Unique Configuration Enables Standard Compression Tests on
Composite Materials
Micro-Measurements®, a Vishay Precision Group, Inc.
(NYSE: VPG) brand, today announced the release of three
CEA-Series strain gages designed to perform standard compression
tests on polymer matrix composite materials. The new sensor
patterns feature a unique configuration that is ideal for any
strain measurement requiring close proximity to one-sided features,
such as weld joints, structural discontinuities or stress risers
like holes and cracks.
“Structural designers have told us that finding the compression
strength of composite materials is necessary and is the subject of
ASTM Standard Test Method D6641,” said Bob Watson, director of
engineering, Micro-Measurements®. “The loading device recommended
for use in this standard provides a 12.7 mm (0.5 in.)
test section length, and a test section width range of 12.7 –
30 mm (0.5 – 1.2 in.), making our new UB pattern geometry
ideal for this testing.”
The 062UB, 125UB and 250UB patterns are designed with both
solder tabs placed on one side of the linear sensing grid, which
allows these foil strain sensors to be properly oriented on the
composite specimen, keeping the sensing grid centered in the test
zone.
Available in 350 ohm to minimize self-heating, the UB
patterns are made in the popular CEA-Series construction, which
features a thin, flexible, cast polyimide carrier backing and
encapsulation, and rugged, copper-coated solder tabs that provides
quick and simple soldering. The UB patterns are also available with
optional pre-attached lead wires, eliminating the chance of heat
damage to the test specimen during soldering.

125UB and 250UB patterns is available at
