Chopped Fibers

High-performance fibers engineered for demanding applications where strength, thermal stability, weight reduction, and long-term durability are critical. Rocket-Fibers offers a range of advanced materials including aramid, UHMWPE, liquid crystal polymer (LCP), carbon, and PBI fibers for composites, textiles, and engineered systems.

Aramid Fibers

High strength with excellent cut, thermal, and chemical resistance across a wide range of environments.

Includes Kevlar®, Technora®, and Nomex® for protective textiles, industrial applications, and high-temperature systems.

UHMWPE (Dyneema® / Spectra®)

Extremely high strength-to-weight ratio with low elongation and excellent moisture, UV, and abrasion resistance.

Ideal for lightweight, high-strength applications including ropes, reinforcement, and load-bearing systems.

Carbon Fiber

High modulus and rigidity with exceptional stiffness-to-weight performance.

Widely used in composite reinforcement and structural applications requiring dimensional stability and strength.

LCP Fibers (Vectran™)

High strength with low creep, good abrasion resistance, and zero moisture regain.

Ideal for dimensionally stable applications requiring long-term load retention and environmental resistance.

PBI Fiber

Exceptional thermal stability with continuous use capability in extreme heat environments.

Used in high-temperature protective apparel and extreme thermal applications.

Aramid fibers are commonly selected for applications requiring strength and heat resistance, while UHMWPE fibers are used where weight reduction and high strength are critical. Carbon fiber provides stiffness and structural reinforcement, while LCP fibers such as Vectran™ offer low creep and dimensional stability in demanding environments.

PBI fiber is reserved for the most extreme thermal environments, offering unmatched heat resistance where traditional high-performance fibers reach their limits.

Frequently Asked Questions

Q: Can you cut fibers to a custom length for my process? +
Yes. Beyond our standard lengths, we produce custom cut lengths to match your molding, compounding, or coating process. Share your target length and fiber type and we can confirm feasibility and tolerance.
Q: What cut length tolerance can you hold? +
Our precision-cutting holds tight, repeatable length tolerances, which matters for consistent flow and mechanical results in automated or high-volume production. If your process has a specific tolerance requirement, tell us and we will confirm we can meet it before quoting.
Q: Which fibers are available in chopped or precision-cut form? +
We supply cut carbon, aramid (including Kevlar), UHMWPE, Vectran, and other high-performance fibers. Each behaves differently in a matrix, so we can help match the fiber to whether you need stiffness, impact resistance, conductivity, or low weight.
Q: Can you supply cut fibers with a coating or surface treatment? +
Yes. We offer coating services alongside cutting, so fibers can arrive treated for improved dispersion, bonding, or handling in your compound. This lets you consolidate cutting and finishing with a single supplier.
Q: What is the minimum order quantity for cut fibers? +
Minimums depend on the fiber and cut length, and we deliberately supply quantities that make sense for smaller buyers as well as large manufacturers. Contact us with your fiber, length, and volume and we will confirm the MOQ and pricing.
