Description
成形により得られた厚み4mm×幅10mm×長さ80mmのバーについて、JIS−K7171に準拠して下記条件で測定を行った。試験速度は2mm/min、支点間距離は64mmとした。
成形により得られた厚み4mm×幅12.7mm×長さ63.5mmのバーについて、JIS−K7110に準拠して下記条件で測定を行った。ノッチ加工の回転数は400rpm、ノッチ加工の送り速度は120mm/min、ハンマー容量は5.5J、測定温度は23℃と−40℃とした。
成形により得られた厚み3.2mm×幅10mmのダンベル型バーについて、JIS−K7161に準拠して試験速度50mm/minで測定を行った。
成形により得られた100mm×100mm×厚さ3mmの平板の表面を目視にて観察し、以下の基準で評価した。
△:開繊していない繊維の束が少し見られるか又は平板表面に少し凸凹がある。
×:開繊していない繊維の束が多数見られ、平板表面が荒れている。
ポリプロピレンとPET長繊維成分とタルクとを表1に示す配合で使用し、引き抜き成形を行い、長繊維強化ポリオレフィン樹脂ペレットを製造した。製造装置としては、クロスヘッドダイを有する二軸押出機(日本製鋼所(株)製「TEX30」、L/D=42、シリンダー径30mm、シリンダー温度:190〜220℃、クロスダイヘッド温度:220℃)を使用した。なお、ペレット長は8mmとなるように調節した。次いで、得られた長繊維含有ポリオレフィン系樹脂ペレットを、射出成形機に供し、シリンダー温度210℃、金型温度70℃、背圧10kg/cm2、スクリュー回転数50rpmにて、平板およびバーを成形した。評価結果を表1及び表2に示す。
