Disclosed are a method and a device for preparing a single-crystal cladding. The method may include preparing an amorphous material; melting the amorphous material to form an amorphous melt; submerging an optical fiber in the amorphous melt; forming an amorphous cladding around a periphery of the optical fiber; and obtaining the single-crystal cladding by performing a crystallization process on the amorphous cladding. The device may include an amorphous material preparation component configured to prepare an amorphous material; an amorphous cladding preparation component configured to melt the amorphous material to form an amorphous melt, submerge an optical fiber in the amorphous melt, and form an amorphous cladding around a periphery of the optical fiber based on the amorphous melt and the optical fiber; and a single-crystal cladding preparation assembly configured to perform a crystallization process on the amorphous cladding to obtain a single-crystal cladding.

The method includes the steps of functionalizing a polyaryletherketone (PAEK) polymer, and blending the PAEK polymer with water to form a sizing composition. The method may further include the step of applying the sizing composition to a fiber. The method may further include the step of heating the fibers, coated with sizing composition, for example to between 300C-400C. In some methods, the functionalized PAEK polymer comprises functionalized polyetherketoneketone (PEKK). In yet other methods, the functionalized PAEK polymer comprises sulfonated PEKK (sPEKK).

A method and an apparatus for producing a reinforcement mesh. Here, a reinforcement fiber strand is firstly saturated with a resin (H) and cured to form a cured, fiber-reinforced strand material. The strand material present as an endless material is then cut lengthwise into bars, which are then used as longitudinal bars or transverse bars for forming the reinforcement mesh. A connecting material is used at each intersection point between a longitudinal bar and a transverse bar and is dispensed in liquid form at the intersection point or is liquefied and then cured at the intersection point. A fixed connection is thus created between the longitudinal bars and the transverse bars at the intersection points. Between the intersection points, the longitudinal bars and the transverse bars have portions that are free of connecting material.

The present invention provides an electromagnetic shielding metal-coated glass fiber filler to be used as a composite with resin, the glass fiber filler including: glass fiber; and a metal coating in the longitudinal direction of the glass fiber, wherein the metal coating is made of an alloy containing a first metal consisting of zinc and a second metal consisting of a metal having a lower oxidation-reduction potential than zinc (i.e., being more easily oxidized than zinc), the second metal is at least one selected from the group consisting of barium, strontium, calcium, magnesium, beryllium, aluminum, titanium, zirconium, manganese, and tantalum, and the alloy contains the first metal in an amount of 50% by mass or more.
