Abstract: A smart roller comprises: an exterior annular cylinder portion comprising an elastomeric material and having an exterior cylindrical surface; a sensor array imbedded in a volume of the exterior annular cylinder portion, the sensor array extending in an axial direction and in a circumferential direction of the exterior annular cylinder portion, the array comprising a plurality of independently sampleable sensor elements, each sensor element located for measurement at a corresponding axial and circumferential sensor location; a rigid interior portion, at least a portion of the rigid interior section disposed in a bore of the exterior annular cylinder portion, the rigid interior portion connected to the exterior annular cylinder portion for unitary rotational movement therewith; and readout electronics operably connected to the sensor array and configurable to independently sample sensor output from each of the sensor elements.

Abstract: Porosity causing gas-based defects are detected, located, identified, and/or characterized by the use of defect information generated from gas flow data corresponding to gas flow characteristics measured by one or more sensors on a composite part processing piece such as a mould or membrane used during a composite manufacturing process. The defect information is generated using techniques including one or more of profiling the gas flow data, fingerprinting, line leak detection, analytical triangulation.

Abstract: A system is provided for collecting data during vacuum molding of a composite part using a mold including an air tight, flexible membrane sealed to a tool. The system comprises a plurality of MEMS sensors coupled with the interior of the mold at different locations over the part. Each of the sensors produces signals related to a process parameter, such as pressure within the bag, that is sensed at the location of the sensor.

Abstract: A system collects data relating to a process performed within an autoclave, and wirelessly transmits the data to a receiver located outside the autoclave for processing. One or more sensors inside the autoclave sense process parameters such as temperature or pressure. The transmitter is housed in a protective container that protects the transmitter against the effects of autoclave heat and pressure.

Abstract: Method and apparatus for treating ultrahigh molecular weight, high strength polyolefin to improve its adhesive bonding to a resin such as epoxy, vinyl ester, polyester, polyurethane, polyolefin or thermoplastic rubber are provided. The method includes the steps of soaking the polyolefin in a first solution comprising (i) an aromatic ketone photosensitizer, and (ii) a first solvent selected from the group consisting of a benzene derivative, an alkyl halide, and a cyclic alkane; removing any excess first solvent; coating the surface of the polyolefin with a second solution comprising (i) about 15 to 70 weight percent of a monomer independently selected from the aforementioned group, (ii) about 0.25 to 5 weight percent of an aromatic ketone photosensitizer, and (iii) about 25 to 84.
