  2. Carbon fibers - Wikipedia

    en.wikipedia.org/wiki/Carbon_fibers

    Carbon fiber sunglasses temples and carbon fiber bicycle frame tube. Carbon fiber can have higher cost than other materials which has been one of the limiting factors of adoption. In a comparison between steel and carbon fiber materials for automotive materials, carbon fiber may be 10-12x more expensive. However, this cost premium has come down ...

  3. Metal matrix composite - Wikipedia

    en.wikipedia.org/wiki/Metal_matrix_composite

    For example, carbon fibers are commonly used in aluminium matrix to synthesize composites showing low density and high strength. However, carbon reacts with aluminium to generate a brittle and water-soluble compound Al 4 C 3 on the surface of the fiber. To prevent this reaction, the carbon fibers are coated with nickel or titanium boride.

    Tail of a radio-controlled helicopter, made of CFRP. Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers (Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon ...

  5. Carbon fiber testing - Wikipedia

    en.wikipedia.org/wiki/Carbon_fiber_testing

    Carbon fiber testing is a set of various different tests that researchers use to characterize the properties of carbon fiber. The results for the testing are used to aid the manufacturer and developers decisions selecting and designing material composites, manufacturing processes and for ensured safety and integrity.

  6. Fiber - Wikipedia

    en.wikipedia.org/wiki/Fiber

    Fiber (also spelled fibre in British English; from Latin: fibra) [1] is a natural or artificial substance that is significantly longer than it is wide. [2] Fibers are often used in the manufacture of other materials. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene.

    In an online conversation about aging adults, Google's Gemini AI chatbot responded with a threatening message, telling the user to "please die."

  8. Carbotanium - Wikipedia

    en.wikipedia.org/wiki/Carbotanium

    This is because carbon fiber has the highest strength-to-density ratio of any current fiber and titanium has the highest strength-to-density ratio of any current metal. As a result, carbotanium can withstand temperatures up to 315 °C. [2] The material properties of carbotanium are a mixture of those of a titanium alloy and a carbon fiber.
