The Investigation i11to Tribological Properties of Carbon Fiber Reinforced Composite

Carbon fiber reinforced composites can be considered as a good candidate material
for tribological applications because of tbeir complex interwoven nature of the fiber
that makes it difficult to break. Since this advanced composite are relatively new in
tribological applications, studies need to be done to discover its friction and wear
properties. The main purpose of doing this research is to investigate the friction and
wear properties of carbon fiber reinforced composite. The samples of this composite
were prepared from carbon fiber prepreg. Tests have been conducted to evaluate the
friction and wear behaviour of the composite. The first test conducted was the
hardness test using an Indentec 9150 LKV hardness testing machine. Wear tests were
conducted using a TABER® 5131 Abraser. The purpose of doing this test was to
evaluate the resistance of surface to abrasive wear. Before and after the test, the
surface roughness of the composite was measured using a Perthometer Concept. The
adhesive wear mode of the composite was also tested by using a Ducom®
Multispecimen Tester. Finally, the studies on worn surface topography were done
using a Scanning Electron Microscope (SEM) to understand its wear mechanisms.
Based on the results obtained, the woven reinforcement composite proved to be better
in performance for both abrasive and adhesive wear.
