This study focused on evaluating the mechanical, thermal, and morphological properties of polypropylene (PP) hybrid composites containing two different inorganic mineral fillers, namely wollastonite (WO) talc. The were prepared by melt mixing process using a twin screw extruder an injection molding machine. All contained constant filler loading at 20 wt% with varying WO/talc weight ratios (20/0...

Aims Three dimensional (3D) porous structures exhibit very good mechanical properties and an attractive strength-to-weight ratio. Because of their high load bearing capabilities and outstanding energy absorption properties in combination with their lightweight, they are excellent engineering materials, which are nowadays often used in automobiles and aircrafts [1-2]. Beside their dependency on ...

in this paper the influence of two different sizes of silica particles (micro-silica and nano-silica) was studied on mechanical properties of sulfur and sulfur composite. to improve the structural properties, sulfur was plasticized using dicyclopentadiene (dcpd) and methyl styrene (mst). plasticized sulfur composite was prepared by melt blending of plasticized sulfur and silica particles. the i...

A series of polystyrene hybrid nanocomposites have been fabricated with varying amounts of TiO2 viz., 0, 0.5 and 1 % w/w along with 3% TS by in-situ polymerization method. The influence of surface modified TiO2 nanoparticles on the thermal properties of PS matrix was examined using thermogravimetry and differential scanning calorimetry. Thermal characteristics of the polystyrene/TS/TiO2 hybrid ...

in this study, aluminum (al) matrix reinforced with micro-particles (30 µm) and nano-particles (50 nm) boron carbide (b4c) were used to prepare al-2.5%wt., b4c nano-composite and micro-composite, respectively, using mechanical alloying method. the mixed powders were mechanically milled at 5, 10, 15 and 20 hrs. the xrd results indicated that the crystallite sizes of both the micro-composite and ...

epoxy – polysulfide copolymers without or with low amounts of epoxy in their structure have poor mechanical properties in oxidative curing system.to strengthen the mechanical properties of polysulfide elastomer inclusion of epoxy resin (epon828) as hard segment was studied. ft-ir spectroscopy and rheometry were used to verify the formation of epoxy-polysulfide copolymer.  results obtained from ...

acrylonitrile butadiene rubber (nbr) composites are prepared from waste nylon 66 short fiber using a two-roll mill mixer. the effects of fiber content and bonding agent on the mechanical and morphological properties of the composites are studied. the curing characteristics of the composites have been studied by using cure rheometer. the cure and scorch time of the composites decrease while cure...
