Shape memory alloys (SMA) represent a category of smart materials and are widely used as actuators
for many applications ranging from aircraft-automotive as vibration dampers to medical stents mainly
because of their high energy density and their ability to generate high actuating forces. One of the
potential applications of use of SMA is in robotics. SMA integrated composites provide a light-weight
solution for conventional grippers but have their fair share of disadvantages such as minimal movements
due to constrained degrees of freedom, less gripping force towards irregular structures, durability
reduction etc. In this work, SMAs are integrated into glass fiber reinforced fabrics with tailored
properties with the help of flat-knitting technology creating an Interactive Fiber Rubber Composite by
infiltrating the fabrics with liquid silicone. To determine the range of force induced, a simulation model
is developed to capture the transduced force of the composite when SMA is activated and the model is
calibrated with respect to a test set-up specifically tailored to determine the force exhibited. The results
obtained are utilized in a future study in determining the twisting behaviour of the composite, which
would further help in a better grip for small and irregular shaped objects.
