The flexible sheet-like material comprises a textile layer, which is coated at least on one side with a functional layer which is permeable to gas but impermeable to the matrix material, acting as a barrier layer for the matrix material, and is produced by coating the textile layer directly with a foam or a paste.

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.

A vertical take-off and landing (VTOL) unmanned aerial vehicle (UAV) storage and launch system includes a UAV pod (108) having a UAV pod processor (114) and a UAV (102) selectively enclosed in the UAV pod (108), the UAV (102) having only two rotors (202).

According to one embodiment, a system for manufacturing a fully impregnated thermoplastic prepreg includes a mechanism for moving a fabric or mat and a drying mechanism that removes residual moisture from at least one surface of the fabric or mat. The system also includes a resin application mechanism that applies a reactive resin to the fabric or mat and a press mechanism that presses the coated fabric or mat to ensure that the resin fully saturates the fabric or mat. The system further includes a curing oven through which the coated fabric or mat is moved to polymerize the resin and thereby form a thermoplastic polymer so that upon exiting the oven, the fabric or mat is fully impregnated with the thermoplastic polymer. During at least a portion of the process, humidity in the vicinity of the coated fabric or mat is maintained at substantially zero.

A filter element including a filter media and methods for making the same are provided. The filter element includes a support core surrounded by a tubular ring of filter media. A first end of the tubular ring of filter media is coupled to a first end cap and a second end of the tubular ring of filter media coupled to a second end cap. The tubular ring of filter media includes a carrier media layer, a coarse filter media layer, a fine filtration media layer, a water-capturing media layer, and an outer wrap.

The present disclosure is directed to articles that include one or more coated fiber(s) (i.e., fiber(s) with a cured coating disposed thereon), where the coating includes a matrix of crosslinked polymers and optionally a colorant (e.g., pigment particles or dye or both). The cured coating is a product of crosslinking a coating composition including uncrosslinked polymers (e.g., a dispersion of uncrosslinked polymers in a carrier, wherein the uncrosslinked polymers are crosslinked to form the matrix of crosslinked polymers). The present disclosure is also directed to articles including the coated fibers, methods of forming the coated fibers and articles, and methods of making articles including the coated fibers.

The filament and suture products disclosed are to be implanted in the body, having non re sorbable ingredients with absorbent qualities to disperse an antibiotic and strong enough to hold tissue securely but flexible enough to be printed or knotted. The products are biocompatible and consist of two dissimilar polymers having unmelted cellulose fiber. These dissimilar polymers and the unmelted fibers are densified by compression and the removal of moisture having fiber orientation and alignment, showing low levels of radiopacity. These products will have radiopacity in household units (HU) ranging from −200 to 200 HU and produce meshes, bone grafts, scaffolds or wound care products where bone bridging can be observed.
