Abstract:

SMARTweave SW was patented in May 1993 as an electromagnetic method to monitor the flow of resin in composite manufacturing processes. It has been found to be very rapid and effective for this purpose, and its uses have expanded since this date. Using a Labview software package and 16 conductive nodes, both processes and properties of composite materials can be characterized. SW has specifically been used at our laboratory to investigate the resin transfer molding RTM process. The speed of entry of the resin for different composite fabrics can be visually studied and adjusted. Composites are typically difficult to examine with nondestructive evaluation NDE, so this new technique is a valuable addition. There are eight excitation probes and eight sensor probes, unlike the usual one excitation probe and one sensor probe.
