Vulcanized Fiber Epoxy Canvas Tube
Vulcanized fiber epoxy canvas tube combines a vulcanized-fiber inner layer with an epoxy-impregnated glass-fiber canvas outer layer. The construction is intended for electrical insulation and fuse components where a machinable fiber core and a reinforced outer surface are required.
Construction and selection
| Item | Engineering choice | Confirm for quotation |
|---|---|---|
| Inner layer | Vulcanized fiber for insulation and arc-quenching applications | Inner diameter, wall thickness, length |
| Outer layer | Epoxy-bonded glass-fiber canvas | Canvas grade, resin system, surface finish |
| Machining | Cutting, drilling and turning can be reviewed against the drawing | Tolerances, end geometry, slots and holes |
| Validation | Electrical and dimensional values depend on the final construction | Voltage, temperature, test method and batch quantity |
Typical uses
- Fuse cutout and current-limiting fuse components
- Electrical insulation sleeves and liners
- Machined insulating parts that need a reinforced outer layer
RFQ checklist
Send the drawing or sample, inner and outer diameters, finished length, tolerances, required electrical rating, operating temperature, quantity, packaging requirements and any inspection standard. We will confirm material construction and manufacturability before production.
For comparison, see our vulcanized fiber tube and vulcanized fiber composite fiberglass tube pages. For a fully wound glass/epoxy structure, see the filament wound tube page.

Frequently asked questions
What is a vulcan fiber combined with epoxy canvas tube?
It is a composite built from vulcanized fiber and epoxy-impregnated canvas, combining the machinability of vulcan fiber with extra mechanical strength from the canvas layer.
When is this composite chosen over plain vulcanized fiber?
It is selected when the part needs higher impact and structural strength while keeping good electrical insulation and machinability.
