Title:
SMALL CROSS-SECTION COMPOSITES OF LONGITUDINALLY ORIENTED FIBERS AND A THERMOPLASTIC RESIN AS CONCRETE REINFORCEMENT
Document Type and Number:
WIPO Patent Application WO2003037819
Kind Code:
A3
Abstract:
Small cross-section fiber-reinforced composites are used as reinforcements for concrete. The composites, which are preferably longitudinally oriented continuous fibers embedded in a thermoplastic matrix, are mixed into the wet concrete and poured with the concrete to form a reinforced concrete structure. The properties of the reinforced concrete can be tuned by using mixtures of composites with different reinforcing fibers or mixtures of composites and non-composite fibers
