Comparison of the Experimental Mechanical Properties and DMA Measurement of Nanoclay Hybrid Composites

Abstract

This study explores the effects of nanoclay addition on mechanical response of Glass/Carbon/Glass fiber (G/C/G) reinforced epoxy matrix composite laminates under tensile and flexural loadings. Organomodified nanoclay containing Glass/Carbon/Glass hybrid composite laminate was evaluated for dynamic mechanical properties as well as mechanical strength, stiffness and ductility. Three different weight fractions of nanoclay containing fiber reinforced hybrid composites were manufactured. The amount of nanoclay additions were 0 wt %, 0.75 wt % and 1.25 wt % with respect to epoxy resin and hardener. A nanoclay containing epoxy-Glass/Carbon/Glass hybrid composite laminate were manufactured by using a hydraulic hot press. Then, tensile, flexural tests and dynamic mechanic analysis (DMA) was implemented to ASTM standard specimens which were cut from the plates by using abrasive water jet cutter. Uniaxial tensile and three-point bending tests have been carried out to obtain some mechanical characteristics such Young's modulus, tensile strength, break strain, flexural strength and modulus of the hybrid composites. DMA measurements also performed to compare nanoclay effect. The results of this study demonstrated that the mechanical behavior was positively affected by nanoclay addition into epoxy resin. The tensile strength and flexural strength significantly increased compared to the non-nanoclay hybrid composite (pure). However glass transition temperature (T g) of hybrid composites decreased with increasing amount of nanoclay.

Effect of Cu Nanoparticles on the Properties of PP-g-PHMG/PE Monofilament and Its Antifouling Application

“…This indicates that the stiffness is remarkably enhanced by the increased CuNP content of the monofilament [16]. Ünal et al also reported a similar phenomenon in nanoclay containing fiber-reinforced hybrid composites [33].…”

Cotton waste and nanoclay‐based phenolic novolac epoxy composites and evaluation of their properties

“…This may be due to less crosslinking density between the clay layers or the varying stoichiometry between the epoxy and the curing agent 61,62 . In contrast, some studies have reported a decrease or almost a slight increase in T g 63,64 …”

“…61,62 In contrast, some studies have reported a decrease or almost a slight increase in T g . 63,64 In general, the water uptake of a composite system depends on several factors, for example, the hydrophilic or hydrophobic nature of the matrix and the filler, the interfacial adhesion between the filler and the matrix, and the voids in the composite structure. 65 It is important to determine the water absorption properties of materials because it is known that water absorption of polymers causes plasticization, deteriorates their mechanical properties (modulus of elasticity, tensile, and other strengths), and causes hydrothermal degradation (e.g., microcracks).…”

Surface Modification of Cellulose Nanocrystals with Lactone Monomers via Plasma-Induced Polymerization and Their Application in ABS Nanocomposites

“…In Figure 10 c, the storage module of the ABS nanocomposites is shown, in which it can be observed that the ABS/0.25CNC C150 nanocomposite presented the highest elastic modulus in relation to pure ABS. Young’s modulus values evaluated through stress tests were much lower than the storage modulus determined by DMA, possibly because the material was not completely isotropic and in addition to the fact that stress was not applied to the direction of the specimen [ 39 ].…”
