How to Choose the Right Fiberglass Composite for Your Project

Do you have a design in mind and are thinking about bringing it to life in fiberglass? We can help. But before we get started on your project, remember that fiberglass comes in many different forms. To bring your vision to life, we'll need to determine the scope of your project and the kind of fiberglass composite best suited to your needs.

Types of Fiberglass Composite

Fiberglass comes in several forms, each with unique properties best suited for different applications.

• E-Glass Fiber: Known for its electrical insulation properties, lightweight design, and heat resistance, e-glass fiber is widely used to manufacture boat hulls and home insulation.
• S-Glass Fiber: Both strong and flexible, s-glass fiber is widely used in aerospace, sporting goods, and wind turbine blade manufacturing.
• A-Glass: Known for its high thermal resistance, a-glass is commonly used to manufacture insulation.
• C-Glass: This fiberglass composite is known for its exceptional strength and heat resistance. It’s also one of the most expensive forms of fiberglass.
• D-Glass: Strong and flexible, d-glass fiberglass composite is commonly used to manufacture boat hulls, sporting goods, and aerospace components.
• AR-Glass: This is the strongest and most durable fiberglass, ideal for bulletproof vests.
• Roving Fiberglass: Made from fiberglass strands that are twisted together, roving fiberglass composite has a high strength-to-weight ratio, making it ideal for lightweight applications.
• Chopped Strand Mat: This material is made from chopped up and bonded together fiberglass. It’s typically used to manufacture strong, lightweight parts with a smooth finish.

Choosing the Ideal Fiberglass Composite Material

To narrow down your options and select the best fiberglass material, consider the following:

Strength Requirements

As you consider your project needs, think about:

• Tensile strength: How well the material resists being pulled apart.
• Compressive strength: How well it resists being squeezed.
• Flexural strength: Its resistance to bending.

A boat hull, for example, must have both tensile and flexural strength to withstand the rigors of water impact. Automotive components like body panels would require high compressive strength to withstand impact.

Environment

You must also consider the environment in which your fiberglass composite will be used. Consider the temperature it will be exposed to—and also think about normal and extreme conditions. You should also consider chemical and UV resistance, which can degrade some fiberglass over time.

Weight Requirements

Fiberglass composites are known for their high strength-to-weight ratio. That said, materials can vary in density. When choosing your material, consider weight limits and choose a material that offers the most strength while staying within these limits.

Electrical Properties

Does your project involve electricity? You may want to consider using thermal-resistant e-glass.

Thermal Properties

If you are working in areas that experience wide temperature fluctuations, choose a material with appropriate thermal properties. Some fiberglass composites perform well in cold environments, while others excel in high-heat situations.
