Abstract
A fiber-reinforced polymer alloy substrate, in which continuous reinforcing fibers are arranged in parallel and are impregnated with a polymer alloy, is characterized in that: a polymer alloy obtained by combining thermoplastic resins of at least two types is used as the polymer alloy; the fiber volume content is in the range of 40 to 70% by volume; and the dispersion parameter D of the fibers is 90% or more. In the obtained fiber-reinforced polymer alloy substrate, the reinforcing fibers are dispersed with high uniformity, and high mechanical properties and heat resistance are stably exhibited with low variation.
