Abstract
Embodiments of the disclosure provide a reinforced composite material including a composite material forming a geometric body, and a reinforcement member disposed in the composite material. In some embodiments, the reinforcement member includes (i) at least one elongate metal wire extending at least partially through the composite material, and (ii) at least one barb that extends from the elongate metal wire in a transverse direction to the elongate metal wire.
Claims20
A reinforced cementitious material comprising:
- a cementitious material forming a geometric body comprising a plurality of printed filaments, including a first filament and a second filament that is directly bonded with the first filament such that the second filament is conformed with the first filament,
- a reinforcement member disposed in the cementitious material between the first filament and the second filament when in the flowable state, the reinforcement member comprising:
- (i) at least one elongate metal wire extending at least partially embedded in and extending along at least one of the first filament and the second filament, and
- (ii) a plurality of barbs extending from the elongate metal wire in a transverse direction to the elongate metal wire so that a first barb of the plurality of barbs extends into the first filament and a second barb of the plurality of barbs extends into the second filament;
- wherein the tensile bond strength is at least 500 MPa.
