Resin flow front measuring system for use with electrically conductive reinforcement determines capacitance changes between a condensor plate and reinforcement

摘要

The fiber reinforcement(5) is placed on an electrically isolated surface of a plate(1) of a plate condensor and the change of capacitance between the plate and the reinforcement or between the plate and a similarly isolated plate(2) in contact with the reinforcement is measured with a capacitance measuring circuit as the resin flow front advances through the reinforcement.
