In the present study, a magnetic textile was developed by the application of Iron nanoparticles on cotton fabrics. For this, Fe3O4 nanoparticles were synthetized by reverse co-precipitation. Then, the obtained magnetic nanoparticles were applied on cotton fabrics using the Pad-Dry-Cure process. Magnetic behavior of iron oxide nanoparticles was investigated to study magnetic properties by the VSM analysis. Moreover, the effect of iron oxide nanoparticles on the cotton fabrics noticed on the thermal behavior has been studied by thermogravimetric analysis. The thermal stability of cotton fabrics is positively affected after the treatment using Fe3O4 nanoparticles. Finally, electrical properties were studied to measure the fabrics conductivity according to the AATCC.

Thermoset polymers offer great opportunities for mass production of fiber-reinforced composites and are being adopted across a large range of applications within the automotive, aerospace, construction and renewable energy sectors. They are usually chosen for marine engineering applications for their excellent mechanical behavior, including low density and low-cost compared to conventional materials. In the marine environment, these materials are confronted by severe conditions, thus there is the necessity to understand their mechanical behavior under critical loads. The high strain rate performance of bonded joints composite under hygrothermal aging has been studied in this paper. Initially, the bonded composite specimens were hygrothermal aged with the conditions of 50 °C and 80% in temperature and relative humidity, respectively. After that, gravimetric testing is used to describe the moisture diffusion properties for the adhesively bonded composite samples and exhibit lower weight gain for this material. Then, the in-plane dynamic compression experiments were carried out at different impact pressures ranging from 445 to 1240 s−1 using the SHPB (Split Hopkinson Pressure Bar) technique. The experimental results demonstrated that the dynamic behavior varies with the variation of strain rate. Buckling and delamination of fiber are the dominant damage criteria observed in the sample during in-plane compression tests.
