“…For anisothermal conditions, it was noticed that the temperature of the decomposition onset (Td,onset) shifts to higher temperature with increasing the heating rate, whether the testing atmosphere is oxidizing or not. Regarding C/PPS composites, it was reported that the presence of carbon fibres delays the onset of pyrolysis under oxidizing atmosphere, in agreement with conclusions presented in the literature on PPS and PPS-based composites [12]. The activation energy calculated from MT-TGA suggests the existence of three different mechanisms during pyrolysis under inert atmosphere: depolymerization, random chain scission and ultimately cyclisation (char formation) [7,10].…”

Considering their increasing use in high-temperature aeronautical applications, thermoplasticbased laminates have to meet certification requirements in terms of critical service conditions (e.g. aircraft engine's fire). This work is aimed at identifying the most relevant approach to model the isothermal decomposition of C/PPS composites. The first step in the understanding of the thermal decomposition of these materials relies on TGA and MT-TGA tests. They can be conducted in isothermal and anisothermal conditions to characterize the thermal decomposition kinetics taking place in a fire scenario. The experimental database obtained from these tests is of major importance to identify input parameters of pyrolysis kinetics models. The predictive capabilities of three different approaches (model-fitting, isoconversional/modelfitting and model-free) is discussed based on statistical analyses (Fisher's test). For C/PPS laminated composites, these approaches are virtually statistically equivalent. Model-fitting methods result in relatively accurate predictions of the TGA curves at a given heating rate.However, this type of approaches is not fully satisfactory especially when it is used to predict the thermal decomposition of polymer-matrix composites under anisothermal conditions.Finally, the model-free approach is identified as the most relevant from a physical point of view to account for the thermal decomposition of C/PPS composites under isothermal conditions.

“…1 Among advanced thermoplastic polymers, polyphenylene sulfide (PPS) has been used widely in structural parts due to its easy processability, excellent tensile strength, flexural modulus, low water absorption, and appropriate thermal resistance. [1][2][3][4] However, in these structural applications, PPS is most commonly reinforced with carbon fibers (CF) fabrics. PPS/CF composites have also demonstrated good retention of mechanical properties and fiber-matrix adhesion under hot-wet conditions.…”

In order to investigate the combined action of temperature, humidity, and ultraviolet (UV) radiation, polyphenylene sulfide (PPS)-carbon fiber composite specimens were exposed to environmental degradation through two different techniques: water immersion and UV climatic chamber. The moisture weight gain curves of the composites were compared with those of the neat matrix in order to determine the interface effect on moisture absorption. Fourier-transform infrared spectroscopy of UV-weathered samples presented oxidation formation. Compressive tests and dynamic mechanical thermal analysis (DMA) revealed that the weathered materials gained in stiffness, nevertheless a small deterioration in strength was found after long periods of UV radiation exposure.

“…The cross-linking mechanisms under air highlighted by Ma et al could partly explain this phenomenon. 33 At lower temperatures, as the decomposition of the decomposition is slow, partial cross-linking of the matrix in parallel could result in less extensive could result in less extensive pyrolysis and therefore earlier oxidation.…”

This study investigates the influence of a combined thermal heat flux (imposed by a cone calorimeter) and a compressive loading on the deformation and damage mechanisms within quasi-isotropic carbon fibers reinforced PolyEtherEther Ketone laminates. Thermogravimetric Analyses conducted at increasing heating rates under nitrogen (from 5 to 500°C/min) provide valuable information on the thermal decomposition of C/PEEK that ranges from 550°C to 627°C, with a corresponding mass loss ranging from 20 to 26%. From the thermo-mechanical coupling standpoint, the softening and the thermal decomposition of the PEEK matrix under a 50 kW/m2 heat flux result in the micro-buckling of fibers bundles in matrix-rich areas at the ply scale. Ultimately, it leads to the formation and propagation in the transverse direction of plastic kink bands at the laminates scale. Post-failure observations show that this macroscopic kinking propagates specifically according to the PEEK matrix pyrolysis.
