Description
Summary:Aiming at the phenomenon of delamination and serious tool wear when processing carbon-carbon composite materials by traditional mechanical tools, an abrasive water jet reaming process for carbon-carbon composites is proposed. First, the carbon-carbon composite material is prepunched by a certain method, and then the abrasive water jet is used for cutting and reaming. The internal stresses and interlayer displacements of the carbon-carbon composite material during the direct impact and cutting simulation of the abrasive water jet are compared and analyzed. The result found showed that the abrasive water jet reaming process can effectively reduce the stress on the carbon-carbon composite during the hole processing, thus greatly reducing the occurrence of delamination of carbon-carbon composites and improving the quality of the composite. For calculations, a finite-element model of the abrasive water jet processing carbon-carbon composites was established using the ANSYS/LS-Dyna18.0 software. Experiments were carried out, and they confirmed the correctness of the finite-element model employed.
