Ultrasonic sensors and techniques are developed for in-line monitoring of polymer
extrusion, cleanliness of molten metals and liquid flow speed at elevated temperature. Pulse …

The objective of this work was to demonstrate the use of ultrasonics to determine the end-of-
curve for autoclave cured, graphite/epoxy composite laminates. The fundamental benefit of …

The fabrication, evaluation and several applications of metallic buffer rods consisting of a
core and a cladding are presented. The clad rods can have a taper shape and the cladding …

In this paper, new in-line ultrasonic probes for monitoring of polymer melts in polymer
processing are described. The probes are designed to half inch thread as industry standard …

A laser ultrasonic system for real-time cure monitoring of a graphite-epoxy composite is
proposed. The system contains an array of fiberized laser ultrasonic sources, and an …

Materials characterizations using long clad buffer rods with high spatial resolution and at
high temperature are presented. The buffer rods consist of a fine grain steel core and …

Ultrasonic techniques were used to directly monitor the changes in the rheological
properties of polymer matrix composites throughout the cure cycle. These measurements …
