Book excerpt: The heat transfer in an anisotropic thermosetting advanced composite during its cure was investigated experimentally and then modeled analytically as well as empirically. AS4/3501-6 graphite/epoxy was used for the experiments. A cure kinetics model based on the variation of resin peak exothermic temperature was compared to the experimental data for the resin degree of cure measured at various times for a series of constant temperatures. This model predicted the experimental values well for temperatures above 150°C but did not perform as well below this temperature. The specific heat of the composite was found to decrease with temperature when the resin is a liquid but to increase with temperature when the resin gels and becomes a solid. Models have been developed to predict the thermal conductivity of the fiber-reinforced composite as a function of fiber volume fraction, resin degree of cure, ply layup angles measured in any direction and for various fiber/matrix contact conductances. These models were experimentally verified using a guarded hot plate apparatus to measure the thermal conductivity of the graphite/epoxy as a function of these variables through a range of typical cure temperatures. A second order tensor transformation of the principal thermal conductivities was experimentally verified for the fiber-reinforced composite. A unique experimental procedure was designed to measure the off-axis conductivities of an anisotropic composite material. A new self consistent model for the transverse thermal conductivity of a fiber-reinforced composite predicts the experimental data better than seven models previously derived by other authors which were also compared to the data. The self consistent model predicts a percolation threshold near a fiber volume fraction of 48%. A model for the effective transverse conductivity of a material with cylinders arranged in rectangular order, first derived by Lord Rayleigh, was modified to account for the possible effects of a fiber/resin contact resistance and for the transversely anisotropic behavior of the composites' thermal conductivity.

Book Synopsis Cure Simulation of Thick Thermosetting Composites by : Travis A. Bogetti

Available in PDF, EPUB and Kindle. Book excerpt: The potential for enhanced performance characteristics of composite materials over conventional metals, such as high strength-to-weight ratio, high stiffness, corrosion resistance and low radar signature, makes them extremely attractive for a wide range of military applications. The curing process of thick-section thermosetting composites is critical to the quality and in-service performance of the finished component. In this paper, an investigation into the two-dimensional cure simulation of thick thermosetting composites is presented. Temperature and degree of cure distributions within typical glass/polyester and graphite/epoxy structural elements of arbitrary cross-section (ply-drop and angle bend) are analyzed to provide insight into the non-uniform curing process unique to thick-sections. An incremental, transient finite difference solution scheme is implemented to solve the pertinent governing equations and boundary conditions. Correlation between experimentally measured and predicted through- the-thickness temperature profiles in glass/polyester laminates are presented for various arbitrary temperature cure cycle histories. Spatial gradients in degree of cure are shown to be strongly dependent on part geometry, thermal anisotropy, cure kinetics and the temperature cure cycle. These spatial gradients directly influence the quality and in-service performance of the finished component by inducing warpage and residual stress during the curing process. Keywords: Thermoset composites; Thick laminates; Cure simulation; Anisotropic heat conduction; Boundary fitted coordinates; Finite difference theory.
