Description
Summary:A preliminary study has been made of the tensile and fatigue fracture morphology of acrylic fibers. Tensile breaks show a characteristic granular fracture surface which suggests the separate failure of fibrillar units in the fiber structure. In some instances, there are separate crack and final failure regions; in others, the fracture is in transverse steps linked by axial splits. The main characteristic in tensile fatigue is axial splitting of the fibers. The loading conditions for fatigue failure are less severe than in steady loading there is no zero minimum load criterion for fatigue failure as found in some other fibers.
