Web18 de mai. de 2024 · With advanced fiber steering techniques, it is possible to place fibers around hole openings. With this, the fibers are not cut and run continuously through the material. This usually results in an increased notched and bearing strength, as shown in [ 7, 8] for carbon/PA6. Webal1 presented a uni ed model for the open hole tension (OHT) and open hole compression (OHC) strength predictions using Enhanced Schapery Theory2 (EST). The EST model is used in the present study to deter-mine the damage and failure evolution in open hole compression and tension specimens made of IM7/8552 material.
