Understanding Fiberglass Veil
Fiberglass veil is a thin layer of fiberglass fabric primarily used to enhance the surface finish of composite materials. Its primary purpose is to prevent the print-through of underlying fabrics when resin is applied. This is especially crucial in applications where aesthetics matter, such as in marine and automotive industries.
Types of Fiberglass Veil
-
Surfacing Veil: Commonly used in gelcoat applications, surfacing veils are designed to create a smooth surface and prevent the weave of underlying fabrics from showing.
-
Continuous Strand Veil: This type consists of long strands of fiberglass, providing additional reinforcement to composite structures. It is ideal for applications where strength is critical.
-
Non-Woven Mats: These mats are versatile and can be used in various applications, including reinforcement and core material support.
-
Specialty Printed Veils: Designed for aesthetic purposes, these veils come in various patterns and colors, suitable for decorative finishes.
Applications of Fiberglass Veil
Fiberglass veils are used across multiple industries. Below are some of the most common applications:
- Marine Industry: Used in boat manufacturing to create smooth, durable surfaces resistant to water damage.
- Automotive Industry: In the production of car parts, fiberglass veils help achieve a high-quality finish and reduce weight.
- Construction: Used in composite panels and structures for insulation and reinforcement.
- Aerospace: Provides lightweight yet strong materials for aircraft components.
Benefits of Using Fiberglass Veil
The use of fiberglass veil offers several advantages:
- Improved Surface Finish: Fiberglass veils provide a smooth surface, enhancing the appearance of the final product.
