Shear Thickening Fluid (in plastic)

Click For Summary
SUMMARY

Shear thickening fluids (STFs) are being explored for their potential applications in enhancing the properties of Kevlar used in bulletproof vests. The discussion focuses on the possibility of incorporating STFs into molten plastic to create a material that exhibits rigidity under sudden force while remaining flexible under gradual stress. The inquiry emphasizes the need for further research on the interaction between STFs and plastics during the solidification process to determine if the desired properties can be achieved.

I have been looking into shear thickening fluids and how they are used with Kevlar for bullet proof vests. I am considering alternative uses but have limited knowledge on the subject. I would like to create a rigid solid that becomes harder and less flexible when a large force is suddenly applied but is more flexible and elastic when force is slowly applied. If the stf was added to molten plastic and then left to solidify would the plastic contain any of the properties of the stf?
