Investigation of Dry Sliding Wear Behavior of CFRP Composite Used in New Generation Aircraft Wings

Abstract

In this study, it is aimed to examine the effect of reinforcement laying angle on wear resistance of CFRP composites used in the automotive and aerospace industries. Experiments were carried out on Ball-On-Disc wear device under 1, 3 and 5 N loads at room temperature. 3D optical microscope was used to determine the volume losses in the samples. The worn surface morphology of the samples was examined with the help of SEM (Scanning Electron Microscopy). In the test results, the volume losses of the samples increased depending on the increasing loads and shear rate. It has been understood that the change of the laying angle is important in the dry-sliding resistance of the samples. The wear resistance of the samples produced with 45 degree laying was better at both sliding speeds and all loads. It has also been understood that the laying angle is also effective in the coefficient of friction. Delamination, plastic deformation type dominant wear mechanisms have occurred.
