Mechanical Properties and Sound Insulation Effect of ABS/Carbon-black Composites

Abstract

This article describes an evaluation of the mechanical properties and sound insulation effects of composites made of acrylonitrile butadiene styrene (ABS) and carbon-black using the design of experiment (DOE) approach. The solution blending process and method are presented. The effect of the acetone content in ABS during the drying process was studied by conducting tensile tests of injection-molded specimens. ABS was dissolved in acetone, and carbon-black was dispersed in the ABS/acetone mixture with varying conditions according to the orthogonal array table used to reduce similar experiments. The tensile specimens were produced by injection molding in each of the DOE cases, and the elastic modulus and maximum tensile strength of ABS/carbon-black composites were evaluated with a tensile test to determine the main effects of those factors. A sound insulation test was conducted with a modified impedance tube by using the DOE orthogonal array table, and a correlation between carbon-black and the sound insulation was revealed by a main effect analysis. An additional sound insulation test was conducted to verify the sound insulation effect of ABS/carbon-black composites as a function of the carbon-black percentage. The results indicate that the increase of carbon-black affected the mechanical properties as well as the sound insulation effects of ABS/carbon-black composite.

Sound transmission loss from polyvinyl acetate polymer mixed with different porous carbons

“…Materials like hollow microsphere, porous particle, foam and fiber are ideal for sound insulation applications [1]. A number of studies have been carried out to develop such soundproof materials namely gypsum board on concrete material [4], wood-waste tire rubber composite [5], inorganic particles/polymer composites, including CaCO 3 /polypropylene [1], hollow glass bead/polypropylene [6], carbon nanotube (CNT)/acrylonitrile-butadienestyrene [7], carbon black/acrylonitrile-butadiene-styrene [8]. All these studies suggest that the use of soundproof materials has a bright potential in controlling sound pollution problems.…”

“…However, there are few reports on the use of AC for acoustic sound insulation applications. On the other hand, carbon nanotube (CNT), a mesoporous material with a range of applications, has also been reported to have beneficial effects on increasing the performance of soundproof materials [7]. Hence, in this paper, we investigate the acoustic insulation properties of polyvinyl acetate (PVA) filled with microporous AC and mesoporous CNT, forming a composite soundproof coating.…”

Nanocomposites of Multiphase Polymer Blend Reinforced with Carbon Nanotubes: Processing and Characterization

“…Great number of twin-screw extrusion of major engineering polymer-based nanocomposites exists. High impact polystyrene (HIPS), [63] polypropylene (PP), [64][65][66][67][68][69][70][71] acrylonitrile-butadiene-styrene terpolymer (ABS), [8,[71][72][73][74] polyamide 6 (PA6) [75][76][77][78][79][80][81][82] or polycarbonates (PC) [5,56,[83][84][85][86] and polyurethanes (PUR) [87][88][89] are already widely investigated.…”

“…More materials are investigated, including: polystyrene/MWCNT, [63] poly(styrene-co-acrylonitrile)/MWCNT (SAN/MWCNT) [109] and finally to terpolymer-based nanocomposite poly(styrene-co-acrylonitrile-cobutadiene)/MWCNT (ABS/MWCNT). [8,[72][73]75] This brings the investigation to the desired point: PC/ABS-MWCNT nanocomposite [4,5] and PC/ABS as a final material. [74,150] Orientation of nanotubes in skin layer was found in samples processed with high injection speeds and reduced temperature, while the opposite sequence of parameters gave no alignment.…”

“…[73] Mechanical properties and sound insulating properties as a function of CB content is reported as well. [72] The number of publications regarding an industrial blend PC/ABS-MWCNT nanocomposite rapidly decreases to only few from the significant number of over 650 published in 2013. Despite the research groups working on this matrix, [150] the importance of this work is still minor at the moment.…”
