Assessment of mechanical and three-body abrasive wear peculiarity of TiO2- and ZnO-filled bi-directional E-glass fibre-based polyester composites

Abstract

This paper is about the development of bi-directional E-glass fibre-based polyester composites filled with zinc oxide (ZnO) and titanium dioxide (TiO 2) fillers, respectively. The mechanical characterization of these composites is performed. The three-body abrasive wear characteristic of fabricated composites has been assessed under different operating conditions. For this, the three-body abrasion test is done on dry abrasion test rig (TR-50) and analysed using Taguchi's experimental design scheme and analysis of variance. The results obtained from these experiments are also validated against existing microscopic models of Ratner-Lancaster and Wang. A good linear relationship is obtained between specific wear rate and the reciprocal of ultimate strength and strain at tensile fracture of these composites. It indicates that the experimentally obtained results are in good agreement with these existing models. It is found that the tensile strength decreases with filler loading, while hardness, flexural strength, inter-laminar shear strength and impact strength are increased. TiO 2-filled composites were observed to perform better than ZnO-filled composites under abrasive wear situations. The wear mechanism is studied in correlation with the SEM micrograph of the worn-out surface of composites. Performance optimization of composites is done by using VIKOR method.

Cam Elyaf Takviyeli Polyester (CTP) Kompozit Malzemelerde Kullanılan Doğal Elyaflar ve Dolgu Maddeleri

“…Deneysel sonuçlarda; dolgu malzemelerinin ilavesi ile çekme mukavemetinin azaldığı fakat sertlik, eğilme mukavemeti, tabakalar arası kesme mukavemeti ve darbe mukavemeti gibi diğer mekanik özelliklerin arttığı görülmüştür. Diğer yandan TiO 2 dolgulu kompozitlerin ZnO dolgulu kompozitlere kıyasla daha iyi aşınma özellikleri sergilediği gözlemlenmiştir [56].…”

The Wear of Glass Fiber Reinforced Polyester Composite Materials at Different Loads and Speeds

“…It was seen that tensile strength decreased with filler, load, hardness and impact strength increased. TiO 2 coated composites showed better wear performance than ZnO coated composites [13]. The effects of different fiber reinforcements on the wear behavior were investigated in another study.…”

Investigation of adhesive wear properties of glass fiber reinforced polyester composites having different chemical compositions

“…In their study, it was observed that the addition of E-glass fibers increased the wear resistance and the mechanical properties of composite materials. Singh and Sıddhartha 10 investigated three-body abrasive wear and mechanical properties of TiO 2 - and ZnO-filled bi-directional E-glass fiber-based polyester composites. They observed that composite materials filled with TiO 2 had better wear properties than composite materials filled with ZnO.…”
