The major goal of this research is to create a reliable model for predicting the mechanical properties of composite material with fatigue failure and to determine how changing the fiber orientation and the layer arrangement with regard to the applied loading direction affects the mechanical characteristics of the result components in order to establish the service life with health monitoring of these structures. A multilayer composite consisting of five layers which represent shell structure, with the middle layer reinforced by carbon fiber and the top and bottom layers reinforced by glassfiber random mate and unidirectional glassfiber. According to the tensile test results, the orientation (2 L- GF- (0°/90°)s) had the maximum tension load (13 kN) due to the asymmetrical arrangement of layers and identical distribution of the load within layers, whereas the orientation (2 L- GF-0°) had the lowest tension load (5.6 kN) compared with other fiber orientations. The compression strength of the orientation 4 (2 L- GF- (0°/90°)2) with (1.72 kN) and orientation 7 (2 L- (90°/ RGF)s with (1.7 kN) is greater than that of the other orientations. The specimen fails in the test at about (519318 cycles) with time (352 minute) for orientation number 3.
