Fiber Tensile Module
Tensile Experiments
— down to the µN-Range
The outer
dimensions of the Fiber Tensile Module are 80 x 100 x 22 mm3, it is mounted to the SEM or light microscope specimen stage "like a
large specimen". It allows in-situ observation of tensile testing
experiments at extremely low forces, yet very high load resolution (down to
1×10-5 N). The tensile speed range is 0,1 to 20 µm/s. These features, coupled
with maximum stiffness of this substage, allow very accurate measurements on
fibers of down to 2.5 µm diameter, and several millimeters length. The specimens
can be observed statically or dynamically at magnifications well beyond
10 000 x in daily routine work.
The load is
measured by the principle of frequency variations on a spring-loaded metal
wire. The displacement is taken by a differential transformer (LVDT).
The enlarged view
shows the specimen holder, which is a pair of ceramic tubes, ground down to
half their diameter (red tips). One side is attached to a parallel sled, driven
by a combination of DC-tacho-motor/angular encoder for precise recognition of
the displacement. A fine tungsten wire touches the specimen from underneath at
90 degrees. This wire allows heating up the specimen locally.
