Multi-Axial S-Glass Fiber Fabric

These fabrics are made from S-glass, which is a high-strength and high-modulus glass fiber. It is superior to E-glass, which is the most common glass fiber, in terms of tensile strength, modulus, and temperature resistance. Multi-Axial S-glass fabrics have multiple layers of fibers oriented at different angles, which are stitched or bonded together. This multi-directional reinforcement provides enhanced strength and stiffness in various directions, making it ideal for applications requiring improved impact resistance and durability.

Tensile Strength

S-glass fibers possess a higher tensile strength than E-glass fibers. The tensile strength of S-glass is typically about 4,500 MPa (650 ksi), which is approximately 40% higher than that of E-glass, which has a tensile strength of about 3,450 MPa (500 ksi). This makes S-glass fibers more suitable for applications where high strength is critical.

Modulus of Elasticity (Stiffness)

S-glass has a higher modulus of elasticity compared to E-glass, indicating that S-glass is stiffer. S-glass’s modulus is typically around 87Gpa(12.6Msi), while E-glass has a modulus of about 72 GPa (10.5 Msi). The higher modulus means that S-glass fibers are less likely to deform under load, making them ideal for high-performance applications.

Temperature Resistance

S-glass fibers retain their high strength and modulus at higher temperatures compared to E-glass. S-glass can be used at temperatures up to about 1000° F (540°C), significantly higher than E-glass, which starts to lose its mechanical properties above 600°F (315°C). This makes S-glass a better option for applications involving high thermal loads.

Impact Resistance

S-glass has better impact resistance due to its high-energy absorption capability. This means that structures made with S-glass composites can withstand more impact before failure, which is crucial for applications such as military vehicles, aerospace, and sporting goods.

Usages:

• • High-performance sporting goods (surfboards, hockey sticks, racing shells)
• • Military and defense applications (ballistic armor, helmets)
• • Aerospace components (aircraft structural parts, panels)
• • Marine applications (boat hulls, masts where high strength and impact resistance are critical)
