Because of high temperature above 1000°C on fire, and Oxidation of carbon fiber at high temperature, fireproofing measure should be make to take advantage of the inorganic adhesive for beams strengthened by carbon fiber sheet bonded with the adhesive. The problem of which fireproofing material should be choose and how to make fireproofing measure needs to resolve. Fireproofing test is make for beams strengthened by carbon fiber sheet bonded with the adhesive protected by Thick-typed Fireproof Coating for steel structure (TFCSS) and Thick-typed Fireproof Coating for tunnel (TFCT). Typical damage state of the two typical coating is compared on and after fire, Temperature field of specimen is analyzed, and fireproofing effect is compared. The test results indicate that, under the protection of fireproof coating with proper structure, TFCT and TFCSS can supply effective fireproofing protection for carbon fiber sheet, but the former is inferior to the latter because the latter is easier to drop and crack in fire

Because of high temperature above 1000°C on fire, and Oxidation of carbon fiber at high temperature, fireproofing measure should be make to take advantage of inorganic adhesive for slabs strengthened by carbon fiber sheet bonded with the adhesive. The problem of which fireproofing material should be choose and how to make fireproofing measure needs to resolve. Fireproofing test is make for slabs strengthened by carbon fiber sheet bonded with the adhesive protected by Thick-typed Fireproof Coating for steel structure (TFCSS) and Thick-typed Fireproof Coating for tunnel (TFCT). Typical damage state of the two typical coating is compared during and after fire, Temperature field of slab specimen is analyzed, and fireproofing effect is compared. The test results indicate that, steel wire mesh in the middle of coating layer can prevent coating from falling fully, so steel wire mesh is necessary for fireproofing coat which is not too thick. under the protection of fireproof coating with proper construction, TFCT and TFCSS can supply effective fireproofing protection for carbon fiber sheet, but the former is inferior to the latter because the latter is easier to drop and crack in fire. So, TFCT with steel wire mesh can supply the most effective protection for slabs strengthened by carbon fiber sheet bonded with the adhesive.

The developments of electromagnetic wave shielding materials are strongly required because the malfunction of electronic equipment, mobile phone and wireless LAN avoids. In this study, it was investigated that the electromagnetic shielding effectiveness of carbon fiber sheets were enhanced by the ferrite which was coated by the microwave hydrothermal process. For coated carbon fiber sheet, the effects of ferrite and lamination of carbon fiber textile on the electromagnetic wave shielding effectiveness were discussed. In the range of frequency (100 – 1 GHz), the electromagnetic wave shielding effectiveness was measured by using TEM-Cell. The electromagnetic wave shielding effectiveness was greater for the coated carbon fiber sheets than for the uncoated carbon fiber sheets. When the insulation film was located between two carbon fiber sheets, the electromagnetic wave shielding effectiveness increased.
