“…In terms of the improvement in K IC and G IC compared to that of the pure EP, the results is not particularly significant compared to the reported results. Taoet al [7] reported that the K IC of the composites is lower than that of pure EP when adding the same amount of Fe 2 O 3 particles in the EP, which is similar to that of the composites without MF. However the percentage of increase in K IC and G IC of the composites with MF is lower than that in the work [5].…”

Abstract. The magnetic iron oxide (Fe 2 O 3 ) nanorods were synthesized, and the epoxy resin (EP) composites with the content of 1wt% Fe 2 O 3 were prepared in the condition of magnetic field. X ray diffraction, scanning electron microscopy and comprehensive physical properties measurement system were used to characterize the composition, morphology and magnetic properties of the nanorods, respectively. The effects of a low magnetic field (≤0.06T) on fracture toughness, compressive strength and glass transition temperature of the composites were specifically investigated. The results show that the critical stress intensity factor, critical strain energy release rate and the compressive strength of Fe 2 O 3 /EP composites with magnetic field induction are 1.33 MPa·m 1/2 , 0.56 KJ/m 2 and 206.5MPa, which are increased by 7.3%, 27% and 15% compared to of EP effectively.

The active screen plasma technology was used to functionalize carbon fibers and vitreous carbon disks. The plasma treatment conditions were mapped using optical emission spectroscopy and the functionalized surfaces were analyzed using scanning electron microscopy and atomic force microscopy, x-ray photoelectron spectroscopy, and contact angle measurements. A relationship was found between the active species in the plasma and the functional groups attached to the carbon surfaces, which provides valuable information for the optimization of the active screen plasma treatment. Moreover, the surface analyses were repeated over a period of 28 days to study the aging of the functionalized surfaces in air. The hydrophobic recovery was modeled using a surface restructuring theory which revealed a mean lifetime of 3.4 days for the functional groups. V

A glass-fiber, grafted by hyperbranched polymer with hydroxyl group (GF-HBPH), reinforced epoxy-based composite was evaluated for mechanical properties and compared with the neat epoxy and silanized glass-fiber, GF-APS. The epoxy/GF-HBPH composites were studied by attenuated total internal reflectance infrared spectroscopy, 1 H nuclear magnetic resonance spectroscopy, thermal gravimetric analysis, mechanical properties analysis, and field emission-scanning electron microscopy. The results showed that the incorporation of GF-HBPH could simultaneously enhance the mechanical properties of the epoxy composites. Field emission-scanning electron microscopy images of the fracture surfaces of the test specimens were used to support the results and conclusions.
