Flax fibers were chemically modified on their surface with aldehyde-based glutaraldehyde, glyoxal or butryaldehyde to enhance their adhesive interconnections with polypropylene (PP) matrix. Mechanical (tensile and elastic) properties were most improved with glutaradehyde modification compared with glyoxal or butryaldehyde. Using glutaraldehyde modified flax fibers, the optimal modification paramet...<br/><br/>Lu S.H., Xie L., Steuernagel L., Gerhard Z. (2012) <i>Soft Materials</i> : <br/>

Two kinds of wood particles with different sizes and properties were compounded with polypropylene (PP) in highly concentrated levels (by 50% and 60% weight concentration). Their flow abilities were estimated by viscosity–shear rheological test and spiral flow mold respectively; the results show that higher concentrations result in poor flow ability. However, to estimate the relation between par...<br/><br/>L Xie, Timo Grueneberg, Leif Steuernagel, Gerhard Ziegmann, and Holger Militz (2010) <i>Journal of Reinforced Plastics and Composites </i> 29: 13 1940-1951<br/>
