Dear technology enthusiasts,
This Monday and Tuesday (September 28th-29th) is being held in Chicago the 2nd Composites World Expo.
Dassault Systemes is of course well represented, with a booth and several speaking slots.
One of them, on Tuesday September 29th, is shared with the DS partner Intercim around the theme of Manufacturing Excellence for Composites.
We thought it would be interesting to look at what Intercim offers for Composite Manufacturers through a customer case.
In the wake of the all-new Boeing 787, the first airliner predominantly built from carbon composites, the entire industry is seeing a major shift of the demand.

To put things in perspective, let’s look at the market dynamics. The Industry is gradually transitioning from experimental and low volume productions to massive amounts .
The amount of carbon fibers consumed by the Industry is expected to double over the next 6 years. Are the manufacturers ready for that “bungee” jump?
Reducing costs of composite manufacturing processes while coping with production ramp-ups now becomes strategic. Let’s look at the case of EADS Composites Atlantic, and how difficult it can be to ramp up a composite production.
Wonder what it feels like not being able to deliver when the customer asks for more?
“In the fall of 2006, five years into a major contract for the biweekly delivery of ten types of products (leading edges, rudders...) to be used on aircraft manufacturing, we had slipped dangerously behind schedule in manufacturing and deliveries, up to 6 months late on one product in particular,” recalls Séverine Guitton, Head of Quality & Methods for Composites Atlantic Limited (CAL).
On the most heavily affected leading edge products, the scrap rate had reached 13% and rework hit 28%! However, there was absolutely no logic that could explain this highly irregular defect. All of the manufacturing parameters, constantly checked and rechecked, fit perfectly with the plans.
Once the INTERCIM solution for Composite Manufacturing (Pertinence Suite) was in place, workers began collecting 96 parameters at various stages of the production process, for each new part that was manufactured. The “Rule Discovery” module from INTERCIM, a patented technology, quickly identified two totally unrelated and until then unsuspected characteristics as directly influencing the recurrent defects. “Rules Discovery enabled us to clearly establish specific rules regarding key parameters, far from any known scientific explanation and most strikingly in total contradiction to all of our intuitions,” underlines Séverine Guitton. Then the workers receive conditional notifications in real time during the execution with the INTERCIM Operations Advisor module, live on the shop floor. “By applying these rules to our normal operating procedures, we immediately reduced the scrap rate from 13% to zero and rework came down from 28% to less than 1%,” she continues.

Does the Composites Atlantic example inspire you?
And what if that could apply to other industries as well?
