Yes, composites are very different. The whole process needs to be monitored more closely than just about anything else I can thing of. For example materials shipped or what ever must constantly be monitored. Temperature may not be so critical for finished composites, but epoxy can be ruined sitting on the shipping dock of a hot warehouse. An Engineer I once listened to that specialized in composite characteristic said simply it is just the opposite of concrete. For the most part accelerated aging etc must not be taken for real long term life characteristics. Each product must be sampled and tested through out it's life. I would not recommend making samples in the beginning because they will not experience what the actual product will. UV is important, the B-2 flys a lot at night and there are reasons for this. The way a composite product is treated will definitely help aging. The effort Boeing put into controlling in flight bumps should help. The B-787 will be watched very closely by Boeing, they have much to learn at this stage and procedures will get better with time and experience. Technologically I think those involved respect what they are facing, in the beginning this was not always so. Many people just did not know. It has taken us a life time to get this far, but those that are on the front lines of progress know how difficult it can be.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
