| description | Provided are a fiber-reinforced composite material shaped product which is isotropic and has excellent mechanical strength and a random mat for use as an intermediate material for the shaped composite material. The random mat includes reinforcing fibers having an average fiber length of 3 to 100 mm and a thermoplastic resin, wherein the reinforcing fibers satisfy the following i) to iii).
i) The reinforcing fibers have a weight-average fiber width (Ww) which satisfies the following equation (1). 0 mm < Ww < 2.8 mm
ii) The reinforcing fibers have an average-fiber-width dispersion ratio (Ww/Wn), which is defined as a ratio of the weight-average fiber width (Ww) to a number-average fiber width (Wn), of 1.00 or more and 2.00 or less.
iii) The reinforcing fibers have a weight-average fiber thickness which is smaller than the weight-average fiber width (Ww) thereof. |
