"A team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has created a super-strong yet light structural metal with extremely high specific strength and modulus, or stiffness-to-weight ratio. The new metal is composed of magnesium infused with a dense and even dispersal of ceramic silicon carbide nanoparticles. It could be used to make lighter airplanes, spacecraft, and cars, helping to improve fuel efficiency, as well as in mobile electronics and biomedical devices." http://www.nanowerk.com/nanotechnolo...wsid=42203.php By next Christmas everyone will have donated their CF bicycles to the poor, and will be buying replacements made of this new alloy. Yup, it's going to take over like that foamed aluminium that Biomega built an ess-shaped bike frame with about ten, twelve years ago. Seriously, though: I used to know Frank Costin, the -cos in Marcos, the aerodynamicist of the early Lotus cars. He made a really good case for wood being the ideal material for car chasses, and the proof was in the pudding, the Marcos raced at Le Mans still casually parked in front of English pubs for years to come... I built a moulded wood 68ft racing yacht that survived a whole lotta hard journeys (back and forth across the Southern Ocean in midwinter, around Cape Horn, cruising the Indian Ocean out of Mombasa for several monsoon seasons, a superior four-seasons passage maker once its racing days were over). Wood is indeed a wonderful engineering material. But wood never took off for loadbearing car structures and except as a luxury item for millionaire racers, it is a dead issue even in yachts. As an aside rather than any kind of a big unit-number argument: Oddly enough, though the beautiful Renovo and other wood bikes are luxury items for rich eccentrics, wood may have a future in bicycles in the form of lashed-up bamboo bikes serving as cheap transport for the third world poor, vide Craig Coffee. That's not all. I can remember how slowly GRP (glass reinforced plastic, FRP to Americans) took off back in the days before carbon fibre, and how every little scare quite disproportionately set back the small gains its enthusiasts made. The question also arises whether the new material will have the ride qualities of steel -- or aluminum. Andre Jute To forget is to repeat the mistakes of the past |

Pure magnesium burns brilliantly if you use a match to light a thin ribbon of the stuff, in part because there's not enough mass present to conduct the heat away. Pure magnesium and some alloys can burn during machining if their chips get hot enough. But many alloys will self-extinguish, and large chunks conduct heat away quickly enough that it's hard to get them close to their ignition temperature. -- - Frank Krygowski |

I'm no expert but the account of a man who successfully burned a Next computer magnesium case is interesting. It was quite difficult to get going but spectacular once lit. http://simson.net/hacks/cubefire.html -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |
