Study of the fracture facies when drilling c-orthocryl carbon-resin composite material for orthopedic prosthesis

The objective of this study is to determine the different micro damages caused to the socket of an orthopedic prosthesis, during its drilling before and after static tensile test, in order to estimate the ultimate microscopic damage when drilling. For this, carbon-c-orthocryl composite material specimens were produced by infusion moulding, a mechanical test is carried static traction and charpy impact, to determine their mechanical performance. To quantify and compare the different damages caused by machining, SEM microscopy was carried out through deferent surfaces. The results Visualize that the material has undergone all the known Degradations including resin breakage, intralaminar, translaminar, and interlaminar delamination, decohesion, and fiber ruptures are consistent with those referenced in the bibliography., All these degradations were identified and quantified to determine their origins. Poor wetting between the fibers and the resin was identified, to address this, it was recommended to review the moulding technique by increasing the amount of retarder. Furthermore, the contribution of this study yield essential insights into the structural laminate and the resin composition, providing a pathway for enhancing carbon-c-orthocryl socket machinability to drilling
