Abstract

Abstract: A composite material integral molding scheme based on the automatic fiber placement process was adopted for the inlet of aircraft. To ensure the feasibility of automatic fiber placement on the molded surface of the inlet, the interference problem between the inlet profile and the fiber laying head was studied. First, a interference detection computing program based on VC++6.0 was developed based on the meshed STL file of the inlet profile together with the boundary conditions of the wire laying head, and the position of the interference area on the molded surface was obtained and marked with large quantities of points. Then, the contour of the fiber laying head was modeled for the identified interference area with CATIA. Subsequently, the kinematic simulation of automatic fiber placement on the molded surface was carried out with VERICUT simulation software for verification purpose. Finally, the molded surface of the inlet identifying the interference area was fed back for design correction, and the right inlet profile satisfying the automatic placement was thus obtained.
