Surfacing veil is a thin, lightweight layer of fiberglass or other high-strength non-woven fiber material that is used as a surface layer in composite materials. Surfacing veils strengthen the resin-rich surface of composite parts, creating a strong bond with the underlying laminate and enhancing surface appearance by masking the reinforcing fiber pattern. This reduction in pattern print-through allows for the highest quality surface to last over time.

Surfacing veil is typically used in the construction of sandwich panels, where it is laminated to the top and bottom skins of the panel to provide a smooth, continuous surface finish. The surfacing veil helps protect the core material from damage and provides a cosmetic finish that can be painted or polished to achieve a desired appearance. In addition to its protective and cosmetic functions, the surfacing veil increases the overall stiffness and strength of the composite panel by providing a load-carrying capacity to the skin layers.

Surfacing veils are commonly used to ensure an optical smooth surface in pipes and tanks, wind turbine blades, aerospace and industrial applications. They are also used in the production of surfboards, snowboards, and in many marine applications.

  1. Surface Texture: Surfacing veils can be manufactured with different surface textures, ranging from smooth to textured. The choice of texture depends on the desired appearance and functionality of the composite part. Smooth surface veils provide a glossy finish, while textured veils can help to hide surface imperfections or create specific visual effects.
  2. Thickness: Surfacing veils are available in various thicknesses, typically ranging from 0.1 to 0.5 millimeters (about 0.003-0.02 in). The thickness selection depends on factors such as the desired level of surface smoothness, the complexity of the part's shape, and the overall laminate thickness.
  3. Compatibility: Surfacing veils are compatible with different types of resin systems, including polyester, epoxy, vinyl ester, and more. They can be used with various types of composite reinforcements, such as fiberglass, carbon fiber, or aramid fibers.
  4. Improved Surface Quality: In addition to providing a smooth surface finish, surfacing veils can help to minimize surface defects, such as pinholes, air bubbles, or fiber print-through. They act as a barrier layer, preventing the resin from penetrating through the fibers and reducing the visibility of the underlying reinforcement.
  5. Resin Distribution: Surfacing veils can assist in the even distribution of resin throughout the composite laminate. By promoting resin flow, they help to improve the impregnation and wetting of the reinforcement fibers, resulting in a more uniform resin-to-fiber ratio, and enhanced overall laminate performance.
  6. Enhanced Durability: Surfacing veils contribute to the durability of composite parts by providing an additional layer of protection against environmental factors. They can help to reduce water absorption, resist UV degradation, and enhance resistance to chemicals, thereby improving the longevity of the composite structure.
  7. Easy Application: Surfacing veils are typically applied during the lay-up process of composite manufacturing. They can be easily draped over the mold or applied as a separate layer between the reinforcement layers. The veils conform to complex shapes and can be easily cut or trimmed to match the contours of the part.

Overall, surfacing veils offer several advantages in terms of appearance, protection, and performance enhancement for composite parts. Their ease of application and compatibility with different resin systems make them a valuable component in composite manufacturing processes across various industries.
