A methodology to reduce thermal gradients due to the exothermic reactions in composites processing

Experimental and modelling study of the radiative curing of a polyester-based coating

“…Nonetheless, few papers characterise the cure process of powder coatings by correlating thermal modelling of the cure process and kinetics studies [14,15]. This is the aim of the present study, in order to build the basis for a better control of the curing process.…”

“…The coating finish is more uniform and more resistant to mechanical impact. Cure kinetics studies of thermosetting powder coatings have been widely described in the literature [9][10][11][12][13][14][15]. Nonetheless, few papers correlate thermal modelling of the cure process and kinetics studies.…”

Curing of composites by radiation and natural convection in an autoclave

“…A cure cycle is selected to obtain high-performance materials. The optimization of thermal conditions and autoclave designed for production of composite materials is an active field of development and research in numerous industries (Antonucci et al, 2002;LeGrand and Bellenger, 1998;Li et al, 2001;Olivier and Cottu, 1998). Most studies primarily aim at reducing capital and energy requirements and improving the quality of products.…”

A Method for Cure Process Design of Thick Composite Components Manufactured by Closed Die Technology

“…resin [2]. Another important aspect is the complete and uniform resin polymerization (or minimum required extent of cure, α min ) after processing in order to improve the mechanical properties of the composite part, but it is not always accessible [3].…”

“…Aluminium or steel tools have a much higher expansion coefficients than composite parts, and tend to stretch the parts as they heat up. This can happen as a result of small shear stresses at the tool interface causing tension in the part [2,3,[9][10][11][12][13][14][15][16][17]. The AGP (After Gel Point) plays a significant role on the magnitude of process-induced residual stresses, as demonstrate in the works [15][16][17].…”
