摘要： A modular sensor (10) for damage detection with an optical fiber (FBG sensor (4)) to detect a damage of a composite material (100), having a high level of visibility and manageability, and its manufacturing method is described. A structural composite material (100) embedded with this modular sensor (10) for damage detection is also described. The modular sensor (10) comprises an optical fiber including a FBG sensor (4), a connector (12) connected to an end portion of the optical fiber, and a tube and/or a film partly covering the optical fiber at a portion where the fiber is drawn out of the composite material (100) in order to prevent breakage of the optical fiber due to stress concentrated at said portion.

摘要： In an example, a method for forming a composite part includes, based on a part specification, cutting layers (110) of material in a sequence and positioning the layers to form a stack (112). For each layer, after positioning the layer and before cutting a next layer in the sequence, the method includes (i) scanning along a length of the layer to determine an image, (ii) determining, based on the image, at least two edges (116) of the layer (110), (iii) determining, based on the edges, a measured width at locations along the length of the layer, (iv) comparing the measured width at each location to a target width at the location, (v) deciding, based on the comparison, whether to adjust the production process, and (vi) if the decision is to adjust the production process, then adjusting the production process based on the comparison. The part specification specifies the target width at each location.

摘要： A system (50) and method for internally inspecting a tubular composite part (10) so as to identify and measure adhesive flow therewithin are provided, along with an endpoint adapter (30) assembly of a near infrared (NIR) spectrometer (54). The system (50) includes an end point adapter that fits within and maintains a consistent cross-sectional position within the tubular composite part (10). The system (50) also includes a plurality of optical fibers (40) extending radially outward from the end point adapter. The end point adapter moves longitudinally through the tubular composite part (10) and receives light with the plurality of optical fibers (40) following interaction of the light with the tubular composite part (10). The system (50) further includes a NIR imaging spectrometer (54) configured to disperse the light being collected by the plurality of optical fibers (40) across an NIR spectrum λ and a NIR camera (58) configured to generate images of the tubular composite part (10) based on dispersed light.

摘要： The present invention concerns an apparatus and method for testing materials. More particularly, but not exclusively, this invention concerns an apparatus and method for testing materials which have a useable shelf-life. The invention also concerns an apparatus and method for testing materials which have a useable shelf-life dependent on the chemical degradation of the material. The invention provides a method of obtaining an indication of the lifespan of a chemically reactive material. The method comprises taking an infrared (IR) spectroscopic measurement (26) of the material. The measurement results are compared (28) to a database of previously obtained measurement results. Depending on the comparison (28) of the measurement result to the database of previously obtained measurement results, an indication (30) of a measure of the lifespan of the chemically reactive material is determined and provided. An infrared spectrometer (32) and a method of calibrating an infrared spectrometer is also provided.

摘要： According to the invention, the fibre direction of a carbon-fibre material of an object which is to be tested is detected using the polarisation direction of light reflected by the object which is to be tested. If unpolarised light, for example, is incident on carbon-fibre, the light reflected by the fibres is polarised in the fibre direction.

摘要： Die vorliegende Erfindung betrifft ein Verfahren zur zerstörungsfreien Prüfung der Dichte und Homogenität von transluzenten Bauteilen. Bei dem Verfahren wird durch zweidimensionale Abtastung des Bauteils (3) mit einem Laserstrahl (2) ein ortsaufgelöstes Transmissionsbild (5) aufgezeichnet. Das Transmissionsbild (5) wird anschließend mit geometrischen Daten des Bauteils (3) korrigiert, um von einem Dickenprofil des Bauteils (3) unabhängige Transmissionsdaten zu erhalten. Aus den Transmissionsdaten lassen sich Homogenitäts- und Dichtevariationen des Bauteils (3) in dem abgetasteten Bereich unmittelbar erkennen. Das Verfahren eignet sich vor allem für die schnelle und kostengünstige zerstörungsfreie Prüfung von Bauteilen aus expandierten Kunststoffen und ermöglicht eine Qualitätskontrolle dieser Bauteile während der Fertigung.

摘要： A polymer composite material (10, 110, 210, 310) is described. The material includes a settable matrix material (12), a plurality of reinforcement members (14) and a plurality of capsule members (16). Each capsule member (16) includes a shell layer (22) encapsulating an indicator material (24). The polymer composite material comprises an initial condition in which each shell layer contains the indicator material, and a damaged condition in which at least one shell layer is ruptured, releasing indicator material. The polymer composite material is changed from the initial condition to the damaged condition by the application of a predetermined force to the polymer composite material.
