成分B)
成分C
ガラス繊維:直径10μm、ポリエステルのためにサイズ剤処理した、3BのタイプDS3185。
1064nmの波長でのレーザー透過率の測定を、熱電能を測定することにより実施した。測定ジオメトリーは、次のとおりであった:2ワットの全出力を有するレーザービーム(ダイオードでポンピングされた、1064nmの波長を有するNd−YAGレーザー、FOBA DP50)から、ビームスプリッター(Laseroptik GmbH社のタイプ SQ2 無偏光ビームスプリッター)を用いて、参照ビームを角度90°で出力1ワットで分割した。この参照ビームは、参照センサー上に衝突した。ビームスプリッターを通過する、元来のビームの一部は、同様に出力1ワットを有する測定ビームである。この測定ビームは、モード絞り(5.0)によってビームスプリッターの後方で直径0.18μmを有する焦点に焦点合わせされた。レーザー透過率(LT)測定センサーは、焦点の下方へ80mmの距離で位置していた。試験パネルをLT測定センサーの上方へ2mmの距離で配置した。この試験パネルは、エッジゲートを備えた、寸法60×60×2mm3を有する射出成形された試験パネルである。測定は、パネル中心部(2本の対角線の交点)で行なった。射出成形パラメーターを次の値に調節した:
LT=(信号(測定センサー)/信号(参照センサー))×100%
透過スペクトルを300〜2500nmの波長範囲内でウルブリヒト球の測定ジオメトリーを用いて測定した。ウルブリヒト球は、中空球であり、その内面は、幅広のスペクトル範囲に亘って高度に無指向的に(拡散)反射する。ビームがこの球の内面上に衝突した場合には、このビームは、全体的に均一に球内に分布するまで多重に反射する。このビーム積分後、入射角度、影の形成、モード、偏光および別の性質による全ての影響は、平均化されている。球内に取り付けられた検出器は、ウルブリヒト球の構成に応じて拡散透過率だけを記録するか、または指向透過率(gerichteter Transmssion)と拡散透過率との総和(=全透過率)を記録する。
