A phenol resin-impregnated sheet formed by impregnating a porous resin sheet with a phenol resin having a degree of cure of from 70% to 95% is arranged on and lamininated to the surface of a carbon fiber-reinforced thermosetting resin sheet. The thickness of the phenol resin impregnated sheet is between 0.01 mm and 1.0 mm. A very even, strong and water-proof wood reinforcing material is obtained. The wood reinforcing material is intergrated and cured on the surface of the wood material by the phenol resin-impregnated sheet to reinforce wood material (single board or bonded board) to form a reinforced wood material. The wood reinforcing material adheres suitably with the wood material and does not cause environmental contamination.

Reinforcing material for wood and reinforced wood

Carbon fiber prepeg for wood reinforcement, wooden sheet laminated therewith, wood reinforcing composite comprising carbon fibers and the wooden sheet, and carbon fiber reinforced wood

An electromagnetic wave shielding material comprises a composite carbon-resin compound obtained by reacting to proceed polymerization of a resin forming material with carbon powder intermixed therewith. The resulting compound has carbon powder substantially uniformly dispersed in the resin and exhibit superior electromagnetic wave shielding effect, in addition to good fire resistance. The resin may be phenol, melamine, furan or the like, and the carbon powder is preferred to be incorporated at a content of not less than 40% of the total weight.
