摘要： Systems and methods for assessing strain in structural components are disclosed. Structural components may have geometric patterns of diffraction cavities within the structural component, with the diffraction cavities in the geometric pattern each having a cavity width and being spaced from each other by a cavity spacing distance. The method may include projecting beams of electromagnetic (EM) energy through the structural component to the geometric pattern of diffraction cavities to create diffracted beams of EM energy that are reflected from or transmitted through the geometric pattern of diffraction cavities and have diffracted wavelengths indicating changes in the cavity spacing distances due to strain caused when the structural component is exposed to environmental conditions, detecting the diffracted wavelength of the diffracted beams, and correlating the diffracted wavelengths of the diffracted beams to the strain in the structural components.

摘要： An installation assembly and an associated method for forming a bonded join are provided to permit the adhesive attachment of a first workpiece, such as a patch, to a portion of a second workpiece. The installation assembly and the associated method provide for at least partial debulking of the adhesive prior to curing of the adhesive such that the resulting bondline may have improved mechanical properties as a result of having fewer voids and/or porosity. The installation assembly may include an installation stand and a carrier plate supported by the installation stand and including an attachment surface configured to carry the first workpiece. The installation stand also includes an adjustment mechanism for positioning a carrier plate to a first predefined position to define a gap between the first and second workpieces and also to a second predefined position such that a predetermined bondline thickness is defined between the first and second workpieces.

摘要： A composite laminate patch for reworking an inconsistent area in a structure has inner and outer control regions possessing differing interlaminar fracture toughnesses for controlling the advance of a disbond in the patch. One or more separation zones in the patch between the control regions aids in diffusing the fracture energy of the disbond as the disbond advances from the inner region to the outer region.

摘要： Non-destructive testing apparatuses, systems, and methods for assessing strain in structural components are disclosed. Structural components include induced predetermined regions having materials of varying density, including induced geometric patterns of differing densities within the structural component that can be a composite material structural component. The method includes projecting waves of energy, that can be beams of electromagnetic (EM) energy and/or waves of ultrasonic (UT) energy, into or through the structural component to evaluate the predetermined induced pattern region of varying density and determining existing strain within a structural component based on the detected energy response.

摘要： Systems and methods for assessing strain in structural components are disclosed. Structural component may have geometric patterns of grooves, with the grooves in the geometric pattern each having a groove width. The method may include illuminating the geometric pattern of grooves with a first light at a first wavelength that corresponds to the groove width to create diffraction when the first light hits the geometric pattern of grooves and corresponding changes in the wavelength of the light reflected from the geometric pattern of grooves indicating changes in the groove widths due to strain caused when the structural component is exposed to environmental conditions, detecting the wavelength of the light reflected from the geometric pattern of grooves, and correlating the detected wavelength of the light reflected from the geometric pattern of grooves to the strain in the structural components.
