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.
Primary high‑voltage insulation, mechanical support, and load transfer
Creepage and clearance management with moisture, contamination, and field‑grading / stress control

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.

Electrical, mechanical, dimensional, hydrostatic, and environmental verification supporting customer qualification requirements and long-term production confidence.
U.S.‑based Scalable Production
Representative Applications
Fiberglass steps in where designers need lightweight, corrosion‑resistant structural shells and non‑magnetic enclosures and strong dielectric protection.

Medical Imaging Systems
Non-magnetic, high-strength fiberglass tubes for MRI tunnels and medical imaging enclosures — where electromagnetic transparency and dimensional stability are both required.

Defense & Submarine Systems
Radomes, torpedo tubes, and other structural composite enclosures for submarine and defense platforms requiring non-magnetic, non-conductive, and environmentally durable construction.

Battery & Electrification Systems
Lightweight fiberglass shields for battery systems in electric and hybrid transportation platforms — corrosion resistant, non-conductive, and machinable to fit complex geometries.

Aerospace & Advanced Structures
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.
