摘要

In this study, acrylated epoxidized flaxseed oil (AEFO) resin is synthesized from flaxseed oil, and flax fiber reinforced AFT biocomposites is produced via a vacuum-assisted resin transfer molding technique. Different amounts of flax fiber and styrene are added to the resin to improve its mechanical and physical properties. Both flax fiber and styrene improve the mechanical properties of these biocomposites, but the flexural strength decreases with an increase in styrene content. The mass increase during water absorption testing is less than 1.5% (w/w) for all of the AEFO-based biocomposites. The density of the AEFO resin is 1.166 g/cm(3), which increases to 1.191 g/cm(3) when reinforced with 10% (w/w) flax fiber. The flax fiber reinforced AEFO-based biocomposites have a maximum tensile strength of 31.4 +/- 1.2 MPa and Young's modulus of 520 +/- 31 MPa. These biocomposites also have a maximum flexural strength of 64.5 +/- 2.3 MPa and a flexural modulus of 2.98 +/- 0.12 GPa. (C) 2014 Wiley Periodicals, Inc.
