A Technical Study of Hole Drilling in Ceramics/FRP Laminate Composite Components

Abstract:

Drilling process of the ceramic composite component (ceramics/FRP/aluminum alloy), as an example of similar ceramics/FRP laminate composite components, was studied intensively. According to the diverse machining properties of the composing materials of ceramic composite components, the special thinwall diamond core bit was developed, with copper based matrix of complex alloy and hot pressing process. Through machining competitive experiments, the feeding mode with constant pressure was determined. After analyzing the diverse hole defects, the process equipment with compressive pre stress was introduced to improve the hole drilling quality, with good validity proved theoretically by the finite element analysis and on this condition, water can be used as the coolant. The process technology presented in this paper can be used for hole drilling in similar composite components made of the same composing materials.
