“…Electrical measurements were performed on the same samples as were used in thermal conductivity tests. Electrical resistance was measured using a Cen-Tech p37772 digital multimeter across the sample in the fiber direction (1), perpendicular to the fiber direction (2), and in the out-of-plane direction across the composite thickness (3). Resistance was converted to conductivity in milli-Siemens per centimeter (mS/cm) following the equation,…”

Graphene has generated substantial interest as a filler due to its exceptional strength, flexibility, and conductivity but faces obstacles in supply and implementation. A renewable, plant‐based graphene nanoparticle (pGNP) presents a more accessible filler with the same properties as mineral graphenes. In this study, we examine the effects of pGNP, which was sprayed on a carbon fiber/epoxy prepreg at loadings from 1.1 to 4.2 g/m2. The study considered the mechanical, thermal, and electrical properties of pGNP‐composite. An even particle dispersion was achieved using a spray application of pGNP in a water/alcohol suspension with the addition of surfactants and dispersion aides. Results show that pGNP addition increases flexural modulus 15%, flexural strength 17%, interlaminar shear strength 17%, and mode I fracture toughness by 146%, as well as increases electrical conductivity 294% and thermal conductivity 24%, with these improvements observed at 1.1–2.3 g/m2 spray loadings.

“…To further improve the fracture toughness of laminates, carbon nanofillers such as carbon nanotube (CNT), [21][22][23][24] carbon black (CB), 25 and graphene (GN) 26,27 were introduced into the interleaves. Liu et al 28 reported a 206% increase in G IC of laminates after inserting PES film interleaves containing 10 wt% multi-walled CNTs. Therefore, PES film interleaves loaded with carbon nanofillers have great potential to improve the fracture toughness of laminates.…”

Functional polyethersulfone (PES)/carbon black (CB) films were fabricated and interleaved into carbon fiber/epoxy composite laminates to simultaneously improve the mode I interlaminar fracture toughness (G IC ) and delamination monitoring sensitivity. It was found that when the CB content in the functional film was 7.5 wt%, the initial and propagation G IC of the laminate achieved the greatest improvements of 99.16% and 82.83%, respectively. The toughening mechanism was mainly attributed to the formation of phase separation structure, the plastic deformation of PES and the pull-out of epoxy and CBs. Meanwhile, a delamination increment-resistance change relationship equation was proposed to predict the delamination increment of the laminate during mode I delamination. Moreover, the effect of CB content in the film on the delamination monitoring sensitivity was investigated. The pure PES film showed the largest sensitivity coefficient k of 4.55, which was much higher than that of Control (0.14). When the CB content was in the range of 2.5-7.5 wt%, both G IC and k remained at relatively high levels, indicating that PES/CB films have promising applications in advanced multifunctional composites due to their low cost, simple manufacturing process, and largescale industrial manufacturability.

Polymeric composites are becoming increasingly popular materials due to their wide range of uses in heat shielding materials for solid rocket motors and aerospace applications. Novel polymeric composites are prepared and evaluated containing chopped carbon fibers, glass fibers (GF), and basalt fibers (BF), besides, recently used fillers such as Kevlar fibers (KF), and fumed silica (FS) to study their effects on the mechanical, thermal, and ablative properties of the ethylene propylene diene monomer (EPDM) hybrid composite. Mechanical, chemical, thermal, and ablative tests are performed to show the performance of the prepared polymeric composites. Experimental investigations have shown that the addition of GF to the EPDM matrix has a great influence on raising the tensile strength to 6.570 MPa. By incorporating KFs into EPDM, a solid char layer is formed during ablation, resulting in the best ablative performance with a decrease in the ablation rate of 73%, while the addition of FS, and BF to EPDM gives the best thermal stability results with total weight loss of 80.34%, and 81.77%, respectively.
