Description
Summary:In this research, the main objectives of this investigation as, first, study the effect of fibers orientation on fatigue strength for composite materials, second, study the effect of fiber orientation on shape and direction of fracture surface for composite materials. The experimental work using to study fatigue limit for composite material with different fiber orientation as (00, 30o, 450, 60o, 90o) and study of the fatigue surface (shape and direction of fatigue surface of composite material) for each fiber orientation fiber. The material using for composite material in this research are epoxy resin matrix and glass reinforcement fiber with volume fracture of fiber in composite material about (0.21). The results are endurance fatigue strength with number of cycle for fiber orientation (00, 30o, 450, 60o, 90o) and the shape and direction of surface fatigue of composite material. في هذا البحث تمت دراسة تأثير، أولا : زاوية الألياف على مقاومة الكلل للمادة المركبة، ثانيا : دراسة تأثير زاوية الألياف على شكل الكسر الناتج و على اتجاه مساحة الكسر للمادة المركبة. تضمنت الدراسة العملية دراسة تأثير زاوية الألياف (0⁰، 30⁰، 45⁰، 60⁰، 90⁰) على إجهاد الكلل و شكل و اتجاه مساحة الكسر.
