At first glance this might look the same as 2x2 Twill weave, but it’s pattern is actually different. The number of fiber directions vary from two to three. Changing the orientation of the fibers from orthogonal to 60 degrees increases damage tolerance and improves energy absorption. The weave construction is ‘two over, two under’, alternating over and under the axial yarns. Applied for composite reinforcement in aerospace, engineering, sports equipment and automotive racing.
There are many triaxial patterns. The following list will give an overview of its fundamentals.
- * Triaxial weaving is part of the traditional craft of basketry. Its usage dates back to around 5,700 BC in Japan.
- * Triaxial weaving produces a material that is structurally superior to many sorts of rectangular weaving. Since the structural elements run in three directions, the fabric is resistant to shearing forces and doesn't crimp easily.
- * Triaxial fabrics qualities include: good strain resistance, planar shear resistance, tear resistance, abrasion resistance and bursting resistance.
Which applications are suitable for triaxial techniques?
The main selling points of triaxial weaving are:
- 1) Light weight;
- 2) Low material cost;
- 3) Isotropy;
- 4) Shear-resistance.
Triaxial patterns are not very common, which makes them hard to obtain.
Next let's have a glance at some rare patterns.
