまり、このような曲げにくい含浸糸を編織して形成した含浸糸布は、単繊維の折損を回避するために必然的に目開きが大きくなってしまう。その結果、成形体中での繊維束の密度が不足して、強度の高い成形体を得ることが困難となる虞がある。
さらに、このように曲げにくい含浸糸を用いた編織作業には非常に手間がかかり、含浸糸布の生産性を高めることも難しい場合が多い。
即ち、本発明の含浸糸布の製造方法は、20回/m以上で700回/m以下の撚りを繊維束に加えつつ又は加えた上で、当該繊維束を熱可塑性樹脂が溶融状態で貯留された樹脂槽に含浸させることによって含浸糸を形成し、形成された含浸糸を編織して含浸糸布を得ることを特徴とするものである。
一方、本発明の含浸糸布は、熱可塑性樹脂が表面に被覆された繊維束が互いに編織され、且つ前記繊維束が20回/m以上で700回/m以下で撚られていることを特徴とするものである。
図1A~図1Cに示すように、本発明の実施形態の含浸糸布1は、熱可塑性樹脂5が表面に被覆された繊維束2(強化繊維束)からなる含浸糸3を用いて形成されたものであり、複数本の含浸糸3を編織することで構成されている。つまり、本願発明の含浸糸布1は、樹脂複合材料である含浸糸3を織布することで得られたものである。
含浸糸布1を構成する含浸糸3は、成形体4の機械的特性(引張強度など)を高める繊維束2と、この繊維束2の表面(周囲)を長手方向に亘って被覆する熱可塑性樹脂5とを有している。
繊維束2は上述した単繊維を500tex以上で15000tex以下(JIS L 0101)に束ねたものであり、繊維束2の1本当たりの外径(直径)は0.3mmφ以上で3.0mmφ以下とされている。
上述した含浸糸3を編織する場合は、編み込んでも良いし、織り込んでも良い。例えば、含浸糸3を編み込む場合は、平編み、メリヤス編み、ゴム編み、鎖編み、あるいはガーター編みのような編み方を採用することができる。また、含浸糸3を織り込む場合は、図1に示すような平織り以外にも、斜文織り、サテン織りなどのような織り方を採用することができる。このように編織方法を上述した種類の中で変更することで、含浸糸布1の造形性を向上させることが可能となるからである。
次に、上述した含浸糸布1を実際に製造する方法、言い換えれば本発明の含浸糸布1の製造方法について、説明する。
第1工程7の内容を説明するのに先立ち、まず第1工程7に用いられる製造装置9の説明を行う。
この含浸部12は、可塑化された熱可塑性樹脂5を貯留可能なように、上下方向に軸心を向けた長い有底円筒状に形成されており、上方に向かって開口している。そして、この上側開口から含浸部12の内部に、含浸部12の側方に配備されるボビンから巻き出された複数本の繊維束2が送り込まれている。
含浸部12の下側には上側開口から送り込まれた繊維束2を含浸部12の外側に取り出すダイノズル15が設けられており、このダイノズル15を用いて繊維束2の表面に熱可塑性樹脂5を所定の厚みだけ被覆できるようになっている。また、含浸部12内であって上側開口とダイノズル15の間には、繊維束2を掛け廻された状態で移送する下側のガイドロール(図示略)が、溶融された熱可塑性樹脂5に含浸された状態で配備されている。
このようにして第2工程8で編織により形成した含浸糸布1を所望の形状に沿わせつつ熱プレスすれば、図2に点線で示すように含浸糸布1から成形体4を形成することが可能となる。
また、このような撚りを有する含浸糸3は引張強度などの機械的強度にも優れており、含浸糸布1自体の強度も高くなる。それゆえ、本発明の含浸糸布1を用いれば、図1Cに示すように繊維束2が緻密に配備されかつ強度的にも優れた成形体4を得ることが可能となる。
まず、繊維束2の撚り数が含浸糸3の引張強度に及ぼす影響を検討するため、以下に示す実施例1~実施例3を用意した。
具体的には、実施例1の含浸糸布1に用いられる繊維束2はガラス繊維の単繊維を4620texの番手となるように束ねたものであり、その外径は3.0mmφとされている。また、実施例2の含浸糸布1に用いられる繊維束2はガラス繊維の単繊維を575texの番手となるように束ねたものであり、その外径は1.05mmφとされている。さらに、実施例3の含浸糸布1に用いられる繊維束2は炭素繊維の単繊維を15000texの番手となるように束ねたものであり、その外径は1.7mmφとされている。
一方、繊維束2の撚り数を30回/mとした実施例1~実施例3の含浸糸3に対して、曲げ半径を計測した。この曲げ半径の計測は、例えば曲率半径が異なる円柱に対して含浸糸を曲げていき、損傷がなく曲げられる曲率半径を計測する。この曲率半径を曲げ半径とした。また、比較例として、撚りを加えずに平行のまま単繊維を引き揃えられた繊維束2の周囲に熱可塑性樹脂5を被覆した含浸糸3(撚り数=0回/m)を用いた。実施例1~実施例3及び比較例の含浸糸3に対して曲げ半径を計測した結果を表1に示す。
なお、今回開示された実施形態において、明示的に開示されていない事項、例えば、運転条件や操業条件、各種パラメータ、構成物の寸法、重量、体積などは、当業者が通常実施する範囲を逸脱するものではなく、通常の当業者であれば、容易に想定することが可能な事項を採用している。
