A reinforced composite panel and method of making the composite panel uses processed natural fibers such as bamboo along with a polymeric material. The method includes the steps of: treating a plant source comprising natural fibers with a solvent and processing the treated plant source. The processing step can include arranging the natural fibers into a sheet-like orientation in a variety of ways. A polymeric material is then applied to the natural fibers to form a composite sheet, and the composite panel can be formed from one or more composite sheets.

A recording medium is provided, such as paper, secured by magnetic microwires. The recording medium comprises: a pulp structure formed by pulp fibers, said pulp structure carrying microwires having a metal core of a predetermined material composition, and an insulating layer coating on said metal core; and at least one coating layer on at least one side of said pulp structure. The pulp structure is a single-layer structure with the microwires fully embedded in said single layer, the microwires having cross-sectional dimensions approximately equal to cross-sectional dimensions of the pulp fibers.

A method for continuously producing a mat of cellulose fibers intended for producing roofing elements made from bitumen-impregnated cellulose fibers, from a dilute slurry of cellulose fibers spread by a headbox on a dewatering fabric of a forming table having a predefined width, the dewatering fabric moving between an inlet of the forming table at the headbox side and an outlet of the forming table, moving the dilute slurry towards the outlet, gradually removing the liquids of the dilute through the dewatering fabric during the movement to obtain, at the outlet, the mat having a thickness of at least 2 mm, the dilute slurry having a certain level of pre-existing mineral materials. The method involves adding mineral material to the cellulose fibers by spraying a controlled quantity of aqueous solution or dispersion of mineral fillers over the width of the forming table onto the surface of the dilute slurry.
