1800’lü yılların sonlarında ortaya çıkan masa tenisi pek çok spor dalında olduğu gibi ekipmanların gelişimiyle
birlikte değişim ve gelişim göstermiştir. İlk zamanlarda parşömen kaplı uzun saplı raketler ile mantar veya kauçuk
toplarla oynanmıştır. 1930’larda sert kauçuk kaplı raketin icadıyla oyun değişmeye başlamış ve kompozit
malzemelerin yaygınlaşmasıyla masa tenisi raketi de değişmiştir. Ahşaptan üretilen raket tahtası tek katmandan
oluşabileceği gibi daha çok 3-7 katmandan oluşmaktadır. Raket tahtası ortalama olarak 17 cm uzunluğunda ve 15 cm
genişliğinde üretilmektedir. Ancak üretimlerinde şekil, boyut ve ağırlık yönüyle bir sınırlama olmadığından oyuncular
raket tahtalarını oyun tarzlarına göre seçmektedir. Uluslararası Masa Tenisi Federasyonu (ITTF) yönetmeliklerine
göre, raket tahtası kalınlığının en az %85'i ahşaptan oluşmalı ve yüzeyler düz-pürüzsüz ve sert olmalıdır. Darbe emilim
enerji değeri yüksek olan ağaç türleri masa tenisi raket tahtası üretimine daha uygundur. Raketin topa çarpma
anında oluşan vibro-akustik özellik ile raket tahtası arasında önemli bir ilişki bulunmaktadır. Masa tenisi raketi
üretiminde kullanılacak ahşap malzemenin uygunluğunun belirlenmesinde yoğunluk, çeşitli sertlik dirençleri, basınç
mukavemeti, eğilme direnci, darbe emilim enerjisi ve vibro-akustik özellikleri bilinmelidir. Üretiminde Hinoki,
Limba, Balsa, Kiri (Paulownia), Dişbudak, Ladin, Ihlamur, Ceviz gibi çeşitli ağaç türleri yaygın olarak
kullanılmaktadır.

Table Tennis Blade Production and Features

Öz

Table tennis, which emerged in the late 1800s, has changed and developed with equipment development,
as in many sports. In the early days, table tennis was played with parchment-covered long-handled rackets and cork
or rubber balls. The game started to change with the invention of the hard rubber-coated racket in the 1930s, and the
table tennis racket also changed with the spread of composite materials. A racket blade made of wood can consist of
a single layer, or it mostly consists of 3-7 layers. The racket blade is produced 17 cm long and 15 cm wide on average.
However, since there is no limitation in shape, size, and weight in their production, players choose racket blades
according to their playing style. According to the International Table Tennis Federation (ITTF) regulations, at least
85% of the racket blade thickness must be made of wood, and the surfaces must be smooth and hard. Wood species
with high impact absorption energy value are more suitable for table tennis blade production. There is an important
relationship between the vibro-acoustic feature when the racket hits the ball and the racket blade. Density, hardness
resistances, compressive strength, bending resistance, impact absorption energy, vibro-acoustic properties should be
known in determining the suitability of the wood material to be used in the production of table tennis rackets. Various
tree species such as Hinoki, Limba, Balsa, Kiri (Paulownia), Ash, Spruce, Linden, and Walnut are widely used in
racket blades production.
