Abstract: A rig for testing mode II fatigue of a composite component. The rig includes a clamp for clamping one end of the component. A first contact arrangement is provided for contacting one side of the component and a second contact arrangement is provided for contacting an opposing side of the component, the first and second contact arrangements being spaced from the clamp. A loading fork is provided for applying load to the component. The loading fork includes a first and a second portion arranged such that in use, when the loading fork is loading the component in one direction the first portion contacts the first contact arrangement and the second portion is spaced from the second contact arrangement, and when the loading fork is loading the component in an opposite direction the first portion is spaced from the first contact arrangement and the second portion contacts the second contact arrangement.
