The influence of the natural Gongura roselle fiber on tensile and flexural properties as well Shore D hardness acrylonitrile-butadiene-styrene (ABS) poly (lactic acid) (PLA) was investigated. composites were printed in fused deposition modeling (FDM) 3D technique. addition improved mechanical tested composites, while strength, modulus better case ABS-based composite. Whereas, PLA-based showed h...

New thermoplastic segmented polyurethanes were obtained by a one-step melt polyaddition using 40, 50 and 60 mol% poly(hexane-1,6-diyl carbonate) diol of [Formula: see text] g mol-1, 1,1'-methanediylbis(4-isocyanatobenzene) and 2,2'-[sulfanediylbis(benzene-1,4-diyloxy)]diethanol, 2,2'-[oxybis(benzene-1,4-diylsulfanediyl)]diethanol or 2,2'-[sulfanediylbis(benzene-1,4-diylsulfanediyl)]diethanol as...

BACKGROUND AND OBJECTIVE Chemical cleansing by denture cleansers is first choice for denture plaque control. The most common problems while using denture cleansers are hardening, porosity, odor sorption, water sorption, solubility, and colour change, bacterial and fungal growth. Chemical cleansing procedures have been found to have an effect on the physical and mechanical properties of denture ...

Abstract Bipolar plates are one of the most important components polymer membrane fuel cells. In this manuscript, rubber pad forming aluminum bipolar with Archimedes' screw-shaped channels and draft angle 90 $$^\circ$$ ∘ has been investigated. Hence, all possible combinatio...

Halloysite nanotubes (HNTs) were incorporated into an EPDM/SBR rubber/styrene-butadiene rubber (SBR) composite by melt blending of HNTs the blend. The mechanical properties, abrasion and swelling resistance ranging from 2 parts per hundred (phr) to 10 investigated in base rubber. Tensile strength, 100% modulus (modulus at elongation), elongation break tear strength evaluated ambient temperature...

The non-biodegradable polymer occupying the world leads to many issues concerning global warming and other related problems. Due these issues, there is a need for biodegradable polymers overcome issues. This paper focussed on processing polyvinylalcohol (PVA) crosslinked with glutaraldehyde(GA) studying harness of polymer. from 0 40 volume percent glutaraldehyde than post cured immersed in 2 mo...

The purpose of this contribution is to investigate different mechanical properties various types rubber composite materials that were filled with carbon black nanofiller. composites produced from three basic rubbers. Moreover, the volume concentrations rubbers including their ratios. Mechanical tested investigated by means tensile testing, Shore hardness, rebound resilience, friction, abrasion,...
