摘要： An aircraft transparency includes a first ply having a first major surface and a second major surface. A second ply is spaced from the first ply and has a third major surface and a fourth major surface. A polymeric interlayer is located between the first and second plies. At least one bore extends through the first and second plies and the interlayer. A high strength bushing is located in the bore, with an outer sidewall of the bushing in direct contact with the material of the first and second plies. In one embodiment, the bore is a tapered bore and the bushing has a tapered outer sidewall. In another embodiment, the bore is a cylindrical bore and the bushing has a cylindrical outer sidewall.
