摘要:
There is provided a random mat including carbon fibers and a matrix resin, wherein the carbon fibers in the random mat have an average fiber length in a range of 3 mm to 100 mm, a fiber areal weight of the carbon fibers is 25 to 10,000 g/m2, the carbon fibers include a specific carbon fiber bundles having a specific opening degree in a specific amount per the total carbon fibers, and the specific carbon fiber bundles with a thickness of 100 μm or more are included in a ratio of less than 3% of the number of the total specific carbon fiber bundles.
