Concept Development of Blades for Future Table Tennis Rackets : A Study of New Material and Design Solutions for STIGA Sports Table Tennis Range (English)
Abstract [en]

Historically, table tennis blades have been subject to few changes. Apart from the introduction of a few new materials, such as carbon fibre, resulting from rule changes in the sport, the pace of change has been slow. This project is based on three cases containing potential rule changes to the regulations of the sport regarding the construction of blades. Furthermore, the sport, its user’s needs, and potential new materials to implement have been investigated, resulting in the development of a series of prototypes. A total of 21 prototypes have been used with the aim of improving the control properties of the blade, which along with speed and spin are considered the most important playing characteristics in a table tennis stroke. The overall result from user tests indicates that three of the prototypes possess interesting properties which should be investigated further, out of which two are presented in this report. These prototypes consist of a prototype where a layer of the fibrous material Vectran is included, and a prototype where a layer consists of a honeycomb structure made of the material Nomex, and a third prototype that upon request from the company has been decided to be excluded from the report. Finally, recommendations for further development of these prototypes are described. 

Abstract [sv]

Stommar för bordtennisracketar är en produktkategori som historiskt sett genomgått små förändringar. Bortsett från att ett antal nya material, såsom kolfiber, introducerats till följd av olika regeländringar har förändringstakten varit långsam. Detta projekt har utgått från tre projektcase innehållande potentiella regelförändringar av bordtennisens regelverk avseende bordtennisstommens tillåtna konstruktion. Här har sporten, dess användarbehov samt potentiella nya material undersökts vilka prototyper tillverkats utefter. Sammanlagt har 21 prototyper tagits fram vilka främst avser förbättra racketstommens kontrollegenskaper, vilket tillsammans med fart och skruv anses vara de viktigaste spelegenskaperna hos racketen i slagmomentet. Det sammantagna resultatet från användartesterna visar att ett antal av prototyperna besitter intressanta spelegenskaper. Av dessa har tre valts ut vilka rekommenderas att undersökas vidare, varav två presenteras i denna rapport. Detta handlar om en stomme där ett lager av fibermaterialet Vectran används, en stomme där ett lager utgörs av en honeycombstruktur av Nomex, samt en tredje stomme som på företagets önskemål beslutats att ej inkluderas i rapporten. Till sist beskrivs rekommendationer för vidare arbete med dessa koncept.
