Title:
PRODUCTION OF A RADIO WAVE ABSORBING STICK AND RADIO WAVE ABSORBER
Document Type and Number:
Japanese Patent JP3736668
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To efficiency mass-produce a radio wave absorber with excellent waterproofness only by simply fixing radio wave absorbing sticks to a frame body by continuously producing the radio wave absorbing stick through drawing molding.
SOLUTION: A glass fiber bundle as an aligned inorganic fiber bundle 1 is continuously supplied and the glass fiber bundle is impregnated with a vinyl ester resin as a thermosetting resin 2. Besides, as a radio wave absorbing member 3, paper of width 8 mm composed of carbon fiber of a specified resistance is continuously supplied. The glass fiber bundle 1 impregnated with the resin 2 is abutted to a roll, opened and led into a metallic mold 4, and paper is led into the metallic mold 4 (heated to 100 to 150°C) so as to be positioned at the center of the glass fiber bundle 1 and drawn by a suitable drawing means 8 so that a radio wave absorbing stick 5 having a rectangular cross section can be provided. The radio wave absorbing stick 5 is cut at every length of 4 m by a cutting member 9. In this case, a suitable waterproofing means is applied to an end face of the radio wave absorbing stick 5.
