【 摘 要 】

The aim of this study was to estimate the influence of the UV ageing process of the polymer matrix composites (PMC). Samples were prepared using 2 types of prepregs in the form of: (1) fabrics and (2) unidirectional fibers. The samples were aged in an accelerated weathering chamber for various times. Then the uniaxial tension tests were conducted using the DIC (digital image correlation) method to monitor deformation process of the PMC in time. Changes of the tensile strength and the Young modulus were experimentally estimated and compared to reference samples without ageing.
