Composites have permeated our everyday lives: They are used in the cars we drive, golf clubs we swing, pipes that remove wastewater from our neighborhoods and much more. Some applications, such as rocket ships, probably wouldn’t get off the ground without composite materials. Composites offer many benefits. Key among them are strength, light weight, corrosion resistance, design flexibility and durability.
Per pound, composites are stronger than other materials such as steel. The two primary components of composites – fibers and resins – contribute to their strength. Fibers carry the load, while resins distribute the weight throughout the composite part as required.
Composites are light in weight compared to most woods and metals. But why is lighter better? Lower weight contributes to fuel efficiency in cars and airplanes. And lighter objects, ranging from utility poles to bridge decks, are easier to transport and install.
Composites resist damage from weather and harsh chemicals that can eat away at other materials. That makes them good choices for applications that face constant exposure to salt water, toxic chemicals, temperature fluctuations and other severe conditions.
A wide range of material combinations can be used in composites, which allows for design flexibility. The materials can be custom tailored to fit unique specifications of each application. Composites also can be easily molded into complicated shapes.
Simply put, composites last! Structures made with composites have a long life and require little maintenance. Many products made with composites, such as boats, have been in service for more than half a century.
