The only complaints we heard were how much everyone missed the social side of being in the centre of Paris. It wasn’t so much fun being on the outskirts. You either stayed at an airport hotel to get to the exhibition quickly in the morning, or had a more pleasant stay, but braved the commute. We think that work and pleasure should be combined, so braved the commute, which wasn’t too difficult, even with the French strikes.
Modular, self-supporting, full composite bus body
This bus uses composite modules, which can be joined together, making it easier to produce buses of varying lengths. Simple, clever and using composites to their best advantage. We explained how much London relies on double decker buses rather than long buses (which get stuck around tight bends), so hopefully they will look at modules for taller buses too, it doesn’t hurt to ask...
Here are two pieces of technology that really impressed us and would be useful to a number of our customers:
Complex vacuum bagging of composites parts can be a bit of an art form, it’s the Marmite of the composites world, you love it or hate it and finding leaks is always time consuming. By using a network of vacuum connections and measuring flow rates at each, the software can estimate where a leak is, within 50mm. Once you fix one leak, the software then identifies the next until all leaks are found and fixed. At $45k US dollars, it’s expensive for most, but very cheap if you have high cost, complex parts or production critical timings then this kit could pay for itself in scrap reduction very quickly.
New to the composites market is this thin wire diamond wire saw from GTI. If you need to cut through fine materials such as thin laminates and honeycomb with chamfers, the cut and finish from this system was impressive. Although demonstrated attached to a robotic arm. If fitted to a tilting table, it can make manual honeycomb preparation really quick and easy with a nice neat cut line.
Lastly, to any of you new to composites you might want to contact Granta to have a look at their Composites design data software. It gives you access to materials data (allowing you to compare and select the most appropriate materials for your requirements), help answer material questions and improve communications.
