Structure of our Carbon Fiber Tube:
0° ORIENTATION
-if a part will only be loaded in one direction it is Ideal to have all the fibers oriented in that direction. pultruded rod and tubing are examples of a part that contains only 0° fibers
90 °ORIENTATION
-as previously mentioned, 90° layers are often added to tubes to make them more resistant to buckling and crushing. High concentrations of 90° or “hoop” layers can also be found in pressure vessels
+/- 45 ° ORIENTATION
-45° layers serve different purposes depending on the application. You’ll almost always see a +45° paired adjacent to a -45° layer. This is to keep the laminate “balanced” and from forcefully twisting when loaded.
