Acrylonitrile-butadiene-Styrene (abs), with and without calcium carbonate (calcite) particles,was used as the matrix for reinforcement with as-received short-glass fibres (were originallytreated by the manufacturer) and sized short-glass fibres with two amino-silane coupling *** calcite particle content is 0, 11.7 and 23.5 vol. pct for the matrices. The glass fiber contentis 0, 10 and 15 vol. pct. The matrix materials and corresponding composites were compoundedusing a twin screw extruder and dumbbell-shaped tensile bars were prepared with an injectionmolding process. The tensile and flexural properties as well as the unnotched and notchedCharpy impact energies of short glass fibre/calcite/abs composites were studied in this *** effects of fibres, fibre surface treatments and particles on these mechanical properties ofthe composites were discussed in detail. An importarit information was obtained, which is thatthe tensile and flexural strengths of hybrid SGF/calcite/abs composites are the same as thoseof corresponding fibre composites when the ratio of the interfacial adhesion strength betweenparticles and matrix to that between fibres and matrix is higher than certain value. otherwise theformer are lower than the latter.

The preparation technology of flame-retardant PC/abs alloys was studied in this paper. Using a high-efficiency flame retardant system and by means of multiple-ingredient compatibilizing, PC/abs alloys with excellent impact strength and flame retardant property were prepared. The experimental results showed that by using PS-g-MAH and SMA as synergistic compatibilizers, the notched Izod impact strength and flammability of PC/abs alloy obtained in the present work can be up to 175 J/m and UL-94 VO, respectively.

The paper discusses the mechanical and thermal performance manifested in natural nanorods attapulgite(ATP)reinforced Acrylonitrile butadiene styrene(abs)nanocomposites in the process of fused deposition modeling(FDM).Molten extrusion technique was taken to manufacture the filaments of abs/organic-attapulgite(OAT)nanocomposites with different mass fraction and the printing operation was made by one commercial FDM three-dimensional(3D)*** indicate that the mechanical performance of these FDM 3D printed specimens are improved obviously via the introduction of OAT,and tensile strength of the abs/OAT nanocomposites parts with only 2 wt%OAT addition is enhanced by 48.1%.At the same time,the addition OAT can reduce the linear expansion coefficient and creep flexibility,and improve the thermal stability and dimensional accuracy of these FDM 3D printed parts.

A novel technique for preparing functionally gradient electrically conductive polymeric composites was developed by using of solution casting technique on the principle of Stokes＇ law. Acrylonitrile- butadiene-styrene/Cu （abs/Cu） gradient polymeric composites were prepared successfully using this technique. The gradient structures, electrically conductive performance and mechanical properties of the abs/Cu composites were investigated. Optical microscope observation shows that the gradient distribution of Cu particles in abs matrix was formed along their thickness-direction. The electrically conductive testing results indicate that the order of magnitude of surface resistivity was kept in 10^15 Ω at abs rich side, while that declined to 10^5 Ω at Cu particles rich side, and the percolation threshold was in the range of 2.82 vo1%- 4.74 vol% Cu content at Cu particles rich side. Mechanical test shows that the tensile strength reduced insignificantly as the content of Cu increases owing to the gradient distribution.

This article provides a review of the research unde rt aken in order to determine the suitability of utilizing microwave technology in the production of Recycled abs Acrylonitrile Butadiene Styrene resin for mouldin gs. The experimental investigation determined the suitability of the existing re cycled abs material, the mould material used with respect to performance and lon gevity, potential commercial plant and equipment, end mould compression. Introduction Frequency Characterization of abs The first step in microwave processing of any material is to locate a frequency band suitable for the mateiial, where it absorbs microwave energy readily. To lo cate this band width, the abs material was characterized in Variable Frequency M icrowave Ovens operating between the frequenc’y ranges of 2.5 GHz to 6.5 GHz an d 6 GHz to 18 GHz. The variable frequency microwave oven records forward and ref lected powers over regular intervals in the swept frequency range and enables ca lculation of Re flec tan ce=Re fla tan ce forwrd PowerForward Power (1) A low reflectance indicates that the material Forward Power absorbs rela tively higher amount of incident microwave energy. Characterization of the PBS material showed clearly that a frequancy Fig.1 Lower frequency range vs. reflectance of abs at room te mperatureFig.2 Lower frequency range vs. reflectance of AB S at 80 ℃ 2.5 to 3.5 GHz is the most suitable frequency fo r heating the material. Other alternate frequencies are 12.25 GHz and 15 GHz. Fi g.1. Hazards When abs is melted a dark fume is omitted, exhaust system was applied, in order to mechanically ventilate and control exposure levels below air borne exposures. The product contains a trace quantity of acrylonitrile, a substance classified by Worksafe Australia as a Category 2 Carcinogen.
