accurate correlation between the craze density and the optomechanical properties of fiber

What is it about?

A modified method was suggested to improve the performance of the Pluta microscope in its nonduplicated mode in the calculation of the areal craze density especially, for relatively low draw ratio (low areal craze density). This method decreases the error that is resulted from the similarity between the formed crazes and the dark fringes of the interference pattern. Furthermore, an accurate method to calculate the birefringence and the orientation function of the drawn fibers via nonduplicated Pluta polarizing interference microscope for high areal craze density (high draw ratio) was suggested. The advantage of the suggested method is to relate the optomechanical properties of the tested fiber with the areal craze density, for the same region of the fiber material.

Why is it important?

Understanding the crazing phenomenon can help us in suggesting methods for controlling the fracture process in polymers, which enables us to improve the mechanical properties of polymers during the manufacturing process
