The polyimide-modified epoxy resin was designed through cross-linking reactions between epoxy resin and polyimide, forming the film material. The heat resistance and flame retardation of the NPMFs were attributed to the introduction of inorganic fillers. The results demonstrated that NPMF-3 significantly delayed the ignition of CCCs, withstanding temperatures of 270 °C for 109 s, thus, enhancing heat resistance by 104.1%. Meanwhile, the saltwater absorption rate of NPMF-4 was only 6.92 wt%, which was reduced by 82.10 wt% compared to the uncoated CCC sample. The maximum storage modulus value of all NPMFs exceeded 2000 MPa. Compared to the uncoated CCC sample, the tensile strength and elongation at break of NPMF-3 increased by 203.52% and 570.24%, respectively. Additionally, the corrosion rate of the Zn-Fe alloy samples coated with NPMFs was significantly lower than the uncoated samples, indicating strong protection against salt corrosion.

While residual stress analysis has been extensively studied in the context of metal-plastic hybrids, the residual stress condition is unknown for thermoset-thermoplastic hybrids produced by injection molding. Therefore, we firstly apply a calculational model to estimate the residual stress for the investigated material combination of glass fiber-filled polyamide (PA6.6 GF30) and a unidirectional glass fiber-reinforced plastic (UD-GFRP) with a polyurethane acrylate matrix. Secondly, these results are compared to a corresponding computational simulation model. Integrating Fiber-Bragg-Grating (FBG) sensors in the UD-GFRP allows for the determination of residual strain in the thermoset component at different temperatures and thereby both the calculational and computational simulation methods could be validated against experimental results. The results show that process-related residual stresses occur in the hybrid composite and are not negligible. Normal stresses of − 39.6 MPa have been observed in thermoset material.

To solve this problem, we propose a combined melt-wet processing, which allows predictable and tunable morphologies. The process consists in combining Material Extrusion (MEX) with an eco-friendly salt leaching in distilled water, by using a biostable polymer and high percentages of saline porogen. Three blends with PA6/NaCl-30/70wt% composition were extruded, varying the salt particles size, that shows good dispersion in all the filaments, with a spontaneous tendency for bigger particles to accumulate in the central region of the cross-sections, attributable to fluid-dynamic reasons. Blends rheological and mechanical properties appeared suitable for the printing process. The hollow devices were then printed and successfully leached, resulting in homogeneously dispersed pores, with size ranges comparable to those of the porogen for each blend; therefore, the morphology of the pores can be directly predicted by the porogen and it was not altered during processing. Leaching occurred completely, in fact the real porosity for each device was consistent with the theoretical one. Despite the high percentage of voids, the hollow devices appeared to be mechanically resistant and therefore suitable for the application. Controlled release up to 11 days of a model molecule (methylene blue) was tested and predictable kinetics related to pore size were achieved so, therefore, they are easily tunable and versatile.
