The Strength of Patterned Carbon Fiber Fabrics
There's more to Patterned Carbon Fiber Fabrics than just great cosmetics. These First Quality fabrics are as strong if not stronger than standard carbon fiber weaves.
Fabricators choose carbon fiber from among common reinforcements for its unmatched strength- and stiffness-for-weight. Typical fabric styles include plain, twill, and satin weaves. But, what about patterns that aren't industry defined? Fibre Glast carries four unique carbon fiber patterns, and since these styles aren't widely used, little is known about their physical properties. To better understand fabric properties, it is important to understand general specifications and terms used to describe composite fabrics.
A Look at the Basics
Filament - Equal to a single strand of carbon fiber. Thousands of filaments make up a fiber, or yarn.
Fiber (Figure 1) – Made up of thousands of filaments that are grouped together.
Tow (Figure 1) – A reference term used to denote the amount of continuous filaments per fiber bundle.
Note: Tow is measured in K (1,000). Example: A 3K means there are 3,000 carbon filaments per fiber. A 12K means there are 12,000 carbon filaments per fiber.
Warp (Figure 2) - The fibers running the length of a woven fabric.
Fill (Figure 2) – The fibers running the width of a woven fabric.
Ends (Figure 3) – Refers to the fibers in the warp direction.
Picks (Figure 3) – Refers to the fibers in the fill direction.
Note: Ends and picks are measured per linear inch. Example: a 12x12 fabric means there are 12 fibers per inch in the warp direction and 12 fibers per inch in the fill direction.
Patterned Carbon Fiber Properties
- The final properties of the Patterned Carbon Fiber Fabrics are not affected by the pattern itself. They are simply woven in a way that creates a custom look.
- Bi-directional tows are aligned in linear fashion, just like a twill or plain weave.
- There is no twisting or bending of tows out of axis to achieve patterns.
- There is no distortion of tows in warp or fill direction.
- Because these patterns have more "floats" (areas where yarn being woven in one direction floats on top of yarn being woven in another direction), there is less bending in the yarn compared to a typical plain weave pattern.
- Heavier filling density in #3222 Wasp gives higher tensile strength in the fill axis.
