USA by Raytheon, following the success of its all composite turboprop, Starship. Called Premier 1, the business jet has an all RP fuselage with metal alloy wing. The carbon fiber/epoxy honeycomb fuselage is produced by computer-controlled automated machines, which are quicker than the hand lay-up used for the Starship. The cabin is reported to be 178 mm higher and 203 mm wider than competitors. The construction saves weight and is stronger than alnminnm. 

Chemical vapor infiltration (CVI) is a process whereby reactive chemical species are generated in the vapor phase and allowed to react with a solid substrate thus modifying its chemistry. A successful use of this process requires (1) an absolutely continuous and stoichiometric conversion of the initial to the final chemistry in the solid state, and (2) a continuous and eventually complete conversion of the morphology, density, surface tension, mechanical as well all other properties. Discontinuous or incomplete results cause a steep drop in strength, the premier measure of uniformity. By combining the complexities of chemical vapor deposition (this chapter) with those of fiber formation from a precursor fiber (Chapters 8 to 12), the process is therefore intrinsically more difficult to control than any other. 

Raytheon Aircraft have designed the Premier I cabin around a sandwich of inner and outer carbon fiber layers around a layer of honeycomb material. The carbon fiber/epoxy tows were applied by a Cincinnati Machine Viper 7-axis fiber placement system, producing a structure 20% lighter than an A1 one (Figure 23.19).
