Along with the development of automotive
technology in recent years, the search for alternative compositions for brake
pads has also increased. Composition is expected to be produced from
alternative dusts as well as performance of the many brake pads that contain
dust. In alternative dusts, being environmentally friendly and having low cost
are the most important factors. In this study borax tobacco and wollastonite
were used in our country with high reserves. Water and oil absorption behavior
of brake fluid samples produced with alternative dusts has been tested. The results obtained are compared
with commercial brake linings used as references. The hardness values of the
samples immersed in water decreased more than the samples immersed in the oil. Less hardness change was observed
in the samples using wollastonite as additive. The density values of the
borax-added brake pads are closer to the reference brake pad. The weight change
observed in the wollastonite-added brake pads was obtained at values close to
the commercial brake pads sample.

Organik Katkılı Fren Balatası Numunelerinin Su ve Yağ Emme Özelliklerinin Karakterizasyonu

Öz

Son yıllarda otomotiv
teknolojisinin gelişmesiyle birlikte, fren balatası için alternatif kompozisyon
arayışı da artmıştır. Kompozisyonunda birçok tozu barındıran fren balatalarının,
performansının yanında, alternatif tozlardan üretilmesi de beklenmektedir.
Alternatif tozlarda, çevre dostu olması ve maliyetinin düşük olması istenen en
önemli faktörlerdendir. Bu çalışmada, ülkemizde yüksek rezerve sahip boraks ve
wollastonite kullanılmıştır. Alternatif tozlarla üretilen fren balatası numunelerinin
su ve yağ emme davranışları test edilmiştir. Elde edilen sonuçlar referans
olarak kullanılan ticari fren balataları ile kıyaslanmıştır. Suda bekletilen
numunelerin sertlik değerleri, yağda bekletilen numunelere göre daha fazla
düşmüştür. Katkı maddesi olarak wollastonite kullanılan  numunelerde daha az sertlik değişimi gözlenmiştir.
Boraks katkılı fren balatalarının yoğunluk değerleri referans fren balatasına
daha yakın değerlerdedir. Wollastonite katkılı fren balatalarında gözlemlenen
ağırlık değişimi ise ticari fren balatası numunesine  yakın değerlerde elde edilmiştir.
