Claims (3)
- 経糸と緯糸とで織成され繊維強化樹脂に使用される織物の該経糸と緯糸とで囲繞された開口部の開口率(開口部の開口面積の総和/測定範囲全面積)を測定する開口率測定装置であって、前記織物の一面側に該織物に向けて測定用光を照射する発光部が配置され、更に、前記織物の他面側に前記測定用光が照射された該織物を撮影する撮影部が配置され、この発光部及び撮影部は前記発光部からの前記測定用光が前記撮影部に略垂直に入射する状態を保持するように同期移動しながら該撮影部により所定の測定範囲で撮影が行われるように構成され、前記撮影部で撮影され該撮影部から入力される撮影画像データを画像解析して前記開口部の前記開口面積の総和を算出し該開口面積の総和を用いて前記開口率を算出する算出機構を備えていることを特徴とする開口率測定装置。
- 請求項1記載の開口率測定装置において、前記算出機構は前記開口率及び該開口率の標準偏差を算出するように構成されていることを特徴とする開口率測定装置。
- 請求項1,2いずれか1項に記載の開口率測定装置において、前記算出機構としてパソコンが採用されていることを特徴とする開口率測定装置。
