چکیده

In this paper the tension-tension fatigue behavior (R=0.1) of fiber reinforced polymer composites made by hand lay up and vacuum infusion process (VIP) were studied. According to the results of static tension test, tensile strength was higher in the VIP specimens than that of the hand lay up specimens, 387 MPa and 233 MPa respectively. At 76MPa stress amplitude, the VIP specimens survived for 151624 cycles; whereas the fatigue life of hand lay-up specimens was 44422 cycles at 65.57 MPa stress amplitude. Longer life of the VIP specimens can be related to the higher number of defects formed during manufacturing of the hand lay up specimens. Examining the fracture surfaces of the specimens after fatigue tests, revealed that fiber pull out and debonding in hand lay up specimens and matrix cracking and debonding in the VIP specimens were the main mechanisms for their fatigue failures.
