The Most Common Types of Fiberglass and How They Are Used in Aviation

July 25, 2024 robert bell Aerospace

Fiberglass is a versatile material that has become integral to various industries, a result of its lightweight properties, high tensile strength, and resistance to numerous environmental factors. One specific industry that has seen a great rise in demand for fiberglass in recent decades is aviation, where such materials are used for aircraft construction and structural design. Understanding the most common types of fiberglass and their specific applications within aviation can provide insight into why this material is so valued, so read on as we offer a simplified overview.

One of the primary forms of fiberglass used in aviation is fabric fiberglass. This type is woven into a cloth-like material, which can then be layered and bonded with resin to create strong, durable composites. Fabric options are advantageous for being highly adaptable, offering significant strength without adding excessive weight to the overall assembly. This makes them ideal for constructing various parts of an aircraft where optimal strength-to-weight ratios are a concern, such as fuselage sections, wings, and control surfaces. The lightweight nature of fabric fiberglass helps improve fuel efficiency and overall aircraft performance during flight, while its strength ensures that the structures can withstand the stresses of flight.

Another common type of fiberglass present in aviation design is chopped strand mat (CSM), which consists of randomly oriented glass fibers that are held together by a binder. CSM is typically used in conjunction with resin to create fiberglass-reinforced plastic (FRP). In aviation specifically, chopped strand mat materials are relied on for creating structural components that require uniform strength and rigidity, as well as for intricate parts where their ability to conform to complex shapes is beneficial.

Woven roving is another variant of fiberglass commonly used in aviation, made from continuous glass filaments woven into a heavy fabric. Woven roving is known for its excellent strength-to-weight ratio, making it suitable for applications where durability and weight reduction are big concerns. In aircraft construction, woven roving is often used to reinforce structural components, providing additional strength to areas that experience high stress. This reinforcement helps extend the lifespan of the aircraft and reduces the need for frequent maintenance.

Fabric-coated fiberglass represents an advanced form of this material, combining the inherent benefits of fiberglass with additional coatings to enhance performance. These coatings can provide increased resistance to heat, chemicals, and abrasion, making fabric-coated fiberglass ideal for specific aviation applications. For instance, this type of material is often used in areas exposed to extreme temperatures, such as engine compartments and exhaust systems, to maintain integrity and performance.

Another significant type of fiberglass used in aviation is continuous filament mat (CFM), which is created from continuous strands of glass fiber that are laid randomly and bonded together. Continuous filament mat materials are beneficial for their high strength characteristics and excellent impact resistance, making them suitable for applications where durability is the biggest concern. In aviation, these materials are often used for creating robust exterior panels and other structural components that will be faced with varying levels of impact and stress, contributing to the safety and longevity of the aircraft.

Fiberglass is also employed in the form of pre-preg materials, where the fabric is pre-impregnated with resin. This is particularly advantageous in aviation settings, because it ensures consistent resin distribution and simplifies the manufacturing process. Pre-preg fiberglass is often used for high-performance aircraft components that require precise material properties that are made possible through a controlled resin content.

The applications of fiberglass in aviation are vast and varied, its use extending beyond the construction of aircraft bodies to include components such as radomes, which protect radar systems, and fairings, which improve aerodynamics. Fiberglass is also used in the production of aircraft seating, cargo containers, and other interior elements that are important to overall operations.
