Fiber-reinforced polymer (FRP) composites have been widely applied for about 60 years in many different fields, such as automotive industry, chemical industry, and civil construction. Because bioepoxy is renewable and environmentally friendly and has comparable mechanical properties (such as tensile, flexural, and bending properties) to petroleum-based polymer FRP, bioepoxy has been recently used as the alternative of petroleum-based polymer in FRP composites. This chapter provides a review on the previous investigations on natural/synthetic/hybrid fiber-reinforced bioepoxy composites. The chemical structure, mechanical properties (e.g. tensile and flexural properties), and application of the fibers and bioepoxy are introduced. Besides, the mechanical properties (tensile, flexural, and impact properties) of fiber-reinforced bioepoxy are also presented.
