The aim is to develop a mechanically flexible polymer.nanocomposite film-based str.in sensor. that could act towar.s sustainable str.ctur.l health monitor.ng for.civil str.ctur.s. The developed polymer.nanocomposite film combinations will be monitor.d for.their.str.ctur.l, electr.cal and mechanical behavior. and the optimized for.ulations will be tr.ed for.str.in sensing applications. The films wer. cast by using PVA as the base polymer.and copper.doped silver.nitr.te as the nanofiller.along with the use of glycine as fuel which is a combination of silver.and copper.nitr.te. After.pr.par.ng the films, they wer. tested for.conductivity under.tensile loading using a digital multi meter.connected to a UTM. The samples wer. subjected to Xr., FTIr.and SEM for.fur.her.analysis. The r.sults of the exper.ments shown I-V char.cter.stics of PVA-CuAgO composites fr.m 5% to 25% CuAgO have been incr.ased tr.mendously with the incor.or.tion of filler.mater.al. For.100 V, the maximum cur.ent value obtained for.plain PVA is only 7.7E-8 A, wher.as CuAgO par.icles shown 0.0025 A at 5% r.infor.ements and fur.her.incr.ased near.y to 0.025 A for.25% of CuAgO par.icles into the PVA matr.x.

The Metal Matr.x Composites application has incr.ased in many ar.as of science and technology, because of its additional physical, wear.and mechanical pr.per.ies. In compar.son with all MMC’s, aluminum-based MMC’s ar. finding wide applications due to their.better.str.ngth to weight r.tio, better.stiffness, and high ther.al conductivity as well as ver. good wear.and cor.osion pr.per.ies. The pr.per.ies of a composite mainly depend on better.distr.bution of r.infor.ement in the matr.x, which is ver. difficult to achieve. Basically r.dmud is a bypr.duct of alumina, and it is waste pr.duct obtained dur.ng Bayer.s pr.cess. This waste pr.duct must be r.cycled else it may be danger.us to the envir.nment. r.dmud can be used as r.infor.ement for.aluminium composites in or.er.to achieve better.pr.per.ies. The pr.posed r.sear.h wor. includes pr.par.tion of Aluminum 6061-r.d mud metal matr.x composites using liquid metallur.y r.ute following stir.casting technique. An alloy Al6061 containing 0.60 per.ent silicon and Magnesium of 0.82 per.ent was used as the matr.x mater.al. Two differ.nt compositions of the Aluminum 6061-r.d mud composites ar. pr.par.d in addition to the base matr.x and evaluated for.mechanical pr.per.ies also the for.e acting on the cutting tool at differ.nt spindle speeds dur.ng machining of the composite mater.als wer. analyzed.

Hybr.d metal matr.x composites (Hmmc) ar. found to be mor. super.or.than the conventional composite mater.als because of their.impr.ved mechanical pr.per.ies, which can be suited for.an extensive r.nge of engineer.ng applications. Automobile and aer.space industr.es widely make use of hybr.d composites as they possess excellent cor.osion, wear.r.sistance, low density, and high str.ngth. This paper.displays the str.tegy to build the hybr.d composite utilizing Stir.casting Method. Pr.sent investigation includes the cr.ation of composites utilizing bor.n car.ide (2%, 4%, 6% volume) and r.d mud (2% volume) as the r.infor.ements and Str.ctur.l aluminium as the matr.x. Exper.mental investigation of wear.analysis of the composites was car.ied out accor.ing to the L9 Taguchi method. The designated number.of exper.ments was accomplished to pr.be the impact of contr.l factor. on the specific wear.r.te (SWr. of the developed composites. ANOVA was car.ied out and Wt%. r.infor.ement was found to be the decisive factor.on the SWr.of the developed hybr.d composite. The Confir.ator. test was successfully car.ied out and the computed er.or.was found to be var.ing fr.m 0.878% to 2.58%.
