Özet
Fracture toughness of chopped strand glass fiber reinforced particle-filled polymer composite beams was investigated in Mode I and Mode III loading conditions using three-point bend tests. Effects of crack angles on fracture behavior were also studied. The specimens, which have inclined crack at an angle theta to the axis of the specimens, were used to carry out the tests. The specimens were tested with inclination angles 30degrees, 45degrees, 60degrees and 75degrees. The results are compared with the values of K-IC obtained using conventional (theta=90degrees) specimens. In addition, J integrals were also determined. J(IC) increases continuously with increasing in crack angle from theta-30degrees to theta=90degrees. In contrast, J(IIIc) decreases with the crack inclination angle theta from 30degrees to 90degrees.
