Dufour advanced technologies

To increase performance and structural strength, Dufour Yachts uses cutting-edge techniques in the design and manufacture of their hulls and decks.

Decks : vacuum infusion technology

The resin sheets are impregnated by air suction. This advanced technology, which is widely used in the aeronautics industry, results in the production of a composite material of outstanding mechanical quality.

Advantages : Significant structural weight / performance ratio.

Injestion technology

Injection moulding consists of bringing resin in a space between two moulds, by injecting it under pressure to reinforce fibre cloths. This complex technique enables all air bubbles to be eliminated and produces a consistentfibre / resin ratio.

Decks are manufactured in one piece, resulting in excellent headroom.

Advantages : Significant gain in weight (better sail rigidity), original quality finish and excellent reliability.

Sandwich hulls : vacuum bonding

The sandwich hull is made up of a set of constituents laminated through pressure and bonding. The type of constituent varies according to the desired effect. Generally speaking, the sandwich hull is made up of a central layer of PVC foam placed between two reinforcements (laminated skin), protected by gelcoat on the exterior surface.

Advantages : Better sound proofing, increased mechanical properties, increased longitudinal rigidity of the hull under equal displacement, no absorption humidity due to the use of PVC foam rather than balsa.
