Abstract: PURPOSE: Provided are hybrid fiber-reinforced composite comprising glass fibers and carbon fibers as glass-reinforced and carbon-reinforced composites, respectively for the radar absorbing structure. Accordingly, the resultant composite has moderate dielectric constant and prevents strength deterioration by containing carbon fibers instead of conventional carbon powder as conductive materials. CONSTITUTION: The hybrid fiber-reinforced composite has the characteristics of containing less than 10wt.% of carbon fibers based on the total weight of glass fibers and carbon fibers. The hybrid yarn-shaped composite materials are produced by gathering glass fibers and carbon fibers in an effective ratio, and the hybrid prepreg-shaped composite materials are produced by arranging carbon fibers and glass fibers in prepreg matrix such as polyethylene, polypropylene, polyamide, polyethylene terephthalate, etc.
