Advanced Fiber Nonwovens

Q:

Surfacing Veils: Will the AFN Group manufacture a nonwoven to my specification or use fibers or other materials that I supply? 

A:

AFN specializes in custom engineers webs for a variety of applications.  We routinely work under Confidentiality Agreements and can utilize your raw materials as long as they meet our health and safety standards.  AFN offers the unique ability to produce small “pilot line” size production on a fully capable 35.5” (90cm) wide production machine. 

Q:

Surfacing Veils: Where are your veils produced?

A:

Hawkinsville, GA.

Q:

Surfacing Veils: What weight and width are AFN surfacing veils produced in?

A:

H&V can deliver materials 35.5” wide (90cm) in extremely light weight veils ranging from 4 gsm to 212 gsm. 

Q:

Surfacing Veils: What is a surfacing veil and how are they used?

A:

Surfacing veils are typically light weight nonwoven fabrics that provide protection against corrosion, abrasion, static discharge, to prevent micro cracks, or to cover up imperfections in a multi-layer buildup of fibrous materials. They are often used to produce a very smooth surface on both the interior and exterior of pipes and holding vessels. Other more exotic materials like holographic fiber and blends of a variety of fibers can be used in decorative applications like composite sporting goods, skis, snowboards, fishing rods, and bicycles helmets, where these fibers serve both as reinforcing components and the final decorative finish.

Q:

Surfacing Veils: What type of binders do your composite materials use?

A:

We use a variety of binders that are designed to be compatible with most composite resins system including epoxy resins. Many of our binders are designed to break down following wets-out forming a very smooth surface.

Q:

Surfacing Veils: What type of material does H&V manufacture for FRP (fiber reinforced plastics) applications?

A:

The Advanced Fiber Nonwoven Group at H&V custom engineers webs for a variety of applications requiring advances synthetic fibers.  AFN scientists carefully select from materials like PAN carbon fibers, metal and metal-coated fibers, various types of fiberglass including ECR and C-glass, aramid and para-aramid fiber; in fact AFN can produce a “paper” using almost any material that can be produced in fiber form. 

Q:

Shielding: Will the AFN Group manufacture a nonwoven to my specification or use fibers or other materials that I supply? 

A:

AFN specializes in custom engineers webs for a variety of applications.  We routinely work under Confidentiality Agreements and can utilize your raw materials as long as they meet our health and safety standards.  AFN offers the unique ability to produce small “pilot line” size production on a fully capable 35.5” (90cm) wide production machine. 

Q:

Shielding: What products do you manufacture for Lightning Strike Protection (LSP)?

A:

A Nickel coated carbon veil will dissipate the strike and not damage the structure; for more detailed information open the white paper on this subject found on this website. 

Q:

Shielding: Do you supply materials that have a specific surface resistivity?

A:

Yes, surface resistivity is express in Ohms per Square (Ω/sq). Consult the data sheets on this website for specific values by grade. 

Q:

Shielding: What types of fibers are used for most shielding applications and why?

A:

Nickel coated carbon for conductivity/reflectivity and carbon/glass blends for low observables for stealth.

Q:

Shielding: What are some of the applications you have developed conductive materials for?

A:

X-Ray tabletops,  Microwave absorbers, Avionics shielding, Locator strips, Fuel tank static dissipation, Aviation lightning strike protection, Wing deicing.

Q:

Shielding: What are some of the types of interference your products can shield against? 

A:

RFI (Radio Frequency Interference) shielding, EMI (Electromagnetic Interference) shielding, MRI (Magnetic Resonance Imaging) shielding, EMP (Electromagnetic Pulse) shielding, ESD (Electro-Static Discharge) electronics protection.

Q:

Shielding: What types of shielding are products does H&V manufacture?

A:

The Advanced Fiber Nonwoven Group at H&V custom engineers conductive webs for a variety of applications requiring conductive fibers. AFN scientists carefully select carbon and metal-coated fibers as the key components in these wet-laid nonwovens, sold under the trade name  Saf’N’Shielded.
