C-PLY(TM) used for the first time in a "live" demonstration at the K 2013 show
CHOMARAT, which specializes in textile reinforcements for composites, is an active participant in the "RTM in mold Coatings" project thanks to its line of spread NCF carbon reinforcements
For the first time, a carbon roof panel for the Roding roadster is made in real time, and mass produced, at the K'2013 show. This innovative project is the birthchild of a partnership between major players in the composites field, under the leadership of KraussMaffei*.
This latest technological advancement in an RTM process using a PU system with short cycle times makes it possible to produce composite parts with an excellent surface quality directly out of the mold. Indeed, the challenge of this process is to obtain, with the same tooling, a surface appearance that is compatible with both a visible carbon design and a surface quality allowing class A paints without any preliminary preparation or subsequent retouching.
The use of C-PLY(TM) Spread as a reinforcement contributes to the success of this project. C-PLY(TM) is a line of NCF carbon reinforcements developed by means of the latest fiber spread technologies. The line provides perfectly flat and homogeneous thin layers which limit the occurrence of microcracks. Its special construction gives it the necessary flexibility to make it readily deformable, and allows good positioning in the mold while still maintaining good permeability for RTM injection.
In addition to its visual qualities, the use of C-PLY(TM) SP reduces the cost and weight of composite parts while optimizing performance.
Live demonstrations will take place at KraussMaffei Hall 15, B27/C24/C27/D24 during the K'2013 Show from October 16 to 23, in Düsseldorf.

So steigert Predictive Maintenance die Produktivität
Die Produktionshallen von Großunternehmen sind nicht selten mit Anlagen und Maschinen im Wert von mehreren Millionen Euro gefüllt – Investitionen, die durchaus als strategische Erfolgsfaktoren zählen. Damit sich diese im vollem Umfang auszahlen, ist es entscheidend, Stillstandzeiten zu vermeiden, denn nur eine arbeitende Anlage ist produktiv. Um dies zu gewährleisten gewinnt Predictive Maintenance, die vorausschauende Wartung, immer weiter an Bedeutung.Weiterlesen
