“…The reason for this is that L (300) has very little effect on the impact response compared to L≫10b (10*180=1800) which is the case for beam with a length-to-width ratio of (300/180=1.67). In case of beam, length-width ratio is large with L≫10b, so the length-oriented layup has a significant impact on the impact response, but the width direction is minimal [2]. Figure 6 from Table 2 shows that there are some errors in maximum contact durations (2 times of time at maximum contact force of present results and contact duration of (WPM) but the over all trend is well matched, and the maximum contact force is pretty much the same.…”

“…Wuite et al [1] used the classical laminate theory to analyze nanocomposite beam and to not link them to the Hertz's contact law. Recently, Meybodi et al [2] investigated low-velocity impact response of a nanocomposite beam by using Euler-Bernoulli beam theory and Hertz's contact law. However, there has been a strong need to introduce a high-order theories to increase the accuracy of the analysis results.…”

A refined impact finite element approach in conjunction with the Reddy's higher-order shear deformation theory and Hertz's contact law is applied to study the influence of stacking sequence and nanoclay content on impact response of nanoclay/epoxy nanocomposite of 20 layers and 5 mm thickness. Combinations of four typical stacking sequences and six nanoclay contents inside epoxy, namely, the stacking sequences [0 20 ], [90 20 ], [0/45/0/-45/0] 2S , [90/45/90/-45/90] 2S , and nanoclay contents 0, 1, 3, 5, 7, 9wt.% at [0/45/0/-45/0] 2S are considered. The results of this analysis for four stacking sequences show that the unidirectional layup ([0/45/0/-45/0] 2S and [90/45/90/-45/90] 2S) and cross-ply layup ([0 20 ] and [90 20 ]) in this nanocomposite plate indicate, the same impact response, respectively. In addition, from results of nanoclay contents 0, 1, 3, 5, 7 and 9 wt. % at [0/45/0/-45/0] 2S , it can be seen that the greater the rigidity of between 0 to 7wt. %, the greater the contact force and the smaller the deflection, the smaller the COR becomes. However, at 9wt. %, the rigidity is reduced, causing the opposite effect of all impact responses.

In recent times, basalt fiber reinforced polymer (BFRP) nanocomposites is being increasingly used in aerospace applications such as wing and fuselage structures of the aircraft and outer casings of the rocket, automobile engine drive shafts and fuel tanks in the oil and gas industries, which fills the gap between carbon and E-glass fiber reinforced polymer nanocomposites. These structures are subjected to vibrations and exposed to different temperatures in various places during their service life. However, the comparison of vibration response of silica particles reinforced basalt/epoxy and glass/ epoxy nanocomposite tubes in all three approaches, namely, experimental, analytical and numerical (Finite Element Modeling), have not found elsewhere. Analytical and numerical approaches minimize time, manpower and cost. Therefore, investigating the vibration response of different weight contents of these FRP nanocomposite tubes is novel and essential. Hence, in this study, the vibration response of silica nanoparticles reinforced epoxy, basalt/epoxy and E-glass/epoxy composites with different weight contents (0, 0.5, 1 and 1.5%) were investigated. The vibration tests were performed at three different boundary conditions such as cantilever, simply supported and fixed-fixed. The first three modes of vibration were considered for analysis. Besides, the heat deflection temperature and the hardness properties were also studied. The results indicate that the natural frequencies were higher for the fixed-fixed case and the damping parameters were higher for the simply supported case. Vibration properties, heat deflection temperature and hardness values were found to be higher in fiberreinforced nanocomposites than those of epoxy nanocomposites. The data presented in this study will be useful to generate the numerical models for the ground vibration test (GVT).

“…In general, different nanoparticles or nanotubes of clays [10,16,22] alumina [11,14], silica [7,8,12,17], carbon [6,13,15,16,18] and graphene [6,20] have been added in polymer systems because of the improved mechanical properties. It was seen that all these particles improved mechanical and damage tolerance properties.…”

Composite structures utilized in defence and aerospace applications might be subjected to impacts due to bird strike, tool dropping and bullet penetration. One of the approaches to this problem is to add nano tubes and nano particles to resin systems in order to improve bonding between fibres and matrix materials. Different nano-particles or nano-tubes of clays, alumina, silica, carbon and graphene have been analysed in composite systems in the literature so far because of the improved mechanical properties. In this study, the low velocity impact behaviour of the aramid fibre reinforced epoxy composite plates, containing two new nano-particles of TiC and ZrC which are not studied formerly, are searched experimentally. After the low velocity impact tests, it is concluded that plates containing titanium carbide nano-particles and zirconium nano-particles yielded 19 % and 4 % respectively less penetration in comparison with particle free plates. In other words, titanium carbide nano-particles contained plates showed more resistance against the impact by 19 % against to particle free plates. These results showed that TiC and ZrC nano particles might be also good contributors for the impact resistance of composite structure.
