Fibreglass Monocoque

Wingamm is the no.1 manufacturer in the world of campers with a fibreglass monocoque bodywork as standard since 1977.

As illustrated by the word itself, a fibreglass monocoque bodyshell is moulded as part of a single block without any joints.

 

A ONE-PIECE BODYWORK IS THE ONLY ONE TRULY GUARANTEED AGAINST WATER LEAKS.

 

In partnership with external companies specialising in moulding fibreglass products, since 1977 Wingamm has been experimenting with all kinds of fibreglass and moulding technologies, constantly seeking better quality. In 2009 it completed the ambitious project to create entrance door, hatches and lockers entirely of fibreglass with a skilful automotive-style design.

 

coibentazione garantisce notevoli prestazioni anche in termini di comfort termico ed acustico.
Wingamm’s monocoque bodyshells are one-piece structures, which as they have no joins eliminate the risk of water leaks, and have an extremely high finish inside and outside. The excellent insulation ensures considerable performance levels also in terms of thermal and acoustic comfort.

INFILTRATIONS

The fact that there are no joints between the walls and roof of the monocoque is the only true GUARANTEE AGAINST WATER LEAKS.

SAFETY

The monocoque is a SELF-BEARING monocoque structure with resistance to collisions far higher than the structure of a traditional motorhome with assembled panels.

ACOUSTIC COMFORT

The monocoque is made from a single piece, with no additional screwed-on straps/skirts in light ABS. This ensures great acoustic comfort while driving.

DURABILITY

The structure of the monocoque has a sandwich design: FIBREGLASS + POLYURETHANE FOAM + FIBREGLASS.

There are no panels or wooden slats that might deteriorate over time.

INSULATION

Thanks to their micro-cellular structure, the POLYURETHANE FOAM contained inside the two fibreglass sheets forming the monocoque provide the best thermal insulation – the only one used to make equipment for the so-called “cold chain” (cold stores).

STABILITY ON THE ROAD

A limited size, an aerodynamic design, a short overhang and balanced weight ensure great stability on the road.

FIBREGLASS

Fibreglass is a composite material consisting of glass fibre in the form of fabrics or TNT and thermosetting resin, generally liquid and with a polyester, vinylester or epoxy base.

 

Chemicals are added to the resins, thereby leading to polymerisation at room temperature and the resins are spread on glass fabrics with bristle rollers and brushes or by using more sophisticated techniques, thereby impregnating them.

 

The solidification of the resins (matrices) incorporates the glass fibres (reinforcements), thereby forming fibreglass. By performing the spreading process on a mould, one can reproduce the drawing to make products with a varying size, thickness, sturdiness (several reinforcement layers), solidity, weight and colour (by adding pigments to the resins).

 

Starting in the 1950s, fibreglass has been used for a number of applications to make objects exposed to the elements, namely: cars and boats, pools, tanks and skylights.

 

Owing to its excellent solidity, resistance to stress and lightness, fibreglass is also used in the aeronautical sector, to make wind turbines and sports equipment.

 

Thanks to its corrosion resistance in basic environments like sea water, fibreglass is used to produce pipes, tanks, silos and grids.

 

In the industrial field, fibreglass is also employed to make atmospheric tanks for liquids.

 

Due to another property, i.e. its poor electrical conductivity, fibreglass is often used to make covers for electro technical equipment.

 

Moreover, as well as for racing vehicles (which need to be light), fibreglass is also used to create additional components merely with an aesthetic value for bodyworks or hulls.

POLYURETHANE

Polyurethane is a polymer obtained from an exothermic reaction between an isocyanate (MDI, Methylene diphenyl diisocyanate, or TDI, toluene diisocyanate) and a polyol (polyether or polyester). Polyurethane is the most versatile plastic material. Polyurethane foam is obtained through a reaction process with an expansion stage involving suitable expanding elements.

 

POLYURETHANE FOAM IN THERMAL INSULATION
The success of rigid polyurethane foam in the building industry’s thermal insulation sector derives from some key properties of the material:

  • excellent thermal insulation determined by the lower available thermal conductivity
  • high mechanical PROPERTIES
  • dimensional stability at high and low temperatures
  • inertia to the most common chemical agents
  • excellent processability, which allows for stable and durable coupling with almost all materials used in the building sector
  • suitable reaction to fire for the intended uses and in line with the strictest regulations in force
  • compatibility with mankind and the environment ensured by the physical and chemical inertia of the foam

 

Thanks to its microcellular structure, polyurethane foam is the best thermal insulator.

 

This feature helped revolutionise the building systems of all the equipment forming the so-called “cold chain”.

 

Indeed, from the freezing tunnel to the cold store, windows and display counters, transport by road or rail up to friges for domestic use, the only thermal insulator used is polyurethane foam.
