摘要： A process for aligning discontinuous fibers, and composite products and mats comprised of highly aligned discontinuous fibers, including products of the process. Aligned discontinuous fiber composite products include a matrix of fibers, each fiber having a longitudinal fiber axis, the composite comprising a free, uncut edge extending along an edge axis. The longitudinal fiber axis of a majority of the fibers in the composite product are aligned within a predetermined alignment tolerance of an alignment axis non-parallel to the edge axis. Aligned discontinuous fiber mats may have a first areal density of fibers in a first region of the composite located inward relative to the free, uncut edge, and a second area density at or adjacent to the free, uncut edge.

摘要： Mesh susceptors for use in induction heating and bonding processes are tailored to obtain more uniform heating across the susceptor and hence, the bondline, when bonding composite parts. The susceptors are tailored by cutting and removing segments from the mesh areas where the induced current and hence, heat generation, is highest. An algorithm is employed to predict the induced current patterns throughout the mesh so that areas of high heat generation can be identified and then cut and removed. In this way, essentially uniform temperatures in metal mesh susceptors may be achieved by specifically designed cut patterns within the mesh even though the mesh susceptor is subject to non-uniform magnetic fields.

摘要： An apparatus and process for operating connectorless, free-space data porting optical structural composites with integrated optical or electrical busses are disclosed. Optical transceivers and fiber optic/coaxial cable are embedded into a foam-core composite sandwich structure which is infiltrated with vinyl ester resin. The embedded busses are composed of a signal source producing an optical free space signal, which is shone onto an optical/electrical bus containing a transceiver for converting this signal into another electrical or optical signal which then is imprinted upon a coaxial or fiber optic cable buried in the composite structure. The signal traverses the composite structure, then a transceiver converts the electrical/optical signal into a free space optical signal which shines out of the composite structure to an outside free space optical receiver. The optical free space signal is oriented to be received and transmitted at an angle of about 90 degrees relative to the composite material.
