A carbon fiber washer is provided and includes a carbon fiber fabric made of a plurality of fiber bundles being woven, in which each of the plurality of fiber bundles is made of discontinuous fibers; the advantage of the carbon fiber washer of the present invention includes high temperature and fatigue resisting, and weather proofing. The structure of the carbon fiber washer is stable due to the use of discontinuous fibers; breakages of discontinuous fibers do not affect other unbroken discontinuous fibers, so that the structure of the carbon fiber washer would not be loosened or delaminated and the service life can be prolonged accordingly.

One example provides a composite. The composites includes a core layer comprising a thermoplastic polymer and having a first and a second sides opposite to each other; a first set of two layers disposed over at least a portion of the core layer respectively on the first and the second sides, each layer of the first set including carbon fibers aligned in a first direction in a plane; and a second set of two layers disposed over at least a portion of the first set of two layers respectively on the first and the second sides, each layer of the second set including carbon fibers aligned in a second direction perpendicular to the first direction in the plane In the plane, the composite has a length and a width, the length larger than the width and parallel to the second direction.

Described herein are molecular inks, methods for printing the molecular inks on flexible substrates, and methods for forming printed electronic elements, such as resistive heaters, force sensors, motion sensors, and devices that include these elements, such as force responsive conductive heaters. The methods include printing a molecular ink on a flexible substrate that is heated to 30° C. to 90° C. before and/or during the printing process and curing the substrate to produce a conductive pattern thereon. The molecular inks generally include a particle-fee metal-complex composition formulated from at least one metal complex and a solvent, and optionally, a conductive filler material, and/or surfactant.

Various embodiments directed towards methods of applying sizing to fibers are disclosed herein. In some embodiments, solvent can be used to dissolve a sizing material into a solution, which can then be used to coat the fibers. In some embodiments, a water bath is used to coagulate a sizing on the fiber surface and to remove the remove solvent after coating the fibers, so that water vapor can be created during a subsequent drying step as opposed to solvent vapors. In some embodiments, strong acids or strong bases can be used as the solvent.
