Fabrication and Characterization on Physico-Mechanical and Structural Properties of Sawdust Reinforced Acrylonitrile Butadiene Styrene (ABS) Composites

Abstract

The sawdust reinforced Acrylonitrile Butadiene Styrene (ABS) composites were prepared by using hot press molding machine for five different wt% (0%, 5%, 10%, 15% and 20%) at 180˚C temperature and 50 KN load. Sawdust was collected from local saw mill of Savar, Dhaka, Bangladesh and ABS polymer was collected from local market of Dhaka, Bangladesh. In this study, different properties of composites like physical (bulk density and water absorption), mechanical (tensile properties and hardness) and structural (Fourier Transform Infrared Spectroscopy) properties were studied. The bulk density of composites was not altered consistently and it gave greater value for 5% and 20% composites. The water absorption enhanced for all composites with the accumulation of fiber content and soaking time. The reduction of tensile strength and Leeb's rebound hardness of the composites were observed with the increase of the fiber content in all compositions. Maximum (%) of elongation was found for 5% composite, and then it gradually decreased; however, elastic modulus increased with the increased of fiber content in composites. Fourier Transform Infrared (FTIR) spectroscopy study was done for structural characterization. It was found that there was a new bond (C≡C) stretching formed for 20% composite; moreover, C-H rocking for 0% composite was broken for all other composites after the addition of sawdust in ABS polymer matrix.

Effect of Fiber Content and Silane Treatment on the Mechanical Properties of Recycled Acrylonitrile-Butadiene-Styrene Fiber Composites

“…Mechanical properties of NFPCs with ABS as the polymer matrix have been extensively investigated by various research groups across the world. Neher et al [2,37] examined the mechanical and physical properties of ABS/palm fiber composites and concluded that the tensile strength and flexural strength of the composite material decrease with the introduction of fiber content, but that the stiffness of the material increases. Similarly, Martins et al [38] observed that the introduction of fiber content considerably increases the stiffness of ABS/textile fiber composite materials.…”

Effect of fibre orientation and stacking sequence on properties of hybrid composites

“…The hardness of the composite is measured using an H-1000 portable hardness testing machine, as shown in Figure 5, according to ASTM A956-06 [9][10][11]. One of the four most commonly used techniques for metal hardness measurement is the Leeb Rebound Hardness Test [9,10,12], patented by the Swiss company Proceq SA. The conventional approaches are based on well-defined measurements of physical indentation hardness.…”

“…The elastic modulus of the composite varies with the increase in rice husk content, gradually increasing at first but showing a sudden decrease if the rice husk content reaches 10% [9]. Also, the water absorption of sawdust Acrylonitrile Butadiene Styrene (ABS) composite increases with the increase of soaking time and fibre content [10]. Hardness tests performed using the standard Leebs Hardness test showed a decrease in hardness with the increase in fibre content, a similar trend is noted for tensile strength [10,11].…”

ABS has also been used to generate other composites with natural fibres, such as palm fibre ABS composites [12].…”

Study of Viscoelastic Behavior and Mechanical Characteristics of Graphene-Filled ABS Composites

“…The alumina nanocomposites and carbon nanotubes with ABS improve hardness, Young'smodulus, tensile strength, and flexural modulus [5]- [6]. The rheological, thermal, and mechanical properties were studied, and it reported that 20wt% of Gr in ABS decreases melt flow index (MFI) and ABS+20wt% of Gr composites exhibited the highest heat capacity (0.84 J/g) [7]- [8].…”
