Description
ここで、Wは誘電損失エネルギー、kは定数、fは周波数、v2は電位傾度、εは誘電率、tanδは誘電正接を表す。式(1)から、誘電率及び誘電正接が大きい程、また周波数が高い程、誘電損失が大きくなり、前記樹脂成形品の発熱が大きくなることがわかる。そこで、前記樹脂成形品には、高い衝撃強さに加えて、さらに、低い誘電率及び誘電正接が求められている。
表1に示す2種類のガラス組成を用いた。ここで、組成1は本発明のガラス繊維強化樹脂成形品に用いるガラス繊維のガラス組成であり、組成2はEガラス組成に相当する。
[樹脂]
ポリアミド樹脂(表中、PAを表記する)として、UBE NYLON 1015B(商品名、宇部興産株式会社製)を用いた。
ガラス繊維強化樹脂成形品の引張強度は、ISO527−1,2に準拠して測定した。
ガラス繊維強化樹脂成形品のノッチ付きシャルピー衝撃強さは、ISO179に準拠して測定した。
ガラス繊維強化樹脂成形品の誘電率は、JIS C 2565に準拠して測定した。測定周波数は10GHzである。
ガラス繊維強化樹脂成形品の誘電正接は、JIS C 2565に準拠して測定した。測定周波数は10GHzである。
表2に示すとおり、前記組成1又は2を備える円形断面又は長円形断面を有するガラス繊維と、ポリアミド樹脂とからなるガラス繊維強化樹脂成形品について、ガラス繊維が前記組成1を備え、円形断面を備える場合を実施例1、ガラス繊維が前記組成1を備え、長円形断面を備える場合を実施例2、ガラス繊維が前記組成2を備え、円形断面を備える場合を比較例1、ガラス繊維が前記組成2を備え、長円形断面を備える場合を比較例2として、該ガラス繊維強化樹脂成形品の引張強度、ノッチ付きシャルピー衝撃強さ、誘電率及び誘電正接を評価した。
表2に示されるとおり、本発明に規定されるガラス組成を備える実施例1のガラス繊維強化樹脂成形品は、Eガラス組成を備える以外は実施例1と全く同一の構成を備える比較例1のガラス繊維強化樹脂成形品と比較して、引張強度は同等(比較例1を基準として差が±5.0%未満)であるが、ノッチ付きシャルピー衝撃強さが向上(比較例1を基準として上昇率が5.0%以上)しており、誘電率及び誘電正接が著しく低減(比較例1を基準として低下率が10.0%以上)していた。
表3に示すとおり、前記組成1又は2を備える長円形断面を有するガラス繊維と、ポリブチレンテレフタレート樹脂とからなるガラス繊維強化樹脂成形品について、ガラス繊維が前記組成1を備える場合を実施例3、ガラス繊維が前記組成2を備える場合を比較例3として、該ガラス繊維強化樹脂成形品の引張強度、ノッチ付きシャルピー衝撃強さ、誘電率及び誘電正接を評価した。
表3に示されるとおり、本発明に規定されるガラス組成を備える実施例3のガラス繊維強化樹脂成形品は、Eガラス組成を備える以外は実施例3と全く同一の構成を備える比較例3のガラス繊維強化樹脂成形品と比較して、引張強度は同等(比較例3を基準として差が±5.0%未満)であるが、ノッチ付きシャルピー衝撃強さが向上(比較例3を基準として上昇率が5.0%以上)しており、誘電率が低減(比較例3を基準として低下率が5.0%以上)しており、誘電正接が著しく低減(比較例3を基準として低下率が10.0%以上)していた。
