PURPOSE:To improve interlaminar shearing strength and conductivity in the direction of a thickness of a molded body by preventing cracks among single yarns and strands. by a method wherein a remoldable composition obtained through unification by burying and/or napping carbon material whiskers on a knitted fabric and/or an unwoven fabric composed of a reinforcing long fiber is used as a composite. CONSTITUTION:At least a part of carbon material whiskers is stuck to a fiber assembly having a reinforcing long fiber for unification. An unification through burying and/or napping, for example, of a carbon fiber or an aramid fiber is easy for the reinforcing long fiber, the reinforcing long fiber is used preferably. The diameter of the fiber is 20mum or sorter, which is preferably 7mum or shorter. The number of filaments are 500 or more, which are preferably 10,000 or more. A length of the carbon material whickers is set up at 10mm or shorter, which is especially 1mm or shorter and the diameter of them is set up at 5mum or shorter, which is preferably 1mum or shorter. A ratio of the carbon material whiskers to the long fiber is 1-80, which is preferably 5-35 at a weight ratio per unit area. A ratio of a resin weight to the total weight of the long fiber and carbon material whiskers is set up at 1-80%, which is preferably 10-50%.
