Fiber-reinforced polymer (FRP) composites have become more popular in civil engineering applications over the last three decades as a result of their superior properties when compared to traditional construction materials like concrete and steel. However, due to growing environmental concerns over excessive CO2 emissions stemming from the increased usage of petroleum-based materials, a new trend in the building business is to reduce carbon emissions.
Natural fibers are being examined as a possible replacement for synthetic fibers in the manufacture of bio-based composite materials.
Poor fire resistance and high flammability are the two main concerns with FRP composites, especially bio-based FRPs, and limit their use in structures. When compared to traditional construction materials, the properties of FRP fluctuate dramatically with temperature and must be properly tested using defined test procedures. While there is considerable guidance on the necessary test procedures for characterizing FRP composite properties at ambient temperature, there is less guidance on the test methods for describing capabilities at increased temperatures.
