Study on Optimization of Drilling Parameters for Laminated Composite Materials

Abstract

Fiber-reinforced resin matrix composites have been widely used in aerospace, construction, transportation and other industries due to their excellent mechanical properties and flexible structural design. However, due to the influence of the molding process, the composites are easily delaminated, which greatly reduces the structural stiffness of the components. This is a common problem in the processing of fiber-reinforced composite components. In this paper, through the combination of finite element simulation analysis and experimental research, drilling parameter analysis was carried out for prefabricated laminated composites, and the influence of different processing parameters on the processing axial force was qualitatively compared. The inhibition rule of variable parameter drilling on the damage propagation of initial laminated drilling was explored, which further improves the drilling connection quality of composite panels with laminated materials.

Effect of Drilling Parameters and Tool Geometry on the Thrust Force and Surface Roughness of Aerospace Grade Laminate Composites

“…They put forth that fuzzy logic was a useful instrument for this goal and smaller delamination factor values could be achieved with medium cutting force levels. Yu et al [ 27 ] explored effects of cutting parameters like cutting and advance speed to optimize the drilling of fiber-reinforced resin laminates. The investigation team underlined that simulation-assisted finite element analyses were able to be utilized together with experimental efforts and an increase in the dynamic advance speed would set off an apparent axial cutting force change.…”
