Abstract:
A hybrid carbon fiber spun yarn having a core region with carbon fibers as a main component, and a surrounding region with carbon fibers as a main component and covers an outer peripheral surface of the core region. 20% by mass or more of fibers forming the core region are long carbon fibers having a fiber length of 500 mm or longer. 80% by mass or more of fibers forming the surrounding region are short carbon fibers having a fiber length of less than 500 mm. A mass ratio between the long carbon fibers and the short carbon fibers (long carbon fibers:short carbon fibers) is in a range of 20:80 to 80:20.
