Once blistering occurs you may must exchange the fabric covering the affected area, the same as your would for splitting, as mentioned above. Thus, the endothermic results on the Raffia palm fibers are seen in three progressions: dehydrogenation, evaporation of some cellulosic supplies and the thermal decomposition of the material. A small peak present at 78˚ of XRD of Raffia palm fiber depicts the presence of the Silica. Moreover, the peak at 13,656 cm? The peak at 1442.Seventy five cm? A peak found at 1280.Seventy three cm? The vaporization of water passed off at the first endothermic peak, the burning of cellulose and volatile matter happened between the first endothermic peak and the last endothermic peak, while at the last peak, the utmost thermal decomposition occurred. Energy dispersive spectrometer (EDS) used for the microanalysis to quantify the elements within the Raffia palm fibers present that the RPFAp has larger carbon(C) peak than the RPF. However, the graphitic peaks will not be very prominent in RPF samples. The results are expressed when it comes to a transient response factor (TRF), which is equal to the ratio of the fluctuating part of stress throughout the membrane thickness to the fluctuating component of wind pressure.
