Carbon fibre composites offer considerable potential for mass reduction in automotive applications. However, raw material cost is one of the major factors that constraints its extensive use this market. Here we report a systematic study presents contributors by considering entire process chain carbon manufacturing. The sensitivity analysis revealed final Polyacrylonitrile (PAN) precursor and fibres were strongly influenced tow size. It was observed prompt decrease per kg sizes from 3k to...
Here we report on how residence time influences the evolution of structure and properties through each stage carbon fibre manufacturing process. The chemical structural transformations density variations in stabilized fibres were monitored by Fourier Transform Infrared Spectroscopy column studies. microstructural property variation subsequent studied X-ray diffraction monofilament tensile testing methods, which indicated that thermally at longer times showed higher degrees conversion...
This study presents the conversion of polyacrylonitrile (PAN) co-polymers containing methyl acrylate (MA) and varying concentrations itaconic acid (IA) comonomers, from precursor fibre into carbon using pilot scale continuous processes. The impact on processability, thermal behaviour, energy consumption, final mechanical properties during oxidative stabilization (TOS) carbonization are investigated. Itaconic concentration varies 0.3 to 3 wt% with increasing acid, exhibited lower...
Carbon fibre composites are lightweight, high performance materials with outstanding mechanical properties.
Abstract This study investigates the influence of printing parameters on tensile properties and void architecture poly(lactic) acid (PLA) parts fabricated using fused filament fabrication (FFF) technique. Two Taguchi optimisation methods were employed to identify optimal parameter combinations for maximising performance. The results revealed a positive correlation between performance nozzle diameter (ND). Notably, analysis coefficient variance (COV) studies that both strength modulus...
This study quantitatively defines the temperature induced chemical transformations and evolution of radial heterogeneity during stabilisation carbon fibre precursors.
We report the production of automotive grade carbon fibers in a low temperature carbonization furnace by making use influence various levels tensions and temperatures on polyacrylonitrile (PAN) precursor fibers. The experiments were performed at two different during process to understand effect differences as well tension. oxidative stabilization processes structure, mass retention, mechanical properties was analyzed. Fibers collected from each zone high furnaces, physical measured for along...
A liquid bio-derived eugenol-containing phosphorus silicone hybrid molecule (EGDS-DOPO) that endows excellent flame-retardancy and enhanced mechanical performance to an epoxy amine network at low levels of addition was successfully synthesized characterised. The EGDS-DOPO significantly improved the flame retardancy requiring only 5 wt% achieve a limiting oxygen index (LOI) 34.9 % UL 94 V-0 rating. Cone calorimetry measurements reveal reduction peak heat release rate, total release, smoke...
Despite the many positive aspects of carbon fiber arising from its light-weighting potential, high cost and related environmental impact may inhibit even wider usage material in future. The need to incinerate gaseous emissions generated during manufacture significantly contributes both eco-impact cost, while information regarding these on a production line scale is lacking due confidentiality behind commercial manufacturing. A detailed assessment evolved gases underlying mechanisms using...
Process parameters, especially in the thermal stabilization of polyacrylonitrile (PAN) fibers, play a critical role controlling cost and properties resultant carbon fibers. This study aimed to efficiently handle energy expense areas during fiber manufacturing without reducing quality We introduced new parameter (recirculation fan frequency) stage studied its influence on evolution structure Initially, progress cyclization reaction cross-sections with respect frequencies (35, 45, 60 Hz) was...

Abstract Nanoindentation is an effective and powerful tool for the measurement of mechanical properties at small scales. Standard nanoindentation test rates are higher than most tests that include tension, compression, flexural tests. However, to achieve studies require several thousands indents, need be further improved without compromising data quality. Here we report possibility increasing testing by first altering duration pre-test routines then quantifying rate effect on hardness (H)...
