SENSORS FOR COMPOSITE PROCESSING

Ultrasonic

A network of 74 sensors — 57 of which were ultrasonic sensors developed by the University of Augsburg (shown as light blue dots in upper RTM mold half) — were used in the T-RTM molding of a thermoplastic composite battery box cover demonstrator for the CosiMo project.
