“…These experimental data were taken at the volume ratios of the hybrid system using micro‐sized and nano‐sized particles at 50 : 50. Because experimental work reported that a ratio of 50 : 50 gives a positive effect in particles dispersion and electrical conductivity, the validation was implemented in this state, while the total Ag micro‐sized and nano‐sized filler loading was fixed at 6 vol.%. The electrical conductivity value of experimental results reached 4.03 × 10 −1 S/cm.…”

This paper presents a new approach in modeling the particle dispersion structure of micro-nano silver particles of conductive adhesive considering the van der Waals interaction energy. As there are many possible combinations of hybrid micro-nano system, this work only focuses on two types of micro-nanoparticles interconnecting; the first is single microparticles with nanoparticles, and the second is two microparticles with nanoparticles. The particle coordinates were imported into CAD software to produce 3D geometry, and finally, the finite element method was used to determine the electrical conductivity. The experimental data were taken at the volume ratios of the hybrid system using micro-sized and nano-sized particles at 50 : 50 for validation purpose. As a result, the predicted electrical conductivity shows a good agreement with experiment data with error less than 4%. Simulation result gives a value 1.46 × 10 1 , 9.18, 6.86 and 4.54 S/cm for single-micro/50 nanoparticles, single-micro/75 nanoparticles, single-micro/100 nanoparticles and single-micro/125 nanoparticles, respectively. The electrical conductivity is optimum in a particular nano-size number as it could settle interconnection path in shorter particle chain. The electrical conductivity show decreasing by increasing particle network chain due to nano-particles added.

This paper presents the effects of the filler type and testing temperature on the charge dynamics and thermal properties of the epoxy resin. The micro‐nano hybrid composites with different content of the micro and nano aluminum nitride (AlN) fillers are fabricated. The morphology of micro‐nano hybrid composites is characterized. Electrical testing and thermal analysis methods are adopted to analyze its electrical and thermal performance. The results show that the space charge accumulation is suppressed and the charge decay process is facilitated in the hybrid composites. The electrical performances of the hybrid composites are enhanced by the nano‐fillers. The apparent mobility and activation energy are decreased with nano‐AlN fillers in the composites at the high temperature. The glass transition temperature and thermal stability of the materials is improved with the nano‐AlN. A hypothetical mechanism is proposed to explain the charge carrier injection and transport of the composites at different temperatures.

The effect of the geometry of metallic fibers on the mechanical response of aluminum fiber-reinforced composite adhesive joints was studied experimentally. Moreover, a combination of multi-walled carbon nanotubes and aluminum fibers was used for reinforcing the composite adhesive joints. Different geometries for the aluminum fibers including straight, twisted and spring-shaped with different pitch lengths were considered. The results indicated that the composite adhesive joints reinforced with a combination of multi-walled carbon nanotubes and aluminum fibers experienced the highest improvement of 171% in the strength compared to the unreinforced specimen. It was found out that the aluminum fiber geometry can significantly influence the adhesive joint behavior. Incorporating the twisted aluminum fibers into the adhesive layer increased, while the spring-shaped fibers decreased the strength of the composite adhesive joints compared to the straight aluminum fibers. The fracture surfaces of the composite adhesive joints were analyzed using scanning electron microscope.
