(Temporary thread derail... Oct. 24th) February 2010. Chris Carmichael is the well-known personal coach for seven-time Tour de France winner Lance Armstrong.
Carmichael commissioned artist, and cyclist, Kathleen King, to captute the entire 106-year history of the Tour de France on a 13' by 7' 11" canvas. It's an interesting story (originally appearing in www.triplecrankset.com) and written by "Lenny B". "It is often said that art imitates life. If that is the case, then artists need not look any further than the sport of cycling for their inspiration as it encapsulates the full spectrum of life’s travails and emotions (and sometimes in less than an hour).
Technical Articles. Carbon Technology | Carbon Durability Carbon Technology In an effort to help you cut through the smoke and mirrors and preponderance of gobbledygook, we have decided to prepare for you a no-nonsense primer on carbon technology.
We’ve noticed that there is a lot of hype about certain products, and a lot of claims of superiority in one way or another. Static.rcgroups.com/forums/attachments/1/0/7/6/2/a1159833-118-30012007069. Joe Harmon Design-Bladder Molding. Composite engineering - Bladder Molding Advice. I am currently involved in an effort to develop new molds for bladder molded tubular products and I am looking for some advice on tooling and process design.
I have experience and a reasonable understanding (I think) of autoclave molding, film infusion, as well as the liquid molding technologies however the bladder molding is new to me.We have done some preliminary development work using molds which were given to us and so far the results have been wanting. Closed-Mold Vacuum Infusion with a Bladder. I am still up for suggestions for a shorter name for this process, but, here goes- over the last few months i have been working on an idea to combine 2 composites production techniques: vacuum infusion, and bladder molding. i have had limited success, stay tuned for pictures, those will tell the story much better than this explanation, but here goes. most of you probably get the idea just from the title, but hopefully this will help light the way and clarify things for those who are curious. like i said, the pictures will light the way, shortly after this post. install vacuum retainer o-rings around cavity of bottom mold. gently close the mold lowering the top half onto the bottom half, peak into the edges to make sure you arent pinching any fiberglass or bladder between the flanges. bolt mold halves together firmly. install vacuum and resin supply lines into mold, sealing all ports with vacuum tape. install resin trap, hookup to vacuum source. clamp off resin feed line.

Build-to-print: Done Better. It’s hard to measure the transforming effect that unmanned aerial vehicles (UAVs) have had on modern warfare and security activities.
Growing demand for these “drones” — for surveillance, aerial photographs and attack duties — has led to a phenomenal proliferation of composites-intensive designs and concepts from a global supplier base. One of the many players in the U.S. UAV market is Insitu Inc. (Bingen, Wash., a subsidiary of Boeing Integrated Defense Systems Military Aircraft), which, with Boeing, developed the small (10-ft/3m wingspan) and successful ScanEagle Small Tactical Unmanned Aircraft System (UAS) for intelligence, surveillance and reconnaissance (see “Learn More,” p. 37). First flown in 2002, the ScanEagle has logged more than 10,000 combat hours and is considered an important tool for U.S. Because ScanEagle systems are in demand, Insitu works with a number of subcontractors to meet rate production. Scanning the project parameters Designing the production process.
Why Carbon Races Wheels? A Geeks Guide To Your Number One Aero Advantage. Carbon by Design - Carbon Fiber Design & Aerospace Manufacturing. Animation of the bladder molding process.
To build hollow parts it is often necessary to build an inflatable bladder which temporarily occupies the void within the part. We have designed several high pressure bladder systems for thin walled, hollow 3D structures. Our molds are typically created from aluminum molds with a minimum wall thickness of three inches.
Molds are la id up, joined, placed in a safety cage, and then inflated to anywhere between 50-175psi. At these pressures mold integrity and epoxy viscosity play a key factor. Please contact us with your engineering challenge or next tooling project. Commonly used in these applications: Hollow Tubes/Ducting Any Hollow Structure. Carbon Fiber Tubes - Learn How Carbon Fiber Tubes Are Made. Carbon fiber tubes are ideal for both the hobbyist and industry professional.
Using the rigidity of the carbon fibers, an extremely stiff yet lightweight tubular structure can be used in a wide range of applications. Carbon fiber tubes can replace steel, but more often then not, it is replacing aluminum. In many instances, a carbon fiber tube can weigh 1/3rd of an aluminum tube and still have the same or better strength characteristics. Because of this, carbon fiber reinforced tubes are often found in applications light weight is crucial, like aerospace, race cars, and recreational sports. The most common carbon fiber tubular profile shapes are squares, rectangles, and circular. Composites Manufacturing Magazine and Blog. F1 wishbone construction, a closer look - Forum. Another part under the spot light, rear lower wishbone.
In this thread over the next while Ill be unlocking a few secrets hidden within this part. Mainly, its construction, and how it was made. I will be cutting sections from it, and carrying out some destructive testing so anyone who is nervous, or cannot bare to see this sort of stuff cut up then leave now, its not the thread for you, if you have a keen interest, then this is the thread for you. To my knowledge, this is the first time this will be done in the public domain.I do not work in any F1 company, and have bought these parts legally, with my own money.I have read all disclaimers in reference to second hand F1 parts and what I am undertaking is legal.I am not going to mention the makers name all the same, just Incase Ive missed some small print.
