Fiber-reinforced epoxy composites exposed to high temperature environments. Part II: modeling mechanical property degradation

Abstract: This article is part of a series on the thermo-mechanical responses of fiber-reinforced composites at elevated temperatures and it follows the first part containing experimental results. A flame-retardant system consisting of a cellulosic charring agent and an interactive intumescent additive (melamine phosphate) has been used in order to improve the post-fire mechanical performance of glass fiber-reinforced epoxy composites. The effect of one-sided radiant heat on the residual flexural stiffness of laminate c… Show more

“…For validation of models discussed in subsequent sections, eight ply glass -fibre reinforced composite laminates were fabricated via a wet lay-up method using a low-viscosity and low temperature-curing base epoxy resin containing 1,4-butanediol diglycidylether, (Araldite LY5052) and a hardener based on modified cycloaliphatic amines (HY5052) (Huntsman, Inc.); woven roving E glass (300 g/m 2 ) (Glasplies, 5 UK). The composite fabrication details are given elsewhere [13]. Two types of composite laminates were prepared; a control (EP) and a fire-retarded sample (EP20) containing 20% w/w fire retardant additives in the resin.…”

“…This work presents further refinement of our recently developed heat transfer model, Kandare et. al., [13], based on Henderson's equation, which predicts the through-thickness temperatures of the laminates exposed to radiant heat, but only prior to ignition of the laminate. The refinement allows measurement of time and temperature of ignition, and through-thickness temperature profiles of the burning laminates.…”

“…Furthermore, Henderson and Wiecek [9,10] improved the 1D thermal model to predict the thermal behavior of the composite material, taking into account the thermochemical expansion [11] in the depth orientation of the sample, as well as the flow and accumulation of decomposition gases. Gibson and Mouritz et al [12][13][14][15][16], Kandare [17], Desjardin [18], Summers et al [19], and Bhat et al [20,21] further improved the pyrolysis kinetic model for thermal analysis of composite laminates in a fire environment. Anjang et al [22] developed a thermal model for sandwich composites by improving the Henderson and Gibson models.…”

“…The thermal and fire performances of fiber-reinforced composites depend upon the resin and fiber type, their mass/volume fraction composition and fiber configuration [1,2]. When exposed to high heat fluxes, the heat transfer and the resulting temperature rise through the thicknesses of samples depend on the density, thermal conductivity, and specific heat capacity values of both the resin and fiber components, as well as the kinetics of their decomposition [3][4][5], although the latter is applicable to resins only in the case of these composites. The thermal and mechanical performance of most thermosetting resins is dictated by their functionality.…”
