“…Ayatollahi et al (2011) have performed experiments on nanocomposites and have reported that by adding more MWNTs the viscosity of the mixture increases which makes the degassing of mixture more difficult. The synthesis route adopted in the present study was via a conventional hand layup technique as outlined elaborately by Chandra Shekar et al (2013). The densification and curing process is carried in a muffle furnace in three heat treatment cycles.…”

Studies have been carried out to evaluate interlaminar shear behaviour of carbon nanotube and carbon fiber reinforced, epoxy matrix hybrid composite. Short beam shear (SBS) tests were conducted to characterize the influence of fiber orientation in the interlaminar shear strength (ILSS). Experimental details, specimen configuration, data acquisition and processing are presented in detail. The present study reveals the importance of alignment of fiber and its effects on ILSS properties and nature of deformation under shear loading conditions. The results show that the interlaminar shear strength of the hybrid composite is significantly higher in longitudinal orientation as compared to the same in transverse orientation; and more importantly show that such anisotropy is of an order of magnitude and higher.

“…High strength values with high strength to weight ratio are obtained when compared to other competing polymer matrix composites. 12 Tensile strength and Flexural strength were increased in glass and flax fibre reinforced composites having MWCNT content of 1 wt.% upto28.26%. Compressive strength was decreased initially and then rapidly increased while increasing the MWCNT of 1 wt.%.…”

In this present study, the mechanical properties of Glass/Carbon hybrid composite reinforced with epoxy resin with and without multi-walled carbon nanotubes (MWCNT) were investigated. The composite under Experimental analysis were fabricated by using both Hand layup and Vacuum bag moulding processes. The main purpose of including MWCNT as a reinforcement material with epoxy is to reduce the existence of voids or cavities and to enhance the mechanical properties of Glass/Carbon hybrid composites. Because of their extraordinary mechanical properties and high aspect ratio, MWCNTs are considered to be ideal candidates for polymer reinforcement. The percentages of MWCNT selected for the study are 2%, 3% and 4% with the hybrid composites. The effect of MWCNT on mechanical properties such as tensile strength, compressive strength, flexural strength, impact strength, hardness and percentage of water absorption of the hybrid composites were determined as per American Society for Testing and Materials (ASTM) standards. The result from the study shows that the mechanical properties of hybrid composites were improved with the addition of small amount of MWCNT than without MWCNT. The fractured specimen from Tensile test is examined by using Energy Dispersive X-Ray Analysis (EDX)to study the alignment of the fibres, fibre-matrix adhesion, voids and filler agglomeration. This investigation provides proper guidelines to designers on enhancing mechanical properties of Glass/Carbon composite structures through MWCNT reinforcement for Aircraft structural components.

“…These materials are used in aerospace, transportation, wind turbine blades, electromagnetic interference shielding, and expensive sporting goods, etc. [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ]. It is very important to understand whether CNT is attracted more by carbon fiber or epoxy resin in order to control the CNT dispersion.…”

In this study, the three-phase structure consisting of epoxy resin, carbon nanotubes (CNTs), and graphene, which is assumed to be the surface of carbon fiber, was simulated using molecular dynamics. Models in which the CNT number and initial position of CNT are varied were prepared in this study. Relaxation calculation for each three-phase model was implemented, and the movement of molecules was investigated. When CNTs are located between the graphene and epoxy at initial, how the epoxy approaches to graphene was discussed. Besides, interaction energies between CNT/graphene, CNT/epoxy, and graphene/epoxy were evaluated after relaxations. The value of the interaction energy between two individual molecules (epoxy resin and graphene, CNTs and graphene, epoxy resin and CNTs) among three-phase structure were obtained, respectively, and those mechanisms were discussed in this study.
