Best Regards to all we met at JEC 2011 in March.
The JEC Show Paris 2012 will be held from the 27th to 29th March 2012.
If you would like to arrange a meeting to discuss how we can help you, please contact us.
November 2011: "Composite Filament Winding" Published
We have been pleased to contribute to COMPOSITE FILAMENT WINDING Edited by S.T. Peters and published by ASM International (ISBN-13: 978-1-61503-722-3). Because of our acknowledged expertise in advanced filament winding software we were invited to provide a chapter entitled "Programming Techniques, Computer-Aided Manufacturing, and Simulation Software".
THIS IS THE FIRST CONTEMPORARY BOOK to treat filament winding with a focus on automation. The purpose of this book is to provide detailed procedures for automated filament winding for complex shapes, to chronicle the progress that has been made in robotic filament winding along with ancillary processes that support the deposition process. It is also to show what has and what can be done to advance the process and science of low-cost composite fabrication by filament winding.

Sections played a key role in the development of
these Fully Wrapped Non-Round road tankers.
Road tankers are used all over the world for transportation of water, edible oil, milk, chemicals and petroleum products. Traditionally, road tankers have a steel or aluminium body, with or without rubber lining inside. Metallic tankers are heavier with 12 to 15% of the liquid they carry and the rubber lining requires frequent repair and relining every four years.
Unlike pressure vessels, road tankers for transportation of liquids under gravity are made of double-‘D’-shaped cross-sectional profiles in order to keep the overall centre of gravity low for better stability and vehicle road holding. No winding process for such non axi-symmetric profiles with integral-end dome winding has been developed so far. This innovation is intended for the filament winding of such tankers.
These composite tankers are more resistant to water and many chemicals. Their high strength-to-weight ratio and stiffness-to-weight ratio make them lighter and long lasting. They offer 45% weight saving over a steel tanker. The jointless winding of shell in an automated machine makes production faster and the product stronger. Two tankers can be made in a day vs. several days for steel. A factor of safety of six or above is guaranteed without any resin leakage.
In September 2008, the AMC approved the launching of the tanker for field application. Negotiations are in process with a major truck manufacturer in India for marketing the product with annual initial sales of 500 tankers.
