Fiber-reinforced polymer (FRP) composite materials are highly durable, lightweight materials used in many industries, including wastewater treatment, chemical processing, military, mining, architecture, agriculture, infrastructure and more. One of the biggest benefits of FRP is its versatility. It is available in many different combinations of reinforced fibers, resins, and additives, each of which offers its own unique advantages that make it suitable for different applications.
FRP refers to a polymer that has been reinforced with fibers such as glass fibers, carbon fibers, polyester fibers, and natural fibers. When these fibers are combined with resins, the composite takes on new characteristics that improve its overall functionality and quality. These characteristics include strength, stiffness, corrosion resistance, reduced thermal conductivity, electrical insulation and more.
FRP exhibits many beneficial qualities that make it a suitable alternative to more traditional construction materials such as wood, steel, concrete and aluminum. For example, it offers the same strength as steel, but at a fraction of the weight. FRP is also durable, easy to manufacture and install, affordable, flexible, low maintenance, and a great insulator. These properties make FRP a popular choice for a wide range of applications, both indoors and outdoors.
There are several ways to manufacture FRP, depending upon the finished product’s size, function, and aesthetics, as well as the volume of the order. These methods include:
Eco-friendly and affordable, this continuous manufacturing technique uses rollers to pull fibers through a resin bath to infuse them with polymer. The fiberglass strands then move through a heated die, which cures the resin around the fibers with a consistent cross-section.
Though slower than some other options, vacuum infusion is customizable and ideal for large components such as turbine blades and bridges. Dry fibers are placed into a mold and subjected to complete vacuum conditions. The liquid polymer resin is carefully added to the mold; then it cures to create a solid part.
Ideal for parts that will face high operating pressures, this automated process places resin-soaked, continuous strands of fiber over a rotating cylindrical mold.
As one of the original manufacturing methods for FRP, a skilled technician places the reinforcing fiber into an open mold and manually applies the resin. Though this method is fairly inexpensive, it’s time-consuming and labor-intensive, making it more appropriate for samples and prototypes than for large production runs.
FRP can be made with a variety of different resins depending on the intended application. At Creative Composites Group, we offer the following types of resin materials:
