Charpy impact response of glass fiber reinforced composite with nano graphene enhanced epoxy

Abstract

Fiber reinforced polymer composite materials show several superior properties over conventional engineering materials; on the other hand, most of composite materials also have some drawbacks such as brittle behavior of matrix. This study is aimed to improve the impact response of composite material by adding nano particle into epoxy matrix. For this purpose; an experimental study was conducted to investigate the effect of graphene nano particles inclusion in epoxy resin with glass fiber reinforced composite plate on the Charpy impact response. Glass fiber reinforced (GFR) epoxy composite plates were produced with various graphene nano platelets content such 0, 0.1, 0.25 and 0.5 wt%. Low velocity impact response was investigated by using Charpy impact test method. Impact energy and impact damage results presented in detail.

Buckling analysis of graphene nanoplatelets‐doped carbon/aramid hybrid polymer composite plates

“…On the other hand, the mechanical properties of the material improve up to a certain particle content, but after this point deterioration in mechanical properties occurs. [34,[49][50][51][52][53] Comparing the results for three boundary conditions reveals that the critical buckling load, as well as the buckling load-carrying capacity of the composite samples, decreases from fixed-fixed samples to free-free samples as expected. At each GNPs ratio, the critical buckling load took its minimum values when free-free boundary conditions were applied, and its maximum values when fixedfixed boundary conditions were applied.…”

“…Studies are generally aimed to improve the mechanical properties, impact resistance by enhancing the interfacial adhesion of fiber/matrix with nanoparticle fillers. 1–7…”

“…They assessed from the results that 0.5 wt.% NGPs decreased the viscosity of the resin and increased the heat for curing. Erklig et al 1 examined the Charpy impact behaviors of nano-graphene platelets filled notched and un-notched glass fiber-reinforced epoxy composites. They emphasized that 0.5 wt.% nano-graphene platelets filled GFR/epoxy composites exhibited higher energy absorption among all contents.…”

Low velocity impact and fracture characterization of SiO2 nanoparticles filled basalt fiber reinforced composite tubes

“…Adhesion between basalt fiber and epoxy matrix as can be understood from the obtained microscope views. 27,31,32,34,35,37,38 It was determined that the dominant failures in the impact damage regions were local delaminations and fiber breakages in the nanoparticle filled composite specimens and delamination and matrix crack failures were the dominant damages in the unfilled composite specimens just as observed in dominat failures in Charpy impact tests and the liquid penetrant inspections for nanoparticle filled and unfilled composites. Kara et al stated that delamination and debonding damage was reduced in filament winding composite tubes with MWCNT addition.…”

“…Many improvements have been made by filling into polymer matrix materials for the purpose of improvements of mechanical properties and fracture toughness of FRC in literature. 19,23,[28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44] In order to increase the fracture toughness and mechanical properties of basalt fiber-reinforced composites, the polymer matrix resin was modified with SiO 2 nanoparticles and multi-walled carbon nanotubes (MWCNT), nonoclay and graphene, etc. The best tensile and bending strength, impact energy, and fracture toughness values were obtained in connection with the homogeneous dispersion of nanoparticles in the polymer matrix at ther atios of 0.3-0.5% wt.…”
