Fig. 4From: Comparison of traditional field retting and Phlebia radiata Cel 26 retting of hemp fibres for fibre-reinforced compositesStiffness (a), UTS (b) and porosity (c) of composites reinforced with untreated and treated fibres versus fibre volume (Vf) contents (k is slope of the linear regression model lines). Pectinase treatment was performed with and without prior autoclave treatment (HTT) at 1 bar (121 °C) for 30 min (Liu et al. 2016b)Back to article page
