Hasta La Ideas

It’ll take a bit of diligence, but I’m hoping to save up enough for my first custom bicycle next year. (I’ve acquired two bikes a year for the past two years and while I’ve been very happy with my collection thus far, I hope to go for quality over quantity from here on out.) As such, I’ve been following Prolly’s excellent documentation of his enviable new ride, a custom carbon road frame from Portland’s Argonaut Cycles (not pictured here).

However, I was also curious to see that a commenter mentioned another process for fabricating the material, carbon braiding, with a link to a new concept by designer Jacob Haim for Munich Composites.

Per the Munich Composites website:

Weaving is one of the oldest textile techniques at all. Alternately yarns over and under each other out and thus formed a braid. Converted textile looms have been used for the 80 years in research facilities for the processing of carbon fibers and developed. The braiding is now used in the series.

With the help of braiding the fibers are braided into a tube which stores closely to a shaping core. The fibers are then infiltrated in an injection process with resin and cured. The braiding technique offers the advantage of fully automating the fiber deposition. This minimizes the manual work previously required and possible sources of error are eliminated.

This manufacturing process was the subject of Haim’s thesis project for his degree in Applied Technology and Sciene from the University for Applied Sciences FH Joanneum – Graz. “The goal of this diploma work is a product range for high-end racing and casual bikes on the basis of a new frame technology, lug connections, special materials and high-end components.” As Haim told Bicycle Design:

His goal with the project was to challenge the way high-end composite bicycles are constructed today, and he went with a lugged construction that allows for a range of frames sizes (50cm to 60cm) using the same parts. Jacob points out a few of his reasons for the construction—”no material waste, low error rate, customized to the individual needs.” He also feels that it creates “a connection between high class engineering and the spirit of design.”

The young designer shared more information about the project via e-mail:
