About S-Glass Fiberglass Composite

Fiberglass is a topic that carries a lot of diversity. There are many fiberglass materials. Fiberglass is generally described using the name of the glass in the fiber from which it is made. This article is going to relate basic information about fiberglass in general and how S-Glass fiberglass fits into the subject.

One of the More Technically Important Glasses

S-Glass is one of many types used for various fiberglass applications. Like many of the "letter named" types, the letter in the name refers to characteristics of the glass fiber used in the composite. S-Glass fiberglass is among the most technically important types of fiberglass and it has the highest strength, stiffness, and softening point of any commercial reinforcement glass fibers. Because of this, it is used in products where durability and strength are necessary (think aerospace).

S Is for Strength

S-Glass fiberglass is made to be strong. It has a higher tensile strength than other glass fiber. So for applications where strength and durability are critical, this glass fiber is at the top of the selection list.

S-Glass Fiberglass Properties

This type of glass fiber is engineered for for aerospace and defense industries. Additionally, it is used for rigid ballistic armor. Because it is used only in specific industries, the production of S-Glass fiberglass is very low. Hence, it makes up a small portion of all the fiberglass that is produced.

S-Glass fiber has smaller filament diameter which allows for higher ILSS and wet out properties than other types. It is also higher priced than many of the glass types available.

List of Properties

• Very Strong
• Relatively Moisture Insensitive
• Better Mechanical Properties Compared With E-Glass
• Chemically Resistant
• High Stiffness
• Low Density
• Heat Resistant
• Maintains Strength Well

Composition

The typical composition of S-Glass is as follows not including possible small amounts of impurities:

• SiO₂ - 65%
• Al₂O₃ - 25%
• MgO - 10%

Working S-Glass Fiberglass Composite and Durability

Working with S-Glass fiberglass requires some specific equipment, including personal protective equipment and machines to keep the workspace free of dust particles. As mentioned above, silica is one of the substances in S-Glass fiber that is used for the material. Dust control booths, safety glasses, protective gloves, and respirators are just some of the important equipment that is made to help reduce exposure to skin, eyes, nose throat, and lungs.
