Biaxial Glass Fiber Cloth (Biaxial fiberglass Cloth) and Triaxial Glass Fiber Cloth (Triaxial fiberglass Cloth) are two different types of reinforcing materials, and there are some differences between them in terms of fiber arrangement, properties and applications:
1. Fiber arrangement:
– Biaxial Glass Fiber Cloth: The fibers in this type of cloth are aligned in two main directions, usually the 0° and 90° directions. This means that the fibers are aligned parallel in one direction and perpendicular in the other, creating a criss-cross pattern. This arrangement gives the biaxial cloth better strength and rigidity in both major directions.
– Triaxial Fiberglass Cloth: The fibers in this type of cloth are aligned in three directions, usually the 0°, 45° and -45° directions. In addition to the fibers in the 0° and 90° directions, there are also fibers diagonally oriented at 45°, which gives the triaxial cloth better strength and uniform mechanical properties in all three directions.
2. Performance:
– Biaxial fiberglass cloth: due to its fiber arrangement, biaxial cloth has higher strength in the 0° and 90° directions but lower strength in the other directions. It is suitable for those cases which are mainly subjected to bi-directional stresses.
– Triaxial Fiberglass Cloth: Triaxial cloth has good strength and stiffness in all three directions, which makes it show better performance when subjected to multi-directional stresses. The interlaminar shear strength of triaxial fabrics is usually higher than that of biaxial fabrics, making them superior in applications where uniform strength and stiffness are required.
3. Applications:
– Biaxial Fiberglass Cloth: Commonly used in the manufacture of boat hulls, automotive parts, wind turbine blades, storage tanks, etc. These applications usually require the material to have high strength in a specific two directions.
– Triaxial fiberglass fabric: Due to its excellent interlaminar shear strength and three-dimensional mechanical properties, triaxial fabric is more suitable for structural components under complex stress states, such as aerospace components, advanced composite products, high-performance ships and so on.
In summary, the main difference between biaxial and triaxial fiberglass fabrics is the orientation of the fibers and the resulting difference in mechanical properties. Triaxial fabrics provide a more uniform strength distribution and are suitable for applications with more complex and higher performance requirements.
