PROBLEM TO BE SOLVED: To provide a fiber-reinforced base material for a preform showing excellence in shapability and shape stability, and capable of being easily formed without bulkiness even when adherence is thick. SOLUTION: The base material for the preform is made by letting a binder resin composition adhere to one surface or both surfaces of a sheet-like fiber reinforced base material in a shape of a nonwoven fabric of superfine fibers, the adherence amount ranging 0.1-20 wt.% based on the fiber base material. The binder resin composition contains as a major component a resin having at least two unsaturated groups in a molecule and having a molecular weight of 10,000-95,000. COPYRIGHT: (C)2010,JPO&INPIT |
