Paragraph starter
Research by Bhongade and Borkar (2016) demonstrated that lignin can act as an effective compatibilizer in sunn hemp fiber-reinforced epoxy composites, leading to improvements in impact, tensile, and flexural strength. However, they also noted that excessive lignin content could negatively affect these properties by hindering resin infusion, highlighting the importance of optimizing additive concentrations.
