Abstract:
The axial stress intensities resulting from the repeating element model stress analyses demonstrate that the severely misaligned layer planes can have a significant effect on fiber tensile strengths. Stress intensities increase with increasing relative misalignment angles and decreasing spacing between misaligned regions. Results also indicate the misalignment angle below which this effect becomes insignificant. For the fiber studied here, relative misalignment angles of approximately 6 ° result in stress intensities of only 10% above the applied tensile stress.
