Fiberglass Filament-Wound Tubes

InsulWynd® U.S. Manufacturer Fiberglass Filament-wound Tubes

InsulWynd® filament-wound fiberglass tubes and custom FRP products are engineered for applications requiring high strength-to-weight ratios, excellent dielectric properties and high corrosion resistance.

Machinable to close tolerances with CNC precision

Extreme temperature tolerance

Excellent electrical insulation with controlled dielectric properties

Lightweight. Corrosion‑resistant.

Strength‑Driven Fiberglass Tubes for Extreme Demands

Filament winding is one of the most efficient methods for producing lightweight, high-strength composite structures. By controlling material system type, winding pattern, resin system, and geometry, InsulWynd® components can be tailored to meet demanding electrical, mechanical, environmental, and corrosion-resistance requirements.

High strength‑to‑weight, engineered directional performance

Corrosion, chemical, and dielectric protection

Non‑magnetic, RF‑transparent, and flame‑retardant options up to UL 94 V‑0 / 5VA

Fiberglass Tube Components

The InsulWynd® line is built around filament-wound composite structures using fiberglass reinforcements in epoxy resin systems, with variants incorporating E-glass, S-glass, Kevlar, and carbon fiber depending on the application.

Insulate. Support. Protect.

Multifunction Fiberglass for Critical Components.

Filament-wound fiberglass serves structural, dielectric, and environmental protection functions — often simultaneously — within electrical, defense, and medical systems.

Unified Insulation Stack

Fiberglass, Epoxy, and Wood Under One CK Quality System

InsulWynd® tubes and panels frequently work alongside InsulVolt® cast epoxy and InsuLam® laminated wood in multi-material assemblies. Fiberglass provides the structural shell or non-magnetic enclosure; cast epoxy handles primary dielectric insulation; laminated wood contributes mechanical toughness where compressive loads are highest.

All three technologies run under one quality system at CK Composites, which simplifies qualification and supply chain management for OEMs sourcing across the full stack.

Custom Fiberglass-wound Tubes

Design & Engineering Support

CK Composites’ engineering team works with customers on winding angle selection, resin system compatibility, and dimensional requirements from the design stage — not after the first article fails. If you’re developing a new program or running into performance or volume challenges with a current supplier, that’s the kind of problem we’re built to work through.
