REBOUND AND DAMPING BEHAVIOUR OF CARBON-FIBRE-REINFORCED POLYMERS
Xenia’s aim in this study is to provide the Footwear industry a guideline for the development of carbon-fibre-reinforced injected specimens, in particular inserts and soles, in such a way as to optimise performance of the final article in its intended purpose, be it walking, running, skiing, cycling, racquet sports and so on.
In detail, you can discover how Xenia have applied their expertise in carbon-fibre reinforcement technology to the Footwear industry, analysing the rebound and damping behaviour for a wide range of Xenia thermoplastic speciality compounds.
REBOUND AND DAMPING BEHAVIOUR OF CARBON-FIBRE-REINFORCED POLYMERS: GUIDELINES FOR THE DEVELOPMENT OF INJECTION-MOULDED PLATES
PRESENTATIONPREVIEW
The presentation explores in detail the following themes:
• Fine-tuning rebound and damping characteristics of the composites for each application
Material selection for any sporting application centres on a range of physical properties such as stiffness, breaking stress and strain, impact resistance, elastic-return velocity (rebound), vibrational-damping capacity and the variation of stiffness as a function of temperature. In this study we concentrate on the last three of these material characteristics.
• Introducing a new ranking system to help select the correct material for every application
Measurement of the elastic-return velocities and damping coefficients reveal well-defined behaviours according to the polymer bases used as well as the type and amount of reinforcing fibres employed in each compound.
• Discussion of the advantages of using thermoplastic polymer composites
Through examination of how material stiffnesses vary as a function of temperature for a series of polymers reinforced with 30% carbon fibre, we demonstrate how, by judicious choice of fibre and matrix, it is possible to design materials with the desired rebound and damping characteristics for specific applications.
