“…Note also that, in the synthesis of the chemical elements of the sampling zones along the RV stem, the percentage of carbon is in between 51% and 57% while that of oxygen varies in the interval of 41%-48%. Such an observation was also made for Roselle, palm, and hemp fibers [20,39].…”

In this paper, the physicochemical and mechanical properties of Raffia vinifera pith (RVP) are discussed. Microscopic observations have shown that the structure of the RVP is similar to that of a composite consisting of natural fibers. The effective area ratio of Raffia vinifera (RV) fibers was evaluated along the raffia stem using ImageJ software, and it decreases from the periphery to the center. Energy dispersion spectrometer (EDS) analysis shows that RVP is essentially composed of carbon and oxygen. Densities of RVP and its matrix were determined using Archimedes’ principle and law of mixtures, respectively; from the results obtained, they can be considered as one of the lightest materials. Young’s modulus of RVP has been obtained from tensile and bending tests, while that of matrix has been obtained using the law of mixtures during tensile tests. RVP has better specific properties, and the results of the matrix properties show that we can easily select another matrix which has better properties than the case studied during the elaboration of composites.

In this study on characterization of bambusa vulgaris fibers from Cameroon (BV), we evaluated the linear density as well as the moisture uptake. With the help of SEM, the cross-sections were observed to be circular shapes; they increase from outside to inside in any transverse position along the stem. Also, the degradation temperature of BV was investigated with the aid of TGA and the result showed that the degradation temperature of BV fibers is between 366 °C and 380 °C. In addition, their Young's moduli in dynamic tensile test was determined and it was noticed that the Young moduli increase from inside to outside. The bending tests of BV fibers were carried out and enable the various parameters in zone 3/3. Finally, the creep behavior of BV fibers was studied and it was revealed that the 4-element Burger model describes very well this phenomenon and could help in well predicting fatigue behaviour of BV fibers reinforced composites.
