Study of the mechanical behaviour of a short glass fiber-reinforced polyamide 6,6. In this experimental work, we studied the mechanical behaviour of a short glass fibre reinforced polyamide frequently used in the automotive industry. In order to investigate the influence of glass fibre content, relative humidity and strain rate, we carried out uniaxial tensile tests on an unfilled polyamide and glass fibre reinforced polyamide with different weight fractions: 10, 20 and 30 wt%. Experimental results showed that the studied composite is a strain rate, moisture and fibre volume fraction dependant mechanical behaviour. The thermography infrared (IR) technique has been used to determine the change of the surface temperature at the surface of materials during tensile tests. The local deformation process can be identified and studied from the infrared thermal images.
