Abstract:In this study, poly(acrylonitrile-co-butadiene-co-styrene)/hollow glass microspheres (ABS/HGM) composites were prepared by means of a twin-screw extruder. HGM were incorporated at different loadings of 2.5, 5.0, and 7.5 wt.% at the central extruder zone with different types of ABS. The morphological, physical, thermal, rheological and mechanical properties of ABS/HGM composites were investigated. Statistical analysis reveals that high impact ABS addition is significant for improving composites' impact strength… Show more

Three-dimensional (3D) printing manufactures intricate computer aided designs without time and resource spent for mold creation. The rapid growth of this industry has led to its extensive use in the automotive, biomedical, and electrical industries. In this work, biobased poly(trimethylene terephthalate) (PTT) blends were combined with pyrolyzed biomass to create sustainable and novel printing materials. The Miscanthus biocarbon (BC), generated from pyrolysis at 650 °C, was combined with an optimized PTT blend at 5 and 10 wt % to generate filaments for extrusion 3D printing. Samples were printed and analyzed according to their thermal, mechanical, and morphological properties. Although there were no significant differences seen in the mechanical properties between the two BC composites, the optimal quantity of BC was 5 wt % based upon dimensional stability, ease of printing, and surface finish. These printable materials show great promise for implementation into customizable, non-structural components in the electrical and automotive industries.

“…The literature studies examined show that GB are used in polyester composites between 0 and 10 wt%. 28,29 If the GB are used >10 wt%, the mixture becomes harder, the mixing time is extended and the production cost increases. In addition, GB can break during molding and damage the mold if used at high rates.…”
Glass fiber reinforced polyester composite materials are widely used in various areas due to their high specific strength, low weight, excellent elasticity, high corrosion resistance, and high thermal stability. This study aims to investigate the effects of resin materials and various fillers and wear parameters such as different loads and speeds on the tribological properties of glass fiber reinforced polyester composite materials. In this experimental study, various resins (tensile additive orthophthalic polyester and plain orthophthalic polyester), fillers (alumina and glass beads), and reinforcing materials were used during the sample preparation. The samples were subjected to an adhesive wear test at two different speeds ( n = 100 r/min and n = 200 r/min) and different loads ( F = 10 N and F = 20 N) at 150 m sliding distance. The friction coefficient and friction force were measured by the tribometer. The thickness of the wear trace was later measured and the wear rate was calculated. Wear surfaces of samples were visualized with a three-dimensional laser profilometer in order to obtain surface topographies and surface roughness values. The sample surfaces were examined by scanning electron microscopy in order to understand the wear mechanisms and to characterize the morphology of worn surfaces. Experimental results have shown that alumina or glass beads fillers can reduce the average friction coefficient when used in the correct amounts. The use of glass bead filler in orthophthalic polyester resin with tensile additive is more effective than reducing the wear rate compared to alumina filler. The load on the wear behavior of glass fiber reinforced polyester composite materials is more effective than the speed.
“…The inclusion of additives and fillers in polymer composite materials allows their use in a wide variety of applications. [41][42][43][44][45][46][47][48][49] Differently from the current literature, different fillers such as HGMs, PS microfiber membrane and PS solution have been included into glass fiber fabric epoxy composite in order to improve both sound absorption insulation and thermal insulation. PS is one of the most widely used materials in polymer industry due to its lightweight, low cost, and resistance against mechanical impacts.…”

“…[43][44][45][46] HGMs, also called bubbles or microbubbles, are generally used as reinforcing materials in a polymer matrix due its some desirable properties such as lightness, low-thermal conductivity, and low-dielectric constant due to its hollow structure. [47][48][49] As can be seen from above literatures, [35][36] nanofiber and microfiber membranes improve the sound absorption insulation properties of knitted fabric and nonwoven fabric structures due to decreased fiber diameter and increased specific surface area. [37,[40][41][42][43][44][45][46][47][48][49][50][51] On the otherhand, nanofiber and microfiber membrane have been used as a filler to improve the mechanical properties of fiber-based epoxy composite, as far as we know, it has not been investigated to improve the insulation properties of fiber-based epoxy composite.…”
Glass fiber fabric-reinforced epoxy composites (GEC) have some weakness on both thermal insulation and sound absorption insulation, which are very important for many application areas such as aircraft, train, and so on. The main aim of this study is to improve both sound absorbent and thermal insulation properties of GEC by incorporating different fillers such as hollow glass microspheres (HGMs), polystyrene (PS) microfiber membrane, and PS solution. Results show that incorporation of PS solution into glass fiber fabric epoxy composite (GEC-PS) provides higher sound absorption coefficient leading to an increase in the max SAC value from 0.1 to 0.4 and improvement in thermal insulation by decrease of thermal conductivity coefficient of GEC from 0.48 to 0.448 W/mK. Thermal insulation properties of GEC were improved by the use of PS microfiber membrane, which decreases the thermal conductivity coefficient of GEC from 0.48 to 0.438 W/mK. HGM did not improve both the thermal insulation and sound absorption insulation properties of GEC due to the agglomeration.
