Carbon fibre is the most used material currently to build high-level bikes. However, there are many varieties of carbon fibres. But even more important, the processing of these fibres makes the difference. And this is where an Italian carbon frame makes the difference in quality.
Carbon is a very resistant fibre, but the resin inside makes the composite product very strong. The resins that make the fibres work together. The great advantage of the composite material is that we can arrange the fibres in the direction that gives us the technically best results. But also to choose how to use the resins.
Custom Italian carbon frame
The pipes that we use in Daccordi are all built with special high-pressure moulds. The resins are injected under high pressure during the polymerization of the carbon. This operation allows a more excellent distribution of the resin among the fibres to make the structure more compact. At Daccordi, we only use superior quality carbon fibres produced by Italian companies, suppliers of the automotive and motorcycle companies of the Italian Motor Valley. The precious carbon leathers used by Daccordi are processed using high-precision cutting plotters. This also affects the final quality. In particular, the precision of the cut and moulds impacts the pipes’ structural resistance.
The tube-to-tube processing
The carbon tubes are cut, milled and mitred to form the frame, like steel, aluminium, or titanium tubes. After an initial treatment with two-component epoxy glues to give the shape and geometry to the frame, the junction points are worked by applying carbon fabrics pre-impregnated with resin and Kevlar, with a vacuum system in the absence of oxygen.
As a result, the wrapped frame has greater rigidity than the monocoque but at the same time, more excellent elasticity thanks to the presence of Kevlar. This greater elasticity translates into greater comfort and resistance to any impact. Furthermore, the tube-to-tube system is the only way to ensure that the material adapts to the physical and technical needs of the cyclist and not vice versa.
