Abstract :
Research on the potential application of bamboo in airline industry is still in the enfant stage compared to related civil engineering in building construction. This study focuses on Bambusa vulgaris a dominant bamboo species in Cameroon, to evaluate its potential for airline industries. B. ulgaris with age ranging from 1-3 years, 4 -5 years and 7 years were characterized, by submitting specimens to several tests: 1) the chemical treatment with 5% of NaOH, 2) density measurement using both Rilem proctocol and a helium pycnometer, 3) tensile tests, 4) scanning electron microscopy (SEM) analysis, 5) Fourier-transform infrared spectroscopy (FTIR), 6) thermal conductivity, 7) thermogravimetric analysis and 8) the specific heat capacity measurement conducted with a differential scanning calorimetry (DSC) 9) the dynamic mechanical analysis (DMA). The young’s modulus of B. vulgaris with ages ranging from 1-3 years, 4 -5 years and 7 years were around 10 GPa, 15 GPa, and 23 GPa respectively. The results of the dynamic mechanical analysis (DMA) with temperature range from -80°C to 250 °C performed on 7 years old B. vulgaris showed that the storage modulus at -80,34°C and 50,64°C was around 26 GPa and 22 GPa respectively. The specific heat capacity at 23°C was around 1.2 KJ. K-1.Kg -1. A comparative study on the properties of others natural fibres tested in aeronautic and aerospace industries revealed that B. vulgaris with 7 years old has good properties for airline industries. This study provided evidence that 7 years old B. vulgaris has the potential important role to play in aeronautical and aerospace composites materials.
