  Fiberglass tissue, also known as fiberglass mat or veil, is a non-woven fabric made from fine glass fibers bonded together with a resin binder. It is commonly used as a reinforcement material in composite manufacturing processes.Here are some key characteristics and properties of fiberglass tissue:

 1. Composition: Fiberglass tissue is primarily composed of glass fibers, typically made from E-glass or C-glass, which are known for their high strength, stiffness, and corrosion resistance. The fibers are randomly oriented within the tissue.

 2. Binder: A resin binder is used to hold the glass fibers together and provide cohesion to the tissue. The binder can be a thermosetting resin such as polyester, vinyl ester, or acrylic, which cures when exposed to heat or chemical catalysts.

 3. Non-Woven Structure: Fiberglass tissue is manufactured using a non-woven process, where the glass fibers are randomly distributed and bonded together without the need for weaving or knitting. This results in a uniform and isotropic structure with consistent mechanical properties in all directions.

 4. Weight and Thickness: Fiberglass tissue is available in various weights (measured in grams per square meter or ounces per square yard) and thicknesses to suit different application requirements. Thicker tissues provide higher strength and stiffness but may require more resin for saturation.

 5. Surface Finish: Fiberglass tissue can have different surface finishes, ranging from smooth to textured, depending on the manufacturing process and intended application. Smooth tissues are suitable for applications requiring a smooth surface finish, while textured tissues may provide better resin flow and adhesion.

 6. Reinforcement: Fiberglass tissue serves as a reinforcement material in composite manufacturing, providing strength, stiffness, and dimensional stability to the final product. It is often used in combination with resin matrices such as polyester, epoxy, or vinyl ester to form composite laminates or structures.

 7. Applications: Fiberglass tissue finds application in various industries such as construction, automotive, marine, aerospace, electronics, and sports equipment. It is used for reinforcing roofing materials, wall panels, pipes, tanks, wind turbine blades, printed circuit boards, and composite structures, among others.

 8. Processing Methods: Fiberglass tissue can be used in different composite manufacturing processes, including hand lay-up, spray-up, resin infusion, pultrusion, and filament winding. It can be easily cut, draped, and molded to conform to complex shapes and contours during fabrication.

  Overall, fiberglass tissue is valued for its versatility, durability, and performance as a reinforcement material in composite manufacturing, offering excellent mechanical properties, corrosion resistance, and design flexibility for a wide range of applications.
