“…The toughness mechanisms such as crack pinning, crack deflection, HNT debonding are observed at regions close to the fiber–matrix interface during SEM examinations in multi‐scale GFRP composite after low‐velocity impact tests. Ravichandran et al [ 45 ] were observed crack bridging, pull‐out, or breakage of HNT nanotubes as toughening mechanisms on HNT‐modified epoxy nanocomposites. When a crack comes across with a nano‐scaled HNT particle, it tries to pull out the particle if it has enough energy.…”

One of the biggest obstacles to fiber-reinforced composite laminates is out-ofplane dynamic loading. Specifically, low-velocity impact loading in an out-ofplane direction leads to matrix cracking, delamination, and fiber breakage damages due to weak fiber-matrix interactions. This paper aims to examine the dynamic loading behavior of nano reinforced glass/epoxy composite laminates under various impact energies. Moreover, to enhance fiber-matrix interaction, halloysite nanotubes (HNTs) with lower cost among the nanotube morphologies such as carbon and TiO 2 were introduced to the epoxy matrix.The impact performance and the damage propagation were also investigated. As a result, the HNT-reinforced multiscale composite sample had 28% more impact load carrying capacity and absorbed 18% less energy than its unmodified counterpart. Image processing was utilized to determine the damage evaluation by analyzing both front and back surfaces. The improvement of the fiber-matrix interface with HNTs reinforcement resulted 59% and 46% less damage to the front and back damage surfaces, respectively. The acquired results were supported by macro-size examination and micro-size analyzing via scanning electron microscopy (SEM). These results pave the way towards designing fiber reinforced composites to be utilized for the transportation of dangerous liquids such as acids or solvents.

“…Alongside FMSPS, small portable solar panels (PSP) have gained popularity in the market, offering a relatively lightweight, cost-effective and portable solution for urgent energy needs [5]. However, it is important to note that the power generated by PSP packages is not competitive with FMSPSs, and their efficiency is nearly half that of conventional solar photovoltaic (CSPV) panels used in FMSPSs [6].…”

The Paris Agreement and the 2030 Agenda for Sustainable Development emphasize the urgent need to fight against all forms of poverty, advance sustainable development, and achieve a low carbon future. Electricity is critical for poverty alleviation, economic growth and living standards improvement. According to the World Bank, there is some improvement in global population access to electricity, although global energy access is still a real challenge with around 675 million people without access to electricity. Moreover, the number of people without electricity in sub-Saharan Africa (SSA) has rather increased with electricity reaching only about 50% of the population. In this context, a 4 kW foldable mobile solar power system (FMSPS) with 20 kWh energy storage has been developed and used as an educational tool for school outreach as well as a demonstrator for sustainable back-up power alternative to diesel generators for clean energy access in communities with high energy poverty. The system is uniquely designed to offer easy manufacturing, cost-effectiveness, high aerodynamic stability, and reliability alongside manual operation for minimal maintenance requirement. FMSPS was designed and manufactured as part of over £1 million funding awarded by Innovate UK under the Energy Catalyst Round 8 (Clean Energy Access) Competition. The collaborative research and development project aims to develop and demonstrate the next generation sodium-ion battery energy storage integrated with solar energy generation, to provide affordable and secure access to energy in SSA.

“…Jelić et al [ 25 ] modified HNTs with 3‐glycidyloxypropyltrimethoxysilane (GLYMO), APTES, and DGEBA, and then added them to the epoxy resin matrix, which improved the tensile strength of nanocomposites and the crosslinking degree of epoxy resin matrix. Hashmi [ 26 ] uses ultrasonic to realize the uniform dispersion of halloysite nanotubes (HNTs) in epoxy resin. Then the nanocomposites were prepared, and then the density, hardness, tensile, bending, ILSS and impact strength of the nanocomposites were evaluated.…”

KH550 modified halloysite nanotubes (m-HNTs) were hybridized with sulfoxide chloride acylated graphene oxide (m-GO) to prepare hybrid nanoparticles (HNTs-d-GO). The microstructure and morphology analysis of HNTs-d-GO hybrid nanoparticles showed that the ordered lamellar structure of GO after acyl chlorination was stripped, and the organic groups on the surface of the lamellar increased. HNTs-d-GO hybrid nanoparticles were formed through the amidation of m-HNTs and m-GO. Then HNTs-d-GO hybrid nanoparticles were incorporated in galic acid epoxy resin to improve the thermal and mechanical properties. HNTs-d-GO/galic acid epoxy resin (HNTs-d-GO/GAER) bio-based nanocomposites were prepared with methyl tetrahydrophthalic anhydride as curing agent. The galic acid epoxy composites with the addition of HNTs-d-GO exhibited significant enhancements of impact strength, tensile strength, storage modulus, and glass transition temperature. The initial thermal decomposition temperature (T 5% ) decreased, and the mass retention at 800 C increased, thermal stability of HNTs-d-GO/GAER composites were enhanced. At an optimum concentration of 0.75 wt% HNTs-d-GO, a simultaneous increase in strength and toughness was observed in comparison to the unfilled cured resin, the impact strength is 2.87 kJ/m 2 , which is 30.4% higher than pure GAER, and the tensile strength is 42.62 MPa, which is 29.2% higher than pure GAER. Compared with pure gallic acid epoxy resin, the content of HNTs-d-GO is 0.25 wt%, T g increased by 28.9 C.
