Abstract Red brick waste (RBW) powder was used as a reinforcing filler for acrylonitrile butadiene rubber (NBR) preparing eco-friendly composites. The main constituent of this is silica which considered to be one the traditional fillers in industry. So it worthwhile get suitable manner by using NBR. Physicomechanical properties were evaluated, including tensile strength, elongation at break, ha...

In this study, ornamental cranberry (Cornus Alba) reinforced hybrid composite is synthesized. The plant leaves have been collected, dried, and ground for production. After it into unsaturated polyester (UP) at different rates by mass, mixed to show a homogeneous distribution. Then, 5 wt.% of the total mixture added epoxy resin polymerization reactions are started with help necessary additives c...

This study investigate the Epoxy performance after reinforcing with Jute fibers. Before reinforcement process, natural jute fibers were immersed in three different concentrations of acetic acid (1%, 5%,10%) for one hour, then epoxy composites made from these treated a way that weight fraction is 30% also other samples composite but untreated Upon making reinforced composites, mechanical propert...

This article contributes to the development of new class fully biodegradable “green” composites by combining fibers (natural/bio) with resin. The vegetable (Triumfetta cordifolia and sugarcane bagasse) treated NaOH bleached were incorporated into a natural rubber matrix. influence fiber ratio on physical properties, tensile strength surface hardness hybrid was analyzed. results show that additi...

Abstract Few works had systematically investigated the relationship between rupture stress of oxide shell and diameter liquid metal nanoparticles (LMNPs). Here, we fabricated a series elastomer/LMNPs composites, which were based on various polyurethanes with different shore hardness LMNPs diameters, to study LMNPs. We established reliable guidable stress–strain curves elastomers diameters by bo...

The intertidal snail Littorina saxatilis has repeatedly evolved two parallel ecotypes assumed to be wave adapted and predatory shore crab adapted, but the magnitude and targets of predator-driven selection are unknown. In Spain, a small, wave ecotype with a large aperture from the lower shore and a large, thick-shelled crab ecotype from the upper shore meet in the mid-shore and show partial siz...

Agricultural residues such as Maize Husk, Groundnut Shell, Coconut Shell and Sugarcane Bagasse were collected, sorted, dried ground to particulate fillers. The various fillers characterized in terms of density, moisture content pH value. Single ordinates 150 µm particle size 30 parts per hundred rubber (pphr) loading respectively adopted for all filler types. They used alongside with convention...

Silicone is already widely used in biomedical applications thanks to its outstanding properties. Now additive manufacturing (AM) of silicone can achieve submillimeter details and offered by SpectroPlast AG as a service. AM particularly interesting for designs with complex internal structures such bioreactors or oxygenators where oxygen permeability important. Therefore, the additively manufactu...

Abstract A novel low-cost polyurethane (PU) elastomeric material reinforced with mat-form fiberglass for alternative ship was developed. The hand lay-up technique used to prepare samples glass fiber contents of 0, 7, 9, 11, and 15% by weight. Several tests, including density, tensile, hardness have been conducted investigate the effect content on properties developed materials. test results fou...
