Abstract: A gas turbine engine component includes a structural component having a surface, the structural component having an organic matrix composite material; and a cured thermal barrier layer on the surface, wherein the cured thermal barrier layer is a pre-ceramic layer including inorganic matrix containing silicon oxides reinforced with glass or quartz fibers.

Abstract: A composite airfoil is disclosed. The composite airfoil includes a first ply having a first plurality of strips of fiber oriented at a first angle with respect to a longitudinal axis and a second plurality of strips of fiber oriented at a second angle with respect to the longitudinal axis at least a first subset of the first plurality of strips of fibers have fibers intersecting and oriented at an angle to the fibers in at least a second subset of the second plurality of strips of fibers within a ply boundary.

Abstract: A gas turbine engine according to an exemplary aspect of the present disclosure includes, among other things, a fan case and a plurality of stator vanes integrally formed with the fan case. A method is also disclosed.

Abstract: A fiber composite material comprises a polymer matrix, carbon fibers, and non-carbon fibers, wherein the non-carbon fibers have a strain to failure value greater than the strain to failure value of the carbon fibers. Also discussed is a preform comprising the fiber composite material combined in a three dimensionally woven structure. Also discussed is a fan blade for a jet engine.

Abstract: A bicycle assembly can include a main frame having a bottom bracket area to receive a bottom bracket. The bottom bracket area can be made of carbon fiber with one or more embedded seat blanks to serve as bearing surfaces within the bottom bracket area. The disks may be machined to a high tolerance to receive a bottom bracket.

Abstract: A bicycle assembly can include a main frame having a bottom bracket shell to receive a bottom bracket. The bottom bracket shell can be made of carbon fiber with one or more metal rings to serve as bearing surfaces within the bottom bracket shell. The metal rings may also be split metal rings with a gap between two spaced apart ends.

Abstract: A joiner panel system is formed from a composite material and includes a panel attached to a deck by a coaming or shoe and attached at its upper edge by a curtain plate that fits around obstructions at the ceiling area. The shoe can be readily installed to an uneven steel deck by stud welding to reduce installation time or attached to a composite material deck. A curtain plate fabrication method uses a laser scan or close range photogrammetry of the overhead area to optimize and automate the cutting of curtain plate sections. The curtain plate sections can then be readily installed in the overhead area. A composite material panel to provide good flame, smoke and toxicity properties and good mechanical properties is formed from a phenolic resin foam material, micro-balloons to reduce the weight and density, and reinforcing fibers and powder material to improve the mechanical properties. The panel can be formed by a method in which the core and face skins are co-cured to provide a good bond.
