2. Composite repair - Wikipedia

   en.wikipedia.org/wiki/Composite_repair

   The most important technical challenges in the implementation of a successful composite patch repair are: (a) proper design of the repair patch and the procedures that will be followed, (b) selection of the most suitable materials and tools for the application, (c) careful surface preparation, (d) implementation of the composite patch repair ...

3. High-performance fiber-reinforced cementitious composites

   en.wikipedia.org/wiki/High-performance_fiber...

   This occurrence is hindered by the presence of fiber bridging, a property that most HPFRCCs are specifically designed to possess. Fiber bridging is the act of several fibers exerting a force across the width of a crack in an attempt to prevent the crack from developing further. This capability is what gives bendable concrete its ductile properties.

4. Engineered cementitious composite - Wikipedia

   en.wikipedia.org/wiki/Engineered_cementitious...

   Unlike regular concrete, ECC has a tensile strain capacity in the range of 3–7%, [1] compared to 0.01% for ordinary portland cement (OPC) paste, mortar or concrete. ECC therefore acts more like a ductile metal material rather than a brittle glass material (as does OPC concrete), leading to a wide variety of applications.

5. Carbon-fiber reinforced polymer - Wikipedia

   Controversially, in 2006, cricket bats with a thin carbon-fiber layer on the back were introduced and used in competitive matches by high-profile players including Ricky Ponting and Michael Hussey. The carbon fiber was claimed to merely increase the durability of the bats, but it was banned from all first-class matches by the ICC in 2007. [37]

6. Concrete - Wikipedia

   en.wikipedia.org/wiki/Concrete

   Carbon nanofibers can be added to concrete to enhance compressive strength and gain a higher Young's modulus, and also to improve the electrical properties required for strain monitoring, damage evaluation and self-health monitoring of concrete. Carbon fiber has many advantages in terms of mechanical and electrical properties (e.g., higher ...

   The following are several international standards for fiber-reinforced concrete: [35] BS EN 14889-1:2006 – Fibres for Concrete. Steel Fibres. Definitions, specifications & conformity; BS EN 14845-1:2007 – Test methods for fibres in concrete; ASTM A820-16 – Standard Specification for Fiber-Reinforced Concrete (superseded)

9. Seismic retrofit - Wikipedia

   en.wikipedia.org/wiki/Seismic_retrofit

   Concrete or steel jacketing have been a popular retrofit technique until the advent of composite materials such as Carbon fiber-reinforced polymer (FRP). Composite materials such as carbon FRP and aramic FRP have been extensively tested for use in seismic retrofit with some success.
