Influence of Relaxation State of Polymeric Components of Wood on Its Fatigue Strength | Chapter 6 | Novel Aspects on Chemistry and Biochemistry Vol. 8

 The hotness behavior of Siberian larch forest sap, which is a complex arabinogalactan (AG) - water, has happened studied. It is proved that this complex is eutectic and provides extreme fatigue strength of wood until low hotnesses (up to -60oC), impregnating the blood vessel-porous structure of wood. It is settled that the complex AG-water being a natural eutectic fit also shows the possessions of plasticizer.

Research on Strength, Fatigue Strength and Stiffness of High-Tech Bamboo/Epoxy Composites | Recent Advances in Science and Technology Research Vol. 2

A major problem in the strength data available for cellulose fibre‐based materials is that the moisture content of the test specimens is rarely measured, and yet it is the dominant variable in the tests. Detailed strength and stiffness results are presented for Brazilian Dendrocalamus Giganteus bamboo at a wide range of moisture contents down to 2% and the fatigue curve is given for Chinese Moso bamboo at 4% moisture content. Techniques are described for handling the variability of these natural materials, both in design and in manufacturing quality control, for the mass production of large, hightech composites wind turbine blades.
