Benefits of Aerospace Composites Manufacturing

Thermoset composite materials are produced in a high-temperature, high-pressure lamination process that sets their chemical and physical properties. They are ideal for use in high-impact, demanding environments.

Thermoset composite materials offer multiple benefits to the aerospace industry, including:

Weight: Thermoset composites are lightweight and weigh much less than metal. Due to their reduced weight, the materials help to reduce fuel use and emissions, improving costs.
Strength: The materials also have a high strength-to-weight ratio. Glass epoxy composites, such as G10, have a tensile strength-to-weight ratio nearly twice that of aluminum. Due to their strength, composites are often used for the structural components of aerospace vehicles, such as wings and floor beams.
Insulation: Composites offer thermal and electrical insulation for aerospace applications, protecting equipment from high heat and electrical currents. Composite materials, like G10 or FR4, don’t conduct electricity or heat well, allowing them to act as superior insulators.

Corrosion resistance: Corrosion is the gradual destruction of materials due to exposure to oxygen. Many metals corrode and become weak over time. Thermoset composites are corrosion-resistant. A resin binder can also be added to the material during manufacturing to enhance its corrosion resistance.
Fatigue resistance: After repeated bending, metals can undergo a process under which microfractures grow to the point where the material fatigues and breaks.
Temperature tolerance: Vehicles in the aerospace industry get exposed to high temperatures and must withstand extreme heat and cold. Thermoset composites have a high-temperature tolerance and can withstand an aircraft’s extreme temperatures.
Flexibility: Atlas Fibre works with each of our customers to create materials and parts that fit their unique designs. We can machine phenolic and glass thermosets plus PEEK thermoplastic for the aerospace industry.
