Abstract

Abstract: Fiber reinforced epoxy resin composites were prepared by compression molding based on poplar wood fiber modified by methyl eleostearate maleic anhydride adduct (MEMA-PWF) and bisphenol A epoxy resin/methyl tetrahydrophthalic anhydride (E51/MeTHPA). Surface properties and fracture morphology of the epoxy composites were characterized by a contact angle measurement and scanning electron microscopy (SEM). The impact strength and flexural strength were tested. It was shown from the results that the surface hydrophobicity of modified fiber, the compatibility between the modified fiber with epoxy matrix, and the mechanical properties of MEMA-PWF/epoxy composites were significantly improved. The impact strength and flexural strength of the composites were 7.95 kJ/m² and 55.42 MPa, respectively. The composites had a better hydrophobic perfor- mance.
