As a result of its light weight, high strength, extreme durability, stability under UV exposure, and chemical resistance, FRP (fiber reinforced polyester) has become established as a material of major importance in an ever-increasing number of applications. FRP can be molded into an infinite number of forms and surface finishes and is capable of meeting stringent design standards while at the same time providing major cost benefits.

Fiber reinforced composites typically contain one or more reinforcing fiber materials embedded in plastic resin. In many applications core materials are used to increase the section modulus.

Fiber reinforcements contribute the bulk of strength and stiffness to a composite. There are a number of such materials, including glass fiber, carbon fiber, Aramid fiber, Kevlar® and others, all of which come in a variety of different grades and types. The most widely used reinforcement in the FRP composites industry is glass fiber.

Cores are used to enhance the rigidity and strength of FRP composites. Cored products can have one smooth surface or both surfaces smooth with the core sandwiched in. Typical coring materials are detailed below.

The bulk component of FRP laminates, the plastic resin, serves two purposes: First, it holds the fiber reinforcements in place, and second, under applied force, it deforms and distributes stress amongst these fibers.

The most common type of plastic resin is unsaturated polyester. Other types of resin include epoxies, vinyl esters, phenolics, etc.

Below is a table detailing the characteristics and limitations of the most common types of thermosetting resins.

BFG, over the last twenty-five years, have developed a vast database of raw materials for the composites industry which is updated automatically through BFG's interactive vendor communication procedures, continuous in-house research & development programs and associations with leading international suppliers, research organizations and universities working in the field of composites.

BFG's wealth of knowledge in the composites field is infused into design concepts, the development of new products, and the re-engineering of existing products.  Our design and engineering capabilities enable us to offer and advise our clients on the best solution to fulfill their particular requirements.
