Composite finishing is the process of refining, smoothing, and enhancing the surface of composite materials after they have been formed or moulded. Finishing improves the composite’s appearance, durability, and functionality by creating a smooth, uniform surface or adding protective and aesthetic layers. The finishing process may involve several techniques, including sanding, polishing, coating, painting, and sealing, depending on the intended use of the final product.
Composite finishing is essential in industries like aerospace, automotive, marine to ensure that the final product is visually appealing, durable, and performs well under its intended conditions.
The Exact Group has a state-of-the-art paint facility, with six ovens and two paint mixing rooms.
The key benefits of composite finishing:
- Finishing processes like sealing and coating protect composites from environmental factors such as moisture, UV light, and chemicals, extending their lifespan.
- Sanding, polishing, and painting provide a smooth, high-quality appearance, making the product more visually appealing and professional.
- Finishing adds protective layers to the surface that reduce wear, prevent scratches, and guard against impact, maintaining the material’s integrity.
- Proper finishing protects composites from weather-related damage, such as corrosion, degradation, and colour fading due to UV exposure.
- Finishing removes sharp edges or rough surfaces, reducing the risk of injury for users or handlers of the composite product.
- Finishing processes ensure uniformity across multiple parts, contributing to reliable, high-quality products.
- Smooth, coated surfaces are easier to clean and less prone to accumulating dirt, moisture, or contaminants.
- Specialised coatings, such as anti-slip or anti-static finishes, enhance functionality for specific applications.
The industries that use Composite finishing include:
- Aerospace and Space: Finishing is essential for aircraft components to ensure smooth surfaces, reduce drag, enhance appearance, and protect against UV and weather-related damage.
- Automotive: Composite finishing improves the appearance and durability of body panels, interiors, and structural parts, providing a smooth, high-quality surface and protection against wear.
- Marine: Finishing protects boat hulls and marine equipment from corrosion, UV damage, and saltwater exposure, extending the lifespan of these parts.
- Energy: Wind turbine blades undergo finishing to ensure a smooth surface, reducing air resistance and protecting the blades from environmental damage.
- Medical: Finishing helps protect and smooth medical equipment, prosthetics, and orthotic devices, ensuring comfort and durability for the user.
