The strongest before-aging adhesion in sanding and cross-grain helical planing is attributed to the microfibrils and fibers torn-out from the surface (de Moura and Hernandez 2005, 2006a, 2006b).
The microfibril angle of the G-layer is nearly parallel to the direction of the fiber axis.
One may note that PPV and recycled PP samples have similar elastic and yield domains but a reduction of the drawing behavior that may be because of the higher crystal content is observed for the recycled samples, as well as a decrease in the stretching of fibrils and microfibrils. All samples show stress-whitening as a consequence of craze nucleation.
The term microfibril angle (MF-angle) is used to describe the helical angles that microfibrils make in respect to the longitudinal axis of the cells.
In this work, more detailed studies have been done on the processability, physical, and mechanical properties of a new microcomposite developed by reinforcing NR with oil palm empty fruit bunch (OEFB) cellulose microfibrils. The effects of microfibril loading, orientation, and chemical treatments were studied.
The low longitudinal swelling is attributed to the predominately longitudinal orientation of the stiff cellulose microfibrils. At the cellular scale, swelling depends on whether latewood or earlywood is observed.
In addition, the mechanism of PBT microfibril formation was investigated by sampling at three different sites along the extruder.
Hence, these chains build up microfibrils with a high tensile strength.
These bundles may be distinct from single microfibrils. The red hash marks in Figure 3(a) correspond to the red circles on the line profile and are typically the darkest pixels in the image.
Fibrillin-1 microfibrils, through interactions with elastin and other proteins, provide structure to elastic and nonelastic connective tissues [7, 8].
Gene Ce1 shared a high homology (95%) with Pantholops hodgsonii collagen, type VI, alpha 3 (COL6A3), whose primary role is in assembling collagen VI microfibrils (Te-Cheng et al., 2013).
The fiber failure mode even shows the cellulose microfibrils still surrounded by the matrix and also considerable amount of fibers tearing was also noticed [19].
