  • Patent number: 10807313
    Abstract: A profile body of a not liquefiable material is used as a connecting element between a first object and a second object. The profile body may especially be metallic and/or may be bendable. The profile body, in contrast to a conventional wire, however, has a shape defining a first and a second undercut. The method includes embedding the profile body in the second object so that the second undercut is within material of the second object, and embedding the profile body within material of the first object so that the first undercut is within the first object, and wherein at least embedding of the profile body in the first object is caused by mechanical energy impinging on the first object and/or on the second object while the first object and the second object are pressed against each other.

  • Patent number: 10800115
    Abstract: A method for designing fiber-composite parts in which part performance and manufacturing efficiency can be traded-off against one another to provide an “optimized” design for a desired use case. In some embodiments, the method involves generating an idealized fiber map, wherein the orientation of fibers throughout the prospective part align with the anticipated load conditions throughout the part, and then modifying the idealized fiber map by various fabrication constraints to generate a process-compensated preform map.

  • Patent number: 10794834
    Abstract: A technique for automated online inspection of manufacture of a fibre reinforced polymer composite part during automated ribbon placement (e.g. ATL or AFP) uses interferometric inspection (e.g. OCT) to detect deviations from a planned lay-up for the part, to identify defects. On line, real-time inspection (i.e. on-the-fly) is demonstrated, and edge type defects and whole surface defects are identifiable. A sensor is demonstrated that does not extend a working envelope of the robotic head used for rib bon placement.

  • Patent number: 10792872
    Abstract: A method for repairing a component constructed in multiple layers from a layer composite material comprises a step of removing material of the layer composite material of the component in the region of damage to the component in order to form a scarfed cutout, such that a scarfed peripheral contour formed from a plurality of layers of the component is formed. Furthermore, fiber-reinforced plastic strips, which exhibit a curable plastic material in an uncured state, are applied in layers in the cutout in order to create a replacement-structure semifinished product that is complementary to and butts against the scarfed peripheral contour of the component. In a further step, the curable plastic material contained in the fiber-reinforced plastic strips is cured in order to create a replacement structure and for joining the replacement structure to the component.

  • Patent number: 10775296
    Abstract: A device and method are provided for testing the effectiveness of an adhesive composition to adhere a sheet of material to a substrate. A connector is attached to the sheet and the adhesive is used to adhere the sheet to the substrate and permitted to cure to a selected amount. After (or even before, if desired) the adhesive cures, a load is applied to the connector, having the effect of pulling the sheet away from the substrate. The duration of the pulling and the amount of the load can be varied. If too large a dome is formed under the location of the connector, the adhesive does not pass the test. Optionally, the adhesive formulation is adjusted to make it stronger to resist such doming.

  • Patent number: 10744721
    Abstract: A first aspect of the invention provides a method of joining a part to a composite component, the composite component comprising fibres impregnated with a matrix material, and the part comprising a plurality of projections, the method comprising: inserting the projections into the composite component; and pre-heating the projections before they are inserted into the composite component, so that the projections are at a higher temperature than the composite component as they are inserted into the composite component. The projections locally heat the matrix material of the composite component as they are pushed into the composite component. Increased temperature during insertion is advantageous as the reduced matrix viscosity, due to the increased temperature of the matrix, results in better consolidation of the fibres around the projections and minimises the distortion of the fibres.

  • Patent number: 10746670
    Abstract: An inspection system for detecting defects in a workpiece can include an illumination source for illuminating a first section of the workpiece with a patterned light, wherein the illumination source does not illuminate a second section of the workpiece. The inspection system further includes a feedback camera for imaging the first section and producing a first output, and a background camera for imaging the second section and producing a second output. A processor compares the first output with the second output, and a controller alters the patterned light that is output by the illumination source based on the comparison. This feedback control continues until the background is suitably homogeneous or camouflaged compared to the defect, such that the visibility and/or detectability of the defect is increased.

  • Patent number: 10710143
    Abstract: A method for creating a termination by attaching some kind of fitting to the end of a tensile member such as a cable. The end fitting is provided with one or more internal cavities. Each cavity has a proximal portion that is adjacent to the area where the tensile member exits the fitting and a distal portion on its opposite end. A length of the tensile member's filaments is placed within this expanding cavity and infused with liquid potting compound. The method exploits the characteristic of a liquid potting compound as it transitions to a solid. During the solidification process tension is applied. The resulting linear displacement tends to pull the filaments residing in the potting compound into better alignment and improve load sharing.
