Abstract

It is useful to detect defects of a preform for resin transfer molding before and after placement into the mold. To conduct this test, the gas flow method has been developed. This method not only measures permeability but also detects defects utilizing the pressure readings obtained from the gas flow test. This paper introduces the methodology and examine the applicability to actual processes.

RTM 공정의 성공적인 수행을 위해 프리폼의 삽입 후 혹은 삽입 전의 상태를 점검하는 과정은 매우 유용하다. 이를 위해 기체를 주입하여 유량과 압력 측정을 통해 프리폼의 투과성 계수를 측정하고 결함을 탐지하는 기법이 최근 연구되어 왔다. 본 논문에서는 이 기법을 소개하고 적용성을 검토해 본다.
