NTPT develops with Richard Mille new quartz fibre prepreg material for watch Rafael Nadal.

North Thin Ply Technology (NTPT) is proud to be the supplier of the composite materials used in the new Richard Mille RM 27-02 Rafael Nadal watch. When the Spanish tennis player started his campaign to win a record tenth Roland Garros title, he was wearing the new watch of which the ultralight and unbreakable case has been made of Thin Ply Technology® (TPT®) Carbon and Quartz prepreg materials.

NTPT’s and Richard Mille’s engineers together developed a highly original prepreg and laminate material known as TPT® Quartz, composed of hundreds of layers of quartz filaments sequenced on top of each other. Quartz fibres are exceptionally resistant to high temperatures and are characterized by extreme strength and transparency to electromagnetic waves. To match these high technical specifications, NTPT developed a unique white, UV resistant matrix resin material.

For the Richard Mille RM 27-02 Rafael Nadal watch, NTPT started with producing rolls of UD prepreg tapes of carbon and quartz. These UD Tapes were then transformed into preforms with the assistance of NTPT’s Automated Tape Laydown (ATL) machine. The TPT® Carbon and TPT® Quartz preforms were then carefully stacked to create a black and white block and finally machined by Richard Mille to create the parts for the watch. The bezel and solid case back in TPT® Carbon/TPT® Quartz are attached to the unibody baseplate, a very complex part that has been machined from a separate 100% TPT® Carbon block.
