Preparation and Characterization of Hollow Glass Microspheres- Reinforced Poly (acrylonitrile-co-butadiene-co-styrene) Composites

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. The results also indicated that addition of 5.0 wt.% of HGM along with 5.0 wt.% of powdery ABS at the central extruder zone maintains the HGM integrity while powdery ABS contributes to better filler dispersion in the matrix resulting in light-weight composites having improved mechanical properties.

Extrusion Based 3D Printing of Sustainable Biocomposites from Biocarbon and Poly(trimethylene terephthalate)

“…The PTT blend and its biocomposites were considered to be frequency dependent since the storage modulus and loss modulus value increases with increasing frequency. This has also been found in other composites [ 46 ].…”

“…The storage modulus defines the potential energy stored in the materials and thus describes its elastic response under deformation [ 46 ]. The PTT blend and its biocomposites were considered to be frequency dependent since the storage modulus and loss modulus value increases with increasing frequency.…”

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

“…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.…”

Improvement of insulation properties of glass fiber fabric/epoxy composites modified by polymeric and inorganic fillers

“…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.…”
