Description
図1Aは本発明の一実施例のフィルムスタッキング法による成形体の製造方法を示す平面図、図1Bは同製造方法の断面図である。メタルフレーム2に、亜麻(リネン)繊維からなる紡績糸1a,1bを図1Aのように一方向に巻き付けた。紡績糸の太さ(繊度)は130tex、巻きつけ本数は、幅20mmに対し132本、巻きつけ重量3.1gであった。なお、図1Aにあるとおりメタルフレーム2に一定間隔を置いて2カ所巻き付けた。紡績糸の撚り数はインチあたり12回(472.4T/m)、分解温度は約200℃であった。この巻きつけた紡績糸に、図1Bに示すように、融点151℃、厚さ0.2mm(200μm)のポリプロピレン(PP)フィルム3a〜3fを両面及び中間(上下の糸間)に配置し、熱プレス金型4,5によって亜麻(リネン)紡績糸とPPフィルムを溶融一体化させた。金型温度は160〜190℃とし、圧力は4MPa、加熱加圧時間は20分間とした。紡績糸の割合は約70質量%であった。
次に、水分の影響について検討した。天然繊維は吸水性が高く、水分により力学的物性が大きく変化する。また成形時に水分が存在すると、未含浸領域となると考えられる。従来は水分の存在は好ましくないと考えられていた。
(1)乾燥:60℃、24時間乾燥
(2)平衡水分率(25℃、相対湿度65%室内環境放置。平衡水分率の状態。)
(3)吸水(80℃、飽和水蒸気中、120時間)
前記サンプルの物性を表2に示す。
(1)乾燥では糸内部とマトリックスの含浸状態は良い。
(2)放置では糸内部へのマトリックス樹脂の含浸状態が比較的良好である。
(3)吸水状態では、糸内部に未含新領域である亀裂がある。糸内部の水がマトリックス樹脂の含浸の妨げになったと考えられる。
本発明の応用例を図3に示す。図3は多軸挿入たて編物の概念斜視図である。複数の方向に各々配列された亜麻糸紡績糸1a〜1fは、編針6に掛けられたステッチング糸7,8によって厚さ方向にステッチング(結束)され、一体化されている。このような多軸挿入たて編物を繊維補強材とし、熱可塑性樹脂と一体化成形することもできる。
