Short Fibers with High-Strength Results

Mix this milled glass with any resin, body filler, or casting material to increase strength, bulk, and dimensional stability for parts.

  • Milled glass helps reduce shrinkage and increase moduli for parts, so it's popular for electrical/automotive components.
  • It is often used with vinyl ester resin as a corrosion-resistant, blister repair putty for deep boat hull damage (a ketchup consistency delivers best results).
  • Both fiber length and bulk density are controlled by the screen size116" refers to the hole diameter of the hammermill screens used to mill the fibers, and lengths may vary up to this dimension.

For similar properties, but smaller fibers, see the 132" Milled Glass Fiber, #38.

This filler is compatible with epoxy, polyester, and vinyl ester resin systems. Add filler after adding catalyst to resin.

Add fibers to resin 5% by weight.

116" milled glass fibers are fine glass fibers that have been processed and milled to achieve a specific size range. They are typically around 1/16th of an inch (approximately 1.6 mm) in length. Here is some information about the use of 116" milled glass fibers in composites:

  1. Reinforcement: 116" milled glass fibers are commonly used as a reinforcement material in composite applications. They are added to composite matrices, such as resins, to improve the mechanical properties of the material.
  2. Enhanced Strength and Stiffness: The addition of 116" milled glass fibers increase the strength and stiffness of the composite. These fine fibers distribute and transfer stress within the material, improving its load-bearing capacity and resistance to deformation.
  3. Improved Impact Resistance: 116" milled glass fibers enhance the impact resistance of composites, making them more resistant to sudden forces or impacts. The fibers absorb and distribute energy, reducing the risk of cracking or fracturing under impact loads.
  4. Dimensional Stability: Adding 116" milled glass fibers to composites can help improve dimensional stability by minimizing shrinkage and expansion. They provide reinforcement and structural integrity to the material, reducing the likelihood of warping or distortion due to changes in temperature or humidity.
  5. Improved Surface Finish: The use of 116" milled glass fibers can help achieve a smoother surface finish in composites. These fine fibers fill voids and imperfections, resulting in a more uniform and aesthetically pleasing appearance.
  6. Increased Wear Resistance: 116" milled glass fibers improve the wear resistance of composites, making them more durable and resistant to abrasion. The fibers enhance the material's ability to withstand friction and extend its service life in demanding applications.
  7. Processability: 116" milled glass fibers can be easily incorporated into different manufacturing processes, including injection molding, compression molding, and filament winding. They can be uniformly mixed with the matrix material, facilitating consistent dispersion and reinforcement throughout the composite.

It is important to note that the specific properties and performance of composites using 116" milled glass fibers will depend on various factors, including the fiber content, fiber orientation, matrix material, and processing conditions.


Fillers, when ordered alone, will typically ship in a small or medium box. Where possible, we will combine ordered items to reduce the number of boxes shipped.

I do commercial roofing I mixed the product with silicone for repairs as reinforcements it worked excellent

Make super strong

I used this for making a bedding paste to fuse separate components together. It's easy to blend and very - very strong.

Good product.

Extremely quick delivery of products ordered. Fantastic packaging. Easy to use ordering system. Highly recommended

Great high strength filler

Milled fiberglass is a great filler for use with epoxies and fills a gap left by other fillers when it comes to strength. Consistent size, easy to work with and excellent wettability.
