In this paper we investigated the direct-adhesion of Thermoplastic Polyurethane (TPU) to Acrylonitrile-Butadiene-Styrene (ABS). Specimens with an initial pre-crack were obtained by overmolding the TPU onto ABS substrates, at different melt and mold temperatures. The interfacial adhesion between these two dissimilar polymers, represented by the peeling force, was measured directly by using the standard T-peel test at room temperature and at a crosshead speed of 254 mm/min. The peeled fracture surfaces were observed under optical microscope to identify the failure mechanism (adhesive or cohesive). A qualitative correlation was established between the adhesion strength and the injection molding parameters.

The aim of this study is to evaluate the interfacial adhesion of Fused Deposition Model (FDM)-printed Acrylonitrile butadiene styrene (ABS) and Polylactic acid (PLA) bonded using commercially – available epoxy and elastomeric bonding agents. An adhesive was applied to the 3D printed specimen to quantify the interfacial resistance, the surface was then examined under an optical microscope in order to assess the reaction of the polymer to the adhesives. The results reported in the present work allow the conclusion of levels of bond improvement in the polymers.

In this study, electroless nickel (EN) plating on acrylonitrile butadiene styrene (ABS) engineering plastic using room temperature ionic liquids (RTIL) was studied. Electroless plating is a fundamental step in metal plating on plastic. This step makes the plastic conductive and makes it possible to a homogeneous and hard plating without using any hazardous and unfriendly chemical such as palladium, tin, etc. In the industry there are many distinct chemical materials both catalysts and activation solutions for the electroless bath which is one of the most important parts of the process. In this study the effects of the ionic liquid, plating time, and sand paper size were investigated on electroless nickel plating. The etching and the plating processes were performed with environmentally friendly chemicals instead of the chromic and sulphuric acids used in the traditional processes. Experiments were carried out with and without ionic liquid, EMIC, 1-ethyl-3-methyl imidazolium chloride (C6H11N2Cl), and with 400, 500 and 800 grit sandpaper with the application of the sand attrition process and 70, 80, and 90 °C bath temperatures with 30, 60, and 90 minutes of deposition time. The surface morphology and the thickness of deposit analysis were performed using the Fischer scope X-Ray XDL-B System, X-ray Diffraction (XRD), and Scanning Electron Microscopy (SEM). Due to the results of the experiments and analysis, the electroless nickel plating on ABS plastic was a success. The best plating was obtained at 5.010 μm as the maximum plating thickness, at 90 min of plating time and 80 °C as the plating bath temperature for electroless nickel plating on ABS plastic whit the surface activated with 800 grit sandpaper using EMIC ionic liquid.

Abstract A novel melt manipulation “RheoDrop” concept for hot runner injection molding is presented. In this concept, a controlled rotational shear is applied to a polymer melt in the hot drop to reduce its viscosity without raising the temperature. This is achieved by providing a transient rotational motion to the valve pin in the hot drop. This strategy is developed to mitigate issues associated with cold slug formation during injection molding in hot runner systems. The cold slug formation is particularly relevant for injection molding of engineering plastics such as liquid crystal polymers (LCPs) for medical and electronic applications. Analytical and experimental investigations were performed to validate the concept. The efficacy of the concept is assessed analytically utilizing a combination of two software modules, autodesk, moldflow and ansys fluent. The results confirmed that the concept was able to produce enough shear to reduce the dynamic viscosity between injection molding cycles. A prototype RheoDrop system was designed and developed and retrofitted in a four drop hot runner system mold to experimentally validate the concept. Preliminary experiments were performed utilizing acrylonitrile butadiene styrene, and parts were successfully fabricated at temperatures that are too low for traditional molding in a hot runner system.

Abstract In this study the tensile properties of additively manufactured Polylactic Acid (PLA), Acrylonitrile Butadiene Styrene (ABS) and Silicon Carbide (SiC) particulate filled PLA composites were assessed after aging for 4.5 months at 50°C in distilled water. The maximum moisture gain in PLA was about 16% by weight, and ABS gained 0.65%. In PLA/SiC composites, the weight gain due to moisture absorption was inversely proportional to the weight percentage of SiC loading. The PLA specimens degraded completely during aging without measurable residual strength. While the addition of SiC to PLA increased the room temperature tensile strength at lower volume fractions of SiC, the degradation of aged strength was similar to that of the pure PLA. The PLA/SiC composites had no measurable strength after aging. The ABS specimens retained their strength and failure strain after aging.

This paper presents the development of a new polymer matrix composite (PMC) feedstock material by the injection molding machine. The material consists of iron powder filled in an acrylonitrile butadiene styrene (ABS) and surfactant powder (binder) material. In this study, the effect of powder loading and binder content on the mechanical properties was investigated experimentally. The detailed formulations of compounding ratio by Brabender Mixer and injection molding machine of the sample specimen was used with various combinations of the new PMC material. Based on the result obtained, it was found that, higher powder loading of iron filler affected the hardness, tensile and flexural strength of PMC material. With 32% iron powder loading in ABS composites increase the flexural force, maximum stress and force of PMC material through an injection molding process.

The new wood-plastic nanocomposites (WPC) based on acrylonitrile-butadiene-styrene (ABS) resin was successfully blended with ABS and poplar flour (PF) through a HAAKE rheomix. The mechanical properties of nanocomposites, except for flexural modulus, were reduced after increasing the PF content. SEM photos show the reduction resulting from weak interfacial adhesion between the PF phase and ABS phase. Higher PF content leads to a low thermal stability and a high water absorption ratio. Different coupling agents (CA) were employed to improve the compatibility between PF and ABS. The results suggest that ABS-g-MAH is more effective than POE-g-MAH, EVA and SEBS. Maleic anhydride (MA) was blended in situ with PF and ABS as the reactive compatibilizer and mechanical properties of nanocomposites were improved except impact strength.
