TLDR
A reinforced composite of a castable matrix having discontinuous reinforcing filaments randomly distributed within the matrix which reinforce the matrix and which are bonded to the matrix chemically and/or mechanically is described in this paper.Abstract:
A reinforced composite of a castable matrix having discontinuous reinforcing filaments randomly distributed within the matrix which reinforce the matrix and which are bonded to the matrix chemically and/or mechanically. The filaments have a non-round cross sectional configuration with width and thickness dimensions and with a width-to-thickness ratio of not greater than about five. For maximum reinforcing strength, the filaments should have an ultimate tensile strength at least equal to the average tensile stress developed in the filament at bond failure. The characteristics of the filaments are such as to permit dry admixing with the castable matrix material. A method of making the reinforced composite and apparatus for and a method of coating the filaments are disclosed.read more

Optimized geometries of fiber reinforcements of cement, ceramic and polymeric based composites
TL;DR: In this article, continuous or discontinuous fibers and bars having optimized geometries for use in the reinforcement of cement, ceramic and polymeric-based matrices are claimed to increase the ratio of surface area available for bond between the fiber and the matrix to the cross-sectional area of fiber.
