Abstract
The present invention provides cured article reinforcing fibers having a shape advantageous in physically bonding the fibers to a hardening material or bringing the fibers into engagement with the hardening material, and also provides a cured article using the fibers. The cured article reinforcing fiber of the present invention has a multilobal cross section with three or more projections. At least one of the projections has a substantially curved end part, and a base part situated toward the center of the fiber has a width smaller than the largest width of the end part. Thus, the fiber particularly has high bending strength. Further, the cured article of the present invention includes a mixture of the cured article reinforcing fiber and a hardening material, and the hardening material has been cured.
