JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
The 6-metre-long Elliot sailing boat is produced by means of the vacuum infusion process to ensure optimum quality. The Lantor Soric core material is used in both hull and deck to create the right stiffness while keeping weight within limits.

In 2008, the International Sailing Federation (ISAF) was looking for the perfect yacht for the women’s match racing event at the 2012 Olympic sailing competition. Seeing that the Elliott 6 met most of the ISAF requirements, Greg Elliott further modified the design to perfect the boat for ISAF and named it the Elliott 6m. At the Olympic meetings held in Spain in November 2008, the Elliott 6m was selected as the Women’s Match Racing Yacht for the 2012 Olympics against some very impressive competition.
This new yacht will be used in fleets purchased by several countries to develop match racing at all levels, as well as for sail and youth training. Another Elliot design, the 5.9m, was the backbone for the Royal New Zealand Yacht Squadron Youth programme for many years, and the sports boat type proved ideal for a number of uses, producing many top sailors and developing talent for the America’s Cup and Round the World races.

The Elliot or ISAF 6 should be reasonably easy to control in terms of cost and production, two important factors that will condition its international take up and acceptance.
The right material at the right place
The 6-metre-long sailing boat will be produced in China by means of the vacuum infusion process. Both deck and hull will be completely infused to control the quality of the boat. More than ever, it is important that every boat rolled out of production has the same weight, properties and sailing behaviour.
The Lantor Soric core material is used in both hull and deck to achieve the right stiffness, while keeping the boat weight within limits.
(.../...) The fastest, lightest and strongest boats in the world – from foiling Moth dinghies to Volvo 70 yachts – are emerging from McConaghy as the company expands to open a facility in China. With a current combined team of 170 staff, the company continues to build strong, light and fast boats, meeting the budget and time demands of yacht owners and designers. This is why McConaghy builds 3.4m foiling Moth dinghies, record-breaking 30-metre Maxis and everything else in between.

The flexible core follows the curvature of the hull perfectly and can be used in places where other core materials are too thick or unable to match with the curves in the design. The channels in the core act as a resin transfer medium to achieve fast infusion that helps control the production rate. To date, half of the participating countries’ boats have already been produced and delivered.
A flexible core
Lantor Soric is a polyester nonwoven material with a compression-resistant cell structure. The pressure-resistant cells, separated by channels, contain synthetic microspheres. These cells do not absorb resin and therefore limit the total resin uptake. Since the cells are pressure resistant, they create thickness in the laminate even when pressure is applied by a vacuum bag.
The channels facilitate resin flow and form a pattern of cured resin with good mechanical properties and excellent bonding to outer skins.
Because of its unique properties and characteristics, Lantor Soric can be used as a thin core, an interlaminar flow medium or a print blocker. It can be used in closed mould processes like vacuum infusion, RTM light, RTM, etc.
Here are few examples and update of these two techniques which can be seen in many application sectors now.
