Disclosed is a process of manufacturing a thickened angle ring. The process includes the steps of: soaking wet paper into deionized water for 1 hour; beating bonding surfaces of the two pieces of wet paper into fuzzed and rough surfaces; placing a heat resisting polyester film and a nylon net on a mold, and placing one fuzzed wet paper on the mold in contact with the nylon net on smooth side thereof; placing the other wet paper in contact with the fuzzed surface of the previous wet paper on fuzzed side thereof, and beating until the wet paper fits the mold; placing a further heat resisting polyester film and a further nylon net on the two pieces of wet paper for pressing.

A method for coating an article using a wax solution for providing strength to its structure while formulating the wax so it is biodegradable and compostable after the article is spent. The method using an annealing process of rapidly cooling the wax to increase its strength to a desired hardness.

Example approaches are disclosed for manufacturing composite or fiber reinforcement preforms. Liquid, fibrous, binding and potentially other materials are mixed into a composite mixture slurry in a slurry container. A porous tool having a specific porous outer surface portion approximating a specific exterior surface portion of a spatial shape of a final product is immersed in the slurry container. A suction pressure is applied to draw a portion of the fibrous material intermixed with a corresponding portion of the binding material in the slurry onto the specific outer surface portion. The porous tool attached with the wet preform is removed from the slurry container. The wet preform is partially dried into a partially dried preform attached to the porous tool. The partially dried preform is dried, solidified and/or consolidated and/or injected with a resin and cured into a solid composite preform of the spatial shape of the final product.
