PROBLEM TO BE SOLVED: To obtain the subject nonwoven fabric capable of providing a fiber- reinforced thermosetting resin composite material(FRP), excellent in impact resistance and suitable as a casing material for computers and electric machinery and apparatus by uniformly distributing bundled fibers composed of many bundled filaments. SOLUTION: This wet nonwoven fabric comprises fibers constituting the nonwoven fabric, in which >=20 wt.% of the fibers are bundled fibers prepared by bundling >=100 filaments. The nonwoven fabric is obtained by bonding interstices among the fibers with a binder having <=30 deg.C glass transition point, covering the fibers therewith and uniformly distributing the resultant bundled fibers. |
