Abstract: Fiber reinforced polymeric composites are new classes of advanced materials and have been used in numerous industries, such as transportation, energy, defense, and infrastructure because of their excellent strength, stiffness, corrosion, impact, fatigue and creep properties. However, the polymeric composites suffer from fire and lightning strike damages. Metallic skins can help reduce these damages but are heavier and can corrode in the long service unless the specific metals and alloys are selected. Thermal and electrical conductivity of composite surfaces can be significantly increased by applying metallic films, such as Ti, Cu, Ni, Ag, Cr and their alloys. Among them, micron size Ti and Cu films / plates with higher corrosion resistance can be manufactured and used for fire retardancy purposes for the composites without adding much weight on the vehicles. The objective of this study is to develop fire retardant fiber reinforced composites using modified resin and metallic Ti and Cu films, and test and characterize the properties of the prepared composite structures. Wet-layup process was utilized to produce composite panels under vacuum, and then determine the flame retardant and other physical and chemical properties before and after resin modification and surface film coatings. This study also included the demonstration of small-scale prototype development and implementation processes. The mechanical, chemical, and thermal studies indicated that these highly robust modified resins and conductive metallic films provided superior flame retardancy and mechanical strength on the composite panels. This study may open new avenues to enhance the physical and chemical properties of fiber reinforced composites for different manufacturing industries at various conditions.
