Abstract
Composite materials may be subjected to an extreme condition where the surface is exposed to high-energy
photon radiation (e.g., laser radiation), which can cause severe damage and destruction of the structure
component. How the radiation energy is deposited in the composite material can greatly influence the
subsequent damage process, which may include local heating, phase transformation, heat-induced shock
waves, plasticity, etc. While the interaction of high-energy photons with homogeneous materials have been
well studied, it is still a challenge to model the photon transport in composite materials, which have been
increasingly used in more and more structural components. In this study, we propose a Monte Carlo model
to simulate the photons transport in structurally and chemically heterogeneous materials. The model is first
verified and validated by comparison with the existing open-source software Geent4 for a case study of
photon deposition curve in a single layer aluminum. The model is then applied to studying the photon energy
deposition in carbon fiber and epoxy resin. The simulation results show that while it is the epoxy resin that
is mainly exposed as the surface of the structure, the radiation energy is actually deposited more in the
carbon fibers than in the former. Detailed analysis shows that it is mainly due to the fact that the photon
absorption capacity of the carbon fiber is higher than that of the epoxy resin. We believe that this model has
the potential to be further applied to more complicated cases where the structural and material
heterogeneity may play a significant role in photon energy deposition.
