Due to significant environmental advantages, biocomposites have recently received increasing attention. In the present research, strength of hat-shaped coir fiber biocomposites tubes reinforced with nano powder was evaluated experimentally under 3-point bending tests. The tubes were manufactured using hand lay-up technique and based on Taguchi design of experiment. The effects of different para...

Improving the mechanical properties of epoxy-based adhesives with nanoparticles is one methods which justifies use adhesive joints significantly. This work studies strength adhesively bonded single-lap (SLJs) considering pure adhesive, reinforced nano-silica particles (NSPs), nano-clay (NCPs), and a combination both nano particles. Uniaxial tensile testing SLJs was conducted to reveal failure l...

background:  ramsar, a northern city in iran, lies on the coast of the caspian sea. this city has areas with some of the highest levels of natural radiation measured to date. the radon concentration in some areas of ramsar is up to 3700 bq m–3. on the other hand, due to high level of humidity, damp-proof barriers should be used in construction of new buildings in radon prone areas of this city....
