Type of carbon fiber
HMF Carbon fiber
HMF carbon fiber is used to maximize strength and to keep weight low. This material has an optimal blend of stiffness and strength that offers the best riding session. The know-how of SCOTT engineers is utilized in order to create the perfect lay-up with orientation and fiber size. HMF fiber will offer superior strengh compared to the industry standard.
HMF
Tensile Modulus: 125GPa
Tensile Strength 2450MPa
HMX Carbon fiber
SCOTT has improved upon the now conventional high modulus carbon fiber, HMF, used throughout the bicycle industry. HMX is a fiber blend used by SCOTT, and is 20 percent stiffer than its HMF counterpart for the same weight. This unique material allows SCOTT engineers to create incredibly light bikes with excellent riding characteristics. The cost of HMX, however, is three times that of HMF, and is therefore reserved for our high end Premium,Team Issue, and RC frames.
HMX
Tensile Modulus: 154GPa
Tensile Strength: 2950Mpa
HMX-SL
HMX-SL utilizes Nano-technology, which incorporates a carbon nanotube reinforced epoxy resin as well as T1000G carbon fiber. The carbon nanotubes offer an improved strength perpendicular and at off-axis to fiber direction, which allows for a better inter-laminar shear strength. The cohesion between the fibers is improved compared to our industry leading HMX carbon blend offering an unprecedented resistance. T1000G is the world's highest tensile strength fiber. This fiber is traditionally used for aerospace or defense applications. Strategic use of this new material results in a frame that is lightweight without compromise in power transfer.
WHAT IS THE DIFFERENCE
HMX filaments are both stiffer and smaller in diameter than those of HMF carbon. Because of this, an HMX frame can be built of tubes with thinner wall thicknesses to achieve the same stiffness of a corresponding HMF frame.
The final difference between a HMX and HMF frame is mainly the weight. A HMF frame is about 14% heavier than a HMX frame.
HMX-SL is 8.5% lighter on a full frame than HMX
HMX is 14% lighter on a full frame than HMF

carbon frame production process

This is a story about a carbon fiber SCOTT bicycle. Carbon is the ultimate source material for a high performance bicycle, but carbon is nothing without engineering. Every form, every detail in the layup is a tactical plan with an intended result.

Digital Design
and Development

DIGITAL DESIGN
and Development
SCOTT carbon frames are all designed, engineered and virtually tested prior to opening new molds. Concepts are first validated by our team of designers to ensure that they integrate with the overall SCOTT ethos. Our engineers then build a 3D model of the frame which can then be analyzed by the most advanced FEA and CFD industrial tools, as well as our own, in-house developed, kinematic and composite structure software. These tools allow our engineers to assess a frame's weight and volume, stress distribution, stiffness rating, aerodynamic performance, suspension characteristics with regard to kinematics and spring rates, and fiber ply layup schedules.
INITIAL MANUFACTURING
Once the virtual design and engineering process is completed, the first mold can be opened. SCOTT engineers layup the initial frame themselves. The resulting prototype frames then go directly from the mold to the test lab to assess frame strength and stiffness. The frame will then go through several cycles of layup refinement and testing until all performance targets are met.
FINAL PRODUCTION
Prior to mass production, a pilot run of frames is produced to validate all tooling and layup schedules. These pilot frames are then subjected to further lab testing, before being ridden in real world conditions. It is at this point that our professional teams and riders enter the equation, pushing the bikes to their limits and providing valuable feedback.
