Guest Posted October 25, 2006 Report Share Posted October 25, 2006 Nowt wrong with glue, lotus elise's are glued together, not welded. I trust a good glue as much as i do a weld, especially in a carbon reinforced compostie, due to the layering.But the layering is within the tubing, what im saying is for example you have a CNC aluminium head tube, and rear brake area, like on kenny's prototype. The bond between the carbon tube and the aluminium is not going to be as good as a weld. While it may come close, because they are still two seperate materials, there is an inherent weakness surley? Welding bond's the two tubes or billet and tube in such a way that they are fused together.Your post give's me the impression you thought i was talking about the glue holding the differant layer's of fibre together rather than that bonding the tube's to other tube's/CNC area's etc....

F-Stop Junkie Posted October 25, 2006 Report Share Posted October 25, 2006 The big problem with carbon fibre is delamination. If you give carbon fibre a good whack the layers within the carbon will separate, but from the outside it will look fine. Give it a second whack and it will fail catastrophically with far less force than it would usually withstand. In the Canadian Grand Prix, Oliver Panis suffered two broken legs when he crashed. What left him injured, but where others have been protected, was the fact that he hit one concrete wall and the car deformed and then it turned and he hit a second concrete wall. The carbon had delaminated as it should for a crash structure and it left little protection for him on the second hit. What this means for a trials frame is that if you give the downtube a good whack and delamination occurs, then a much smaller knock or heavy landing could cause the downtube to collapse. Similarly scratches and so on will cause stress risers with massive potential for premature failure. For a carefully looked after frame, ridden by a good rider for specific events, then it's fine. For an everyday bike for an everyday rider, the think alloy or steel. Quote Link to comment Share on other sites More sharing options...
Guest Posted October 25, 2006 Report Share Posted October 25, 2006 I really think it's unlikely that we will see a full carbon frame, more likely to be carbon component's or like koxx carbon tubing for certain areas... Quote Link to comment Share on other sites More sharing options...
Jamie_Neal Posted October 25, 2006 Report Share Posted October 25, 2006 Scott are getting there. Carbon 7" full suss.If only they did trials bikes. Quote Link to comment Share on other sites More sharing options...
trialsking 55 Posted October 25, 2006 Report Share Posted October 25, 2006 my hockey stick is made from carbon fibre, but it is reinfored with something called aramid, which is very hard. it is an immensly strong stick. Quote Link to comment Share on other sites More sharing options...
Has anyone seen my shoe? Posted October 25, 2006 Report Share Posted October 25, 2006 (and show me a trials bike without scratches!!) Quote Link to comment Share on other sites More sharing options...
Ali C Posted October 25, 2006 Report Share Posted October 25, 2006 that a no count! Quote Link to comment Share on other sites More sharing options...
Has anyone seen my shoe? Posted October 25, 2006 Report Share Posted October 25, 2006 It does count, I even got a 26" just so you couldn't argue as much Quote Link to comment Share on other sites More sharing options...
skuzzbucket Posted October 25, 2006 Author Report Share Posted October 25, 2006 (edited) I have been in dicussions with a carbon specialist for F1 team.Going to look at the problems more in deapthand try to see if we can bring some thing a little special to the trial scene, but it wont be a full carbon frame or might it will see.
