Abstract: The present invention relates to a multifunctional wood preservative composition containing a compound prepared by reaction of hydrazine hydrate and boric acid and to a method for wood preservation treatment using the same.
The wood preservative composition of the present invention can not only impart flame retardant, insect-repellent, rot-resistant, insect-repellent, and rust-proof effects to wood, such as various wooden structures including wooden cultural assets, but also causes no whitening and makes relatively fewer color changes for dancheong. Furthermore, the wood preservative composition of the present invention is provided as a one-component type liquid and thus can save time and costs for wood treatment and is convenient to use.

Abstract: A method for manufacturing carbon fiber reinforced aluminum composites is provided. Particularly, the method uses a stir casting process during a melting and casting process and reduces a contact angle of carbon against aluminum by inputting carbon fibers while supplying a current to liquid aluminum to induce the carbon fibers to be spontaneously and uniformly distributed in the liquid aluminum and inhibits a formation of an aluminum carbide (Al4C3) phase on an interface between the aluminum and the carbon fiber, thereby manufacturing carbon fiber reinforced aluminum composites having excellent electrical, thermal and mechanical characteristics.
