A Model for the Thermal Response of Polymer Composite Materials with Experimental Verification

Abstract

The thermal response of a polymer composite material undergoing decomposition has been modeled. A one-dimensional transient thermal model with an nth order ap proximation for the rate of decomposition was applied. The model was tested by ex perimentally measuring the temperature profiles during decomposition for a glass- filled phenol-formaldehyde polymer composite. Additionally, the specific heat and thermal conductivity of the virgin and char components, heat of decomposition, and the kinetic parameters were experimentally determined and used as input to the model. The predicted temperature profiles are in good agreement with experimental temperatures obtained using a radiant heat flux apparatus.

Numerical Simulation of Two-dimensional Ablation Heat Transfer Process Based on Moving Mesh

“…In numerical test, thermal physical properties of materials is obtained from the reference [10].as shown in Table 1. The thickness of the original material layer and the ablative material layer are all 1cm and the width is 4cm.…”

Hybrid Carbon-Carbon Ablative Composites for Thermal Protection in Aerospace

“…Thermal modelling developed by Henderson et al is the common model for calculating the temperature distribution in composites. This one-dimensional nonlinear equation accounts for the energy transfer through heat conduction, pyrolysis mechanism, and diffusion of decomposition gases which is shown in the following [82]:…”

Modelling Reaction-to-fire of Polymer-based Composite Laminate

“…Since then, these models have been adapted for modelling the heat and mass transfer through fibre-polymer composite material in fire. Several researchers , Henderson & Doherty (1987a), Henderson & Wiebelt (1987b), Florio et al (1989), Sullivan & Salamon (1992a), Sullivan & Salamon (1992b), Perring et al (1980), Mc Manus & Springer (1992a), Mc Manus & Springer (1992b, Dimitrienko (1995), Davies et al (1995a) Dimitrienko (1997), Milke & Vizzini (1991), Gibson et al (1995), Davies & Wang (n.d.), Looyed et al (1997), Gibson et al (2004), Lattimer & Ouelette (2006), Trelles & Lattimer (2007)] have developed different approaches but the most influential work in this area came from Henderson et al (1985). Research on the effects of fire on sandwich composite has used the same principle as single monolithic composite in terms of modelling [Davies et al (1995a), Davies et al (1995b), Looyed et al (2001), Krysl et al (2004), Galbano et al (n.d.), Marquis (2010a)].…”

“…A complete review is given by Ott (1981), Henderson et al (1985), Gibson et al (2004) and Mouritz & Gibson (2006). The temperature dependence of thermal conductivity can also be expressed as a linear combination of the virgin material and char conductivities, weighed by the ratio of the solid material mass to the initial virgin mass or final char density ].…”
