Carbon fiber camper shells
We build one-piece carbon fiber camper shells in Deqing, China — prepreg skins autoclave-cured onto a PMI foam core, with no panel splices, no glue joints and no metal frame. Shells are supplied on their own for your own build, or fitted to pickup, light-truck and heavy 4×4 chassis.
What does “one-piece” actually mean?
Most camper bodies are panels: skins bonded to a frame, then sealed along every joint. A one-piece shell is a single moulded part. The walls, roof and floor come out of the same cure as one continuous structure, so there are no seams to seal, no adhesive lines to age and no frame to conduct heat.
No splices
Six faces cured as one part. Water entry points caused by panel joints do not exist in the structure.
No metal frame
Nothing inside the shell to rust, and no continuous path for heat to travel from the outside skin to the inside wall.
No glue joints
Skins and core are bonded in the cure itself, not assembled afterwards with adhesive.
Stiff as a unit
The shell behaves as one structure under chassis twist instead of flexing joint by joint.
Carbon, aluminum or fiberglass: what actually changes?
The difference buyers feel first is not weight on paper. It is what happens at the joints after five years of sun, salt and washboard roads. This comparison is about structure, not price.
| What to compare | Autoclave carbon monocoque | Aluminum body | Fiberglass panel body |
|---|---|---|---|
| Panel joints | None — one moulded part | Mechanical, sealed | Bonded and sealed |
| Structural frame | None | Required | Usually required |
| Thermal path | No metal, no continuous bridge | Through the frame | At seams and frame |
| Corrosion | No metal in the shell to corrode | At fixings and cut edges | Gel-coat ageing, moisture in the laminate |
| Repair | Composite laminate repair | Panel replacement | Laminate repair |
| Best suited to | Long-distance and off-road use | Road and light off-road | Cost-driven road use |
Weights, wall thickness and insulation values differ by shell size and specification. Ask for the current datasheet for the size you are considering rather than comparing headline figures across suppliers.
How the shell is made
Four steps, and the third one is the reason the first three matter.
| Step | What happens | Why it matters to you |
|---|---|---|
| 01 | Prepreg layup — dry carbon prepreg is cut and laid into the mould by hand | Resin content is set before the part is built, not mixed on the floor |
| 02 | Core placement — PMI foam core positioned between the inner and outer skins | The core carries the load and provides the insulation, in one layer |
| 03 | Autoclave cure — one high-pressure, high-temperature cycle | Skins and core become a single part with a low void content |
| 04 | Trim and finish — openings cut, edges sealed, matte or gloss carbon, optional paint | Cut-outs are made after the structure is cured, so edges stay sealed |
Which chassis can it go on?
The shell is moulded against your chassis dimensions, not adapted to them afterwards. Send the chassis model and wheelbase and we confirm the mould and mounting points before quoting.
Pickup chassis
Single-cab and crew-cab pickups in the F-350 class and equivalent. Our current quotation set has been built around this group.
Light truck 4×4
Light commercial 4×4 chassis where payload and frame width suit a monocoque body.
Heavy-duty 4×4
MAN and Mercedes-Benz based expedition chassis, including the bases used for our off-road motorhome range.
Your dimensions
Length, width and height are set by the mould. Tell us the envelope you need and we say whether it is a new mould or an existing one.
Shell only, or shell on a vehicle?
Both. Most of our camper shell business is shell-only, sold to builders and converters who fit their own interior and systems.
Shell only
Finished monocoque shell, openings cut to your layout, delivered to your workshop. You build the interior and install the systems. Bulk orders and OEM supply are both accepted.
Shell on a vehicle
Shell mounted on a chassis we supply, built out as a complete motorhome and delivered as an announced model with CCC where the finished vehicle requires it.
Shells supplied on their own are components, not complete vehicles. Where a shell is later mounted on a chassis, registration and certification in the destination market are the responsibility of the builder, and requirements differ by country.
How do you check us before you order?
You are buying a structure you cannot inspect until it arrives. These four checks are what a first order should be built on.
| Check | What to ask for |
|---|---|
| Moulding evidence | Photographs of the shell in the mould and after demoulding, with the date visible |
| Section sample | A cut sample showing skin thickness and core, so you can see the laminate rather than a spec sheet |
| Dimensional report | Measured length, width, height and mounting point positions against the drawing you approved |
| Pre-shipment record | Photos of the finished shell, openings and sealing, before it is packed |
Our quotation states the mould, the layup and the finish as separate lines. If a supplier cannot separate them, they are not moulding the shell themselves.
Send the chassis, get a mould answer
Tell us the chassis model, wheelbase and the envelope you need. You get back either an existing mould that fits, or a clear statement that a new mould is required and what that involves.
What we need from you
Chassis make and model, wheelbase, required internal length, and the climate the vehicle will work in.
What you get back
Mould availability, mounting approach, lead time and a quotation with the layup and finish shown separately.
