In this study, the effects of incorporating recycled photopolymer-plate residues from a packaging flexography process into polyester-glass fiber composites were examined. Ternary with an unsaturated polyester matrix elastomer particles evaluated using two types glass fibers: in forms fabric bidirectional fibers and blanket multidirectional fibers. The prepared by hand lay-up lamination differen...

An unsaturated polyester resin (UPR) mortar was applied to repair the damage tension zone's one-way reinforced concrete (RC) slabs. The load carrying capacity of patched RC slab is interest justify effectiveness repair. Yield Line Theory (YLT) may be used estimate slabs under concentrated load. results YLT are compared with experimental evaluate validity method. confirm that patching alters yie...

A composite materials were prepared using a polymeric blend of epoxy resin and unsaturated polyester as matrix material, nanoceramic powder Lead Zirconium Titanate reinforcement material in different adding ratios( 2wt % & 6wt ). Impact strength, surface hardness, thermal conductivity solutions absorption tests carried out for the samples. The pre-immersion results showed that ceramic to improv...

Self-reinforced poly(ethylene terephthalate) (PET) composites prepared by using a modified film-stacking technique were examined in this study. The starting materials included a high tenacity PET yarn (reinforcement) and a low melting temperature biodegradable polyester resin (matrix), both of which differ in their melting temperatures with a value of 56°C. This experiment produced composite sh...

Two original art installations constructed from unsaturated polyester resins (UPR) and four different reference UPR products (before and after UVB aging) were analyzed by high-resolution 1D and 2D nuclear magnetic resonance (NMR) spectroscopy. Breaking strain studies were also conducted for the four UPR model products before and after different aging procedures (moisture, UVB exposure, melt/fre...

In the present investigation, we successfully fabricate a hybrid polymer nanocomposite containing epoxy/polyester blend resin and graphene nanoplatelets (GNPs) by a novel technique. A high intensity ultrasonicator is used to obtain a homogeneous mixture of epoxy/polyester resin and graphene nanoplatelets. This mixture is then mixed with a hardener using a high-speed mechanical stirrer. The trap...
