Abstract: A method of analyzing computed tomography data according to an example embodiment of the present disclosure includes obtaining computed tomography (CT) data for a component, fitting an interpolant function to the CT data, and creating a mesh of a surface that extends through the component. The surface is arbitrary and non-planar. The method also includes querying the interpolant function at a plurality of points of the mesh to project the CT data onto the mesh, calculating a metric of the component based on the querying, and providing a notification of the metric. A system for computed tomography analysis is also disclosed. A method of analyzing computed tomography data for a component of a gas turbine engine that includes calculating a void area fraction is also disclosed.

Abstract: An airfoil wall that includes a wishbone-shaped fiber layup structure that has first and second arms that merge into a single leg. The leg includes fiber tows from each of the arms and the tows are interwoven in the leg. Each of the arms includes a first section that is distal from the leg and a second section that is proximal to the leg. The first section defines a first thickness and a first fiber tow count. The second section defines a second thickness that is greater than the first thickness and a second fiber tow count that is greater than the first fiber tow count. The single leg defines a third thickness that is greater than the second thickness and a third fiber tow count that is greater than the second fiber tow count.

Abstract: A method for determining coating thicknesses of a coated fiber embedded in a matrix is presented. A scanning electron microscope (SEM) image is captured of a composite material having multiple coated fibers embedded in a matrix. This image depicts a cross-sectional portion of the composite material. A processor identifies a region of the image depicting a cross-section of one among the plurality of coated fibers, and generates a line graph of a gradient of grayscale values as a function of a line scan. The line scan traverses across the image along a radius of the coated fiber, and extends between an interior location of the coated fiber and an exterior region outside the coated fiber. The processor identifies inflection points in the line graph of the gradient of grayscale values as a function of the line scan traverse location, and determines coating thickness based on these inflection points.
