    Abstract: There is provided a quantitative method for determining a level of a sanding surface preparation of a carbon fiber composite surface, prior to the carbon fiber composite surface undergoing a post-processing operation. The quantitative method includes fabricating a ladder panel of levels of sanding correlating to an amount of sanding of sanding surface preparation standards for a reference carbon fiber composite surface of reference carbon fiber composite structure(s); using surface analysis tools to create target values for quantifying the levels of sanding; measuring, with the surface analysis tools, sanding surface preparation location(s) on the carbon fiber composite surface of a test carbon fiber composite structure, to obtain test result measurement(s); comparing the test result measurement(s) to the levels, to obtain test result level(s); determining if the test result level(s) meet the target values; and determining whether the carbon fiber composite surface is acceptable to proceed with the post-processing operation.

    Abstract: There is provided a method for determining a quality of an abrasive surface preparation of a composite surface, prior to the composite surface undergoing a post-processing operation. The method includes fabricating a plurality of levels of abrasive surface preparation standards for a reference composite surface; using one or more surface analysis tools to create target values for quantifying each of the levels; and measuring, with the surface analysis tools, one or more abrasive surface preparation locations on the composite surface of a test composite structure, to obtain one or more test result measurements. The method further includes comparing each of the one or more test result measurements to the levels, to obtain one or more test result levels; determining if the one or more test result levels meet the one or more target values; and determining whether the composite surface is acceptable to proceed with the post-processing operation.

    Abstract: Provided are molds, comprising non-metal base portions and protective optical layers that cover and shield these base portions from laser ablation. For example, a protective optical layer may reflect a laser beam used for ablating the mold. Methods of forming these protective optical layers on non-metal base portions are also provided. In some embodiments, this protective optical layer is the outermost layer exposed to the environment. Alternatively, the protective optical layer may be covered by a release layer. The release layer may be retained or removed during laser ablation. In some embodiments, light emitted by a mold during laser ablation is analyzed to determine performance of its protective optical layer. This feedback may be used to control the laser ablation such as to control orientation of the laser beam relative to the mold.
