The previous winners of the German national Jugend forscht competition can also hold their own internationally, as was recently the case at the world's largest student competition, the 63rd Intel International Science and Engineering Fair (Intel Isef) in Pittsburg, Pennsylvania: the eleven-member German team presented a total of nine research projects to an international jury of experts from May 13 to 18. Philipp Peter (19) was one of the German prize winners selected by Intel Isef: with his computer-controlled fiber winding machine, he won NASA's 3rd prize worth 1,000 US dollars. He succeeded in proving that high-quality carbon tubes can also be produced on a simple computer-controlled fiber winding machine. He built a particularly smooth-running carriage from a light but rigid aluminum construction and some curtain sliders. This can wind the thread onto the core without jerking or disruptive tensile forces.
