Hybrid Vegetable/Glass Fiber Epoxy Composites: A Systematic Review

Hybrid composites have been drawing the attention of researchers in the composites field because of their high flexibility to tailor properties through fibers hybridization. The behavior of hybrid composites is dependent on nature, amount, processing parameters, among other parameters, of each reinforcing fiber and polymeric resin. Hybrid glass fiber/vegetable reinforced polymer composites combine the high performance of synthetic fibers with the ecological appeal of vegetable ones. When properly hybridized, the resulting properties can be satisfactory. This paper presents a systematic review of hybrid composites using glass fiber and vegetal fiber focusing on reports published in the last five years. The investigation follows PRISMA protocol, which delivers an accurate summary of all available primary research in response to a research question. After inclusion/exclusion steps, 52 papers were included in the review. The presented results focus on thermal, mechanical, and dynamic mechanical properties of hybrid composites. In brief, this methodology helps identifying the main gaps in the literature on hybrid vegetable/glass fiber epoxy composite laminates.
