Abstract Thermogravimetric analysis (TGA) and derivative thermogravimetry (DTG) are used to investigate the thermal degradation and thermal stability of the prepared bamboo/glass hybrid composites in a nitrogen atmosphere. The analysis is carried out in the temperature range of 0 C to 800 C at a heating rate of 20 C min-1 with the nitrogen gas flow of 55 ml min-1. The hybrid glass/bamboo with coconut shell powder in micron and nano-size confirms a mass loss of 32.50% and 33.50%. Tensile and fatigue results confirm that the bamboo/glass hybrid composite added with coconut shell powder in micro- and nano-size exhibits good fatigue property and restrict crack initiation and crack propagation under cyclic loading. Fatigue analysis reveals that at 800 cycles, the hybrid bamboo/glass fibre-reinforced plastics (FRP) composite with nanoparticles posses 22.5% higher load compared to all other combinations. Finally, the fatigue life increases with decreasing the filler dimension of the hybrid composites. TGA/DTG analysis reveals that hybrid

1 Introduction Thermogravimetric Analysis is an important technique, which is used to determine the mass of the sample as a function of temperature change and time. [1]. Recently, TGA is mainly used to characterize the materials like thermoplastic and thermosetting polymer matrix, and also determines the influence of hybrid fibre-reinforced polymer matrix [2]. The polymer materials like thermoplastic and thermosetting polymer matrix are essential to examine the characteristic and the influence of addition of natural fibres into the polymers, which can be determined by effective method known as thermal evaluation [3]. The thermal stability and decomposition rate of material can be obtained from TGA [4]. The TGA also can analyse the materials which exhibit mass gain or mass loss due to oxidation resistance or decomposition. This is particularly useful for the study of polymeric materials like thermosets, thermoplastics, films and elastomers [5]. Usually, the thermal property of natural fibres which is used as a reinforcem
