Abstract

Bu çalışmada, cam elyaf takviyeli epoksi kompozit
numunelerin darbe davranışı deneysel olarak incelenmiştir. Bu amaçla 100x100 mm
boyutlarında 8 tabakalı kompozit numuneler vakum infüzyon yöntemi kullanılarak
üretilmiştir. Numuneler, oda sıcaklığında güneş görmeyen kapalı bir kavanozdaki
hidroklorik asit çözeltisi (asit derişikliği %15 ve % 25) içinde, farklı
sürelerde bekletilmiştir. Darbe testleri Fractovis Plus darbe test cihazı
kullanılarak, iki farklı darbe enerjisinde (20J ve 30J) gerçekleştirilmiştir. Kuvvet
çökme eğrileri, darbe enerjisi-maksimum kuvvet eğrileri, darbe enerjisi, çökme
eğrileri, hız-zaman eğrileri ve kuvvet-zaman eğrileri çizilmiştir. Hidroklorik
asit çözeltisinde bekletilen numunelerden elde edilen deney sonuçları ile oda
sıcaklığında bekletilen numunelerden elde edilen sonuçlar karşılaştırılmıştır.
Deneysel çalışma sonucunda, asidik ortamın kompozit numunelerin yük taşıma
kapasitesini azalttığı fakat eğri tipini değiştirmediği görülmüştür.

Abstract

In this study, impact behaviors of glass fiber/epoxy composite plates
have been investigated, experimentally. 
For this purpose, composite samples have been manufactured in dimensions
of 100x100 mm and with layer of 8. The specimens kept into hydrochloric acid solutions
(acid concentration 15% and 25%)   in a
closed glass jar in sunless for different exposure times at room temperature. Impact tests were performed using Fractovis
Plus impact test machine at two different impact energies (20J and 30J). After
impact tests, force- deflection curves, impact energy- deflection,
velocity-time and force-time have been plotted. The experiments results
obtained from the specimens kept into hydrochloric acid
solutions were
compared with no immersed specimens. As a result of experimental studies, it
was seen the acidic environment reduced the load carrying capacity of composite
specimens but did not change the curve type.
