nanocomposite vulcunizates based on styrene-butadiene rubber (sbr), organoclay and a conventional sulfur curing system were prepared by melt blending process in an internal mixer. in order to study the effects of the type of interfacial compatibilizer on the properties of sbr and clay nanoparticles,three types of compatibilizers, maleic anhydride grafted ethylene-propylene diene rubber (epdm-g-...

The co-pyrolysis of various biomasses mixed with two types plastic waste was investigated in this study. Mixture M1 consisted 30% m/m styrene–butadiene rubber (SBR), 40% polyethylene terephthalate (PET), and polypropylene (PP). M2 PET, PP, acrylonitrile–butadiene–styrene copolymer (ABS). SBR, ABS, PP used study were from the automotive industry, while PET originated scrap bottles. Co-pyrolysis ...

An effort was made to improve the separation issue of styrene-butadiene-styrene modifiers in styrene-butadiene-styrene-modified asphalt binders and further enhance their performance by adding nano-ZnO binder prepare compound modified binder. First, optimum dosage determined based on conventional tests, i.e., penetration, ring ball softening point, ductility at a fixed dosage; then, dynamic shea...

The usage area of 3D printers from architecture to heavy industry has been increasing in recent decades. By this process, it is possible manufacture structures having different geometric configurations improve the mechanical, vibration, impact, and acoustic properties structures. In study, three-point test specimens with topologies were produced by printing method order see effect configuration...

The fabrication of robots and their embedded systems is challenging due to the complexity interacting components. integration additive manufacturing (AM) robotics has made advancements in through sophisticated state-of-the-art AM technologies materials. With emergence 3D printing, printing materials are also being considered engineered for specific applications. This study reviews different rob...

This presentation provides a brief overview of the production and use of 1,3-butadiene in the United States. Starting as a coproduct of ethylene, the 1,3-butadiene monomer is extracted and purified, then transferred to consumers. Major uses of 1,3-butadiene include the manufacture of styrene-butadiene rubber, polybutadiene rubber, and adiponitrile.

Composite filaments based on acrylonitrile butadiene styrene (ABS) consisting of cellulose nanocrystal (CNC) were prepared by melt intercalation using a single screw extruder. The effect CNC loading levels (0-4 wt%) the tensile properties and water absorption behavior was investigated in this work. Results indicated that composite exhibited rougher surfaces non-uniform diameters than neat ABS f...

Additive manufacturing techniques continue to develop and cover all industrial fields. However, the performances of aspect mechanical behavior parts obtained by this process remain be mastered are still subject current research works. Among these performances, one corresponding resistance propagation cracks. In order improve very interesting property in various fields, it is desirable master un...

This paper investigates the effects of layers orientation on impact energy absorbed by acrylonitrile butadiene styrene (ABS) test specimens, obtained additive manufacturing (AM), having three in-plane deposition directions (0°, 45°, and 90°). The specimens were tested with instrumented Charpy hammer, CEAST 9050 Pendulum Impact System, according to standard ISO179-1. Unnotched in edgewise direct...
