Effect of betelnut fibres treatment and contact conditions on adhesive wear and frictional performance of polyester composites

Nirmal, Umar and Yousif, B. F. and Rilling, Dirk and Brevern, P. V. (2010) Effect of betelnut fibres treatment and contact conditions on adhesive wear and frictional performance of polyester composites. Wear, 268 (11-12). pp. 1354-1370. ISSN 0043-1648


The current work is an attempt to use treated betelnut fibres (in mat form) as reinforcement in polyester
composites. The fibres were obtained from Alor Star in the state of Kedah, Malaysia. Wear and frictional
characteristics of T-BFRP composite were investigated against polished stainless steel counterface under
dry/wet contact conditions using a BOD machine. The tests were conducted at 2.8 m/s sliding velocity,
different applied loads (5–200 N) and sliding distances (0–6.72 km). Different orientation of the fibre mats
with respect to the sliding direction of the counterface was considered; anti-parallel (AP), parallel (P) and
normal (N). The worn surface morphology was studied using a scanning electron microscope (SEM). An
optical microscope was used to observe the wear track surface on the counterface, and the modifications
on the counterface roughness were studied. This work revealed that the wear and frictional performance
of the composite were enhanced under wet contact conditions by about 54% and 95% compared to the
dry. Specific wear rate under wet test for AP-O (2.5±0.01×10−8), and P-O (2.3±0.01×10−8), was low
compared to the dry test (AP-O: 5.1±0.01×10−8; P-O: 15±0.5×10−8). The composite exhibited high
wear performance in AP-O compared to P-O followed by N-O under both dry/wet contact conditions
