Vou tentar postar alguma coisa de decente, mas lembra-te Rider88, eu não sou Sr. Enginheiro :lol:
Não restam duvidas de que o "K" significa 1000, mas...
"The skeletal system of a prepreg is the raw fiber. Like yarn, raw/dry carbon fiber comes on spools of intertwined carbon strands referred to as “Tow”. Tow bundles come in a variety of sizes that are categorized by the number of fibers (between 1,000 and 50,000) in the bundle. The result is the common “3K” (3,000 strand) and “12K” (12,000 strand) monichers that are attached to many carbon fiber products. The higher the “K”, the bigger the physical size of the tow and (in the case of woven prepreg) the larger the cosmetic checker pattern of the weave. However, with the exception of all but the thinnest prepregs, the tow size (“K”) has little to no impact on the quality of the carbon used. The fiber type is what matters as it directly effects important mechanical properties like tensile strength (pull strength), modulus (how much a material deflects under load) and strain rate (fiber elongation before failure). Thus, references to “K” have more to do with the aesthetics of the frame or component, while the modulus (Standard, Intermediate or High) of the fiber more directly relates to its stiffness."
Ou seja, o K está efectivamente relacionado com o número de fibras de um tecido mas não é decisivo quanto à qualidade de um quadro. Interessa o tipo de fibra porque está relacionado com as propriedades mecânicas.
