A new composite manufacturing technique called continuous curing is discussed and analyzed. This method is especially suited to the manufacture of thick composite materials in which thermal spiking is a common problem. Thermal and cure fronts are propagated in the thickness direction as material is accreted on the outer surface. An experimental apparatus was designed and built for use with a filament winder to continuously cure thick composite cylinders. A demonstration experiment was carried out using IM6/3501-6 graphite/epoxy prepreg tow. A hoop-wound composite cylinder with 152 mm wall thickness was manufactured and embedded thermocouples and strain gages were monitored throughout the cure process. Results indicate that very thick and good quality composite cylinders can be fabricated without long manufacturing time, material degradation due to thermal spiking, and high level of thermally induced residual stresses.

Frontal polymerization is a mode of polymerization in which a localized zone of reaction propagates through the coupling of thermal diffusion and the Arrhenius dependence of the reaction rate. The dependence of the front propagation velocity on the initial composition has been determined in initially miscible binary systems of a free-radically cured diacrylate and an amine-or cationically cured epoxy resin. A minimum of the velocity as a function of the monomer mole fraction is observed if the two polymerizations occur independently. Excellent agreement with an analytical description was found with the diacrylate and an amine-cured epoxy but not for a diacrylate and a cationically cured one because of the effect of HCl impurities on the peroxide.

“…To overcome the disadvantages of the traditional manufacturing method of filament winding, studies on on-line thermal processing of thermoset composites in filament winding have been conducted in recent years. Korotkov et al [2] presented a onedimensional (radial direction) heat transfer model for the simultaneous processes of filament winding and curing of thermoset composites in which the surface of the composite was heated by infrared irradiation and a heated mandrel. Chern et al [3] studied in situ curing for thermoset, hoop-wound structures using infrared heating.…”

A helical tow model of on-line curing of thermoset composites in winding is developed and solved numerically. Actual shape of tow in winding process is considered, and consequently, the modeling of the on-line curing process is more realistic. A numerical grid generation method is developed for the complicated geometry. Transformations of three-dimensional energy equation and its boundary conditions from physical domain to computational domain are performed, which are crucial in numerical grid generation method when an anisotropic medium is involved. A set of concise and regular equations is obtained. The numerical simulation results show that the helical tow model, in stead of a simplified model, should be used when the ratio of the diameter of fiber-wound composite structure to the diameter of tow is small.
