A system includes a void filter that receives sensor data employed to produce or inspect a manufactured part, the void filter generates a void data subset indicating voids detected in the manufactured part. A stress analyzer processes the void data subset from the void filter and determines coordinate data and force data for the respective detected voids in the manufactured part. At least one deterministic model analyzes the coordinate data and the force data from the stress analyzer determined for the detected voids from the void data subset. The deterministic model analyzes failure of the detected voids with respect to time and generates deterministic output data indicating failure over a deterministic timeframe. A prognostic analyzer processes the deterministic output data from the at least one deterministic model and generates a failure prediction for the as manufactured part.

Automatic prognostic qualification of manufacturing products

One example includes a repair assembly that is comprised of a composite patch, an adhesive, and a veil. The adhesive is disposed between a composite structure that includes an anomaly to be repaired and the composite patch and the composite patch. The veil is disposed between the composite structure and the composite patch. The veil generates heat in response to electric power being applied to the veil, with the adhesive being cured with the heat generated with the veil to repair the composite structure including the anomaly.

Veil based composite structure repair

A process and device for 3D printing parts incorporating long-fiber reinforcements in an advanced composite material is disclosed. A nozzle for a 3D printing device receives a polymer material and a reinforcing fiber through separate inlets. A passage from the reinforcing fiber inlet cleaves the passage containing the polymer material, creating an interstitial cavity into which the reinforcing fiber is introduced. The polymer material closes back on itself and encapsulates the reinforcing fiber, then drags the fiber along with the flow and exits nozzle to be deposited on a work surface or part being manufactured.

Device and method for 3D printing with long-fiber reinforcement

An apparatus includes a first steel component having a first surface, a second steel component having a second surface, a corrosion resistant coating on at least one of the first and second surfaces, and an adhesive bonding the first and second components together. The corrosion resistant coating can be electrically conductive.
