Fiberglass

Fiberglass is a composite material made up of extremely fine fibers of glass. It is a versatile material that is used in various applications due to its strength, durability, and lightweight nature.

Composition

Fiberglass is made from molten glass that is drawn into fine fibers. These fibers are then woven together to create a fabric-like material. The fibers are usually mixed with a plastic resin to create a strong and durable composite material.

Properties

Fiberglass has several important properties:

Strength: Fiberglass is known for its high tensile strength, which makes it a popular choice for applications where strength is important.
Lightweight: Despite its strength, fiberglass is relatively lightweight, making it ideal for use in various products and structures.
Corrosion-resistant: Fiberglass is resistant to corrosion, making it suitable for outdoor and marine applications.
Insulating properties: Fiberglass is a good insulator, both electrically and thermally, which makes it useful in applications where insulation is required.

Uses

Fiberglass is used in a wide range of applications, including:

Boats and marine equipment
Automobile body panels
Aircraft components
Water and wastewater tanks
Building construction, including insulation and structural components
Sports equipment, such as hockey sticks and fishing rods

The resources above cover the following skills:

EARTH AND SPACE SCIENCE

Earth’s Systems

Analyze and interpret data (e.g., tables, graphs, maps of global and regional temperatures; atmospheric levels of gases such as carbon dioxide and methane; rates of human activities) to describe how various human activities (e.g., use of fossil fuels, creation of urban heat islands, agricultural practices) and natural processes (e.g., solar radiation, greenhouse effect, volcanic activity) may cause changes in local and global temperatures over time.

Earth and Human Activity

Analyze evidence (e.g., databases on human populations, rates of consumption of food and other natural resources) to explain how changes in human population, per capita consumption of natural resources, and other human activities (e.g., land use, resource development, water and air pollution, urbanization) affect Earth’s systems.

Implement scientific principles to design processes for monitoring and minimizing human impact on the environment (e.g., water usage, including withdrawal of water from streams and aquifers or construction of dams and levees; land usage, including urban development, agriculture, or removal of wetlands; pollution of air, water, and land).
