jatkumavakuit

Jatkumavakuit is a Finnish term that translates to "continuous fiber" in English. It refers to a type of fiber material that is not broken into short lengths but instead exists as a long, unbroken strand. These fibers are typically used in composite materials where their continuous nature provides superior strength and stiffness compared to short fibers.

In the context of materials science, continuous fibers are often made from materials like glass, carbon, or aramid. They are manufactured through processes that draw molten material or extrude polymers into very fine filaments. These filaments are then bundled together to form yarns or rovings, which are the forms in which they are typically supplied for composite manufacturing.

The primary advantage of using continuous fibers in composites is their ability to carry loads along their length. When embedded in a polymer matrix, they form a strong and rigid structure. This makes them ideal for applications where high performance is required, such as in aerospace, automotive, sporting goods, and construction. The specific properties of the composite will depend on the type of continuous fiber used, the matrix material, and the manufacturing process. For example, carbon continuous fibers offer very high strength and stiffness at a low weight, while glass continuous fibers provide good strength and are more cost-effective.
