S-Glass Fiber Woven Roving

S-glass fiber woven roving is a premium composite fabric known for its elevated mechanical properties when compared to standard E-glass woven roving. With its higher tensile strength and stiffness, S-glass provides an enhanced structural performance, making it a go-to choice for industries where superior strength and reduced weight are critical. Unlike the more commonly utilized E-glass, which is sufficient for general-purpose applications, S-glass is sought after for advanced applications in aerospace, defense, marine, and high- performance sporting equipment where the demands on material durability and resistance to stress are greater. The use of S-glass woven roving facilitates the creation of components that not only bear heavier loads but also withstand harsher conditions, solidifying its role in the production of high-end, resilient composite structures

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.
