In this article, we investigated the interfacial, thermal and ablative properties of two nanofillers‐filled carbon/phenolic (CF/PR) composites. In particular, graphene oxide (GO) and graphitic carbon nitride (g‐C3N4) were used to produce lowly loaded (0.1 wt%) composites. The ablative properties of the composites were researched through an oxygen–acetylene flame torch test and were characterized through analysis of the post‐burning morphology, ablation depth and width. GO‐ and g‐C3N4‐filled composites showed 62.02 and 22.36% improvement in ablation resistance compared with the pristine, respectively, even with different mechanisms. The proposed mechanism of GO‐filled composite is that GO may significantly contribute to increasing the graphitization of the fiber surface and further improving the thermal resistance to high‐temperature ablation. However, thicker fiber diameter and charred layer of ablative zone in g‐C3N4‐filled composite can dissipate the flammable gases and improve the anti‐oxidation. POLYM.

“…Giants [36] based on his research and experience suggests that we must carefully control the curing conditions of the propellant, liner, and insulation for optimum interfacial adhesion. It was also reported that incorporating the epoxy phenolic resin into an ethylene propylene diene monomer (EPDM) insulation is an effective way to enhance the bonding properties of EPDM insulation of carbon fibre/epoxy composites which is a new material used as the motor case [37].…”

One of the most challenging requirements in a solid rocket motor (SRM) is the integrity of the charge structure which is a multilayer adhesive joint involving the propellant, liner, and insulation. The propellant/liner/insulation interface is considered to be the weakest part of the whole structure. This interface has some of the usual features of an adhesively bonded interface, as well as its own special characteristics: the co-cured process, ingredient migration between interfaces, and complicated damage mechanisms. We give a technical and critical review of the past fifty years of existing research on many aspects of the propellant/liner/insulation interface in terms of the adhesive properties and adhesive mechanisms, ingredients migration, damage determination, and fracture analysis.To present a comprehensive outline of this interface we also clarify some remaining problems which should be addressed in the future. With significant improvements in the theoretical and experimental studies of the propellant/liner/insulation interface, the problem of integrity failure of the charge structure in SRM will be well resolved.

“…Thus, during intensive impingement of high temperature combustion gases, poor tenacity results into fracturing and sloughing of the formed char layer. 47 The carbonaceous char from the BR acts as reinforcement for the hexagonal arrangement of the amorphous turbostratic carbon. 48 Figure 3 shows the various stages of the flame test, viz.…”

Disposal management of waste, discarded and unserviceable Butyl Rubber (BR) is a matter of environmental concern which requires immediate attention. Wastage of expensive rubber which is used in all types of rubber gaskets, seals and hoses, should be recycled and reused for reclamation of the rubber raw materials. The present study proposes novel, ecological and prudent heat resistant hybrid composites of Resorcinol Formaldehyde (RF) and waste BR, fabricated through in-situ polymerization and tested under oxyacetylene flame at 2300 C for 60 s for ablative properties. The composite exhibits high ablation resistance, quantified by a drop of Mass Ablation Rate from 0.079 for pristine RF to 0.068 compared to pristine resin due to increase in the formation and retention of insulative turbostratic char. Thermogravimetric Analysis (TGA) reveals the degradation traits with a 13% enhanced char residue up to 800 C. These composites pose competition with respect to cost effective heat shields as Thermal Protection Systems (TPS) in re-entry vehicles and space shuttles and fire proofing materials.
