The combustion characteristic of material in high oxygen concentration is directly related to the safety of elevated oxygen environment similar to oxygen bombs and future spacecraft. In this study, flame front and flame spread rate in high oxygen concentration are discussed. Thermoplastic material polyamide (PA6) and thermosetting material epoxy are selected as comparison material. The variation of flame front over epoxy is more stable than PA6 which has dripping phenomenon during the flame spread process. The flame spread rate of both PA6 and epoxy have a power law with the increasing oxygen concentration.
