S-Glass Fabric

S-glass fabrics are made of direct-sized yarns which can be compatible with epoxy or vinyl ester with out heat-cleaning process. This versatile fabric finds extensive applications in industries such as aerospace, automotive, marine, and sports equipment. Specifically engineered for use in prepreg manufacturing, laminating processes, and vacuum infusion techniques, S-glass fabric enhances the structural integrity and durability of composite components. Its compatibility with various production methods makes it an ideal choice for creating advanced composite structures with superior mechanical properties and enhanced.

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.
