Abstract

This article evaluates the mechanical properties of vacuum-infused unidirectional plant fiber composites (PFRPs), composing of bast fiber yarns and thermoset matrices. PFRPs are found to have lower fiber volume fractions than E-glass composites (GFRPs). Apart from the expected (30-40%) lower density of PFRPs, they have 60-80% lower tensile strength, 30-60% lower tensile stiffness, 5-10 times lower impact strength, and 20-30% lower interlaminar shear strength than GFRPs. Importantly, critical fiber lengths are of the same order (0.2-0.5 mm). Composites reinforced with flax rovings exhibit exceptional fiber tensile modulus of 65-75 GPa and fiber tensile strength of about 800 MPa. © 2014 Copyright Taylor and Francis Group, LLC.
