Table 3: Maximum load obtained for different harsh solutions and immersion time (values in kN). any increase in temperature accelerates short-term diffusion and increases the diffusion coefficient. Simultaneously, due to different coefficients of thermal expansion existing between fibres and matrices, residual stresses occur that are favourable to the occurrence of micro-voids or cracks in the fibre-matrix interface [48]. Under such conditions the aggressive solution creates a hydrostatic pressure at the crack tips and accelerates the crack propagation and matrix damage [49]. For example, [PERSON] et al. [50] developed studies on quasi-isotropic e-glass/epoxy composites immersed into artificial seawater and observed a decrease of 27% in tensile stress due to plasticization, but the failure was mainly governed by fibre failure and debonding of the fibre-matrix interface. [PERSON] et al. [51] reported that the lower tensile strength observed was a consequence of hydrolysis, cracks due to swelling, debonding of the fibre-matrix interface and plasticization. According to [PERSON] et al. [52], water absorption affects the tensile strength of carbon/epoxy composites due to plasticization of the matrix and degradation of the fibre-matrix interface, but the tensile modulus is not as affected as the tensile strength. Simultaneously, authors also reported that the observed degradation is more influenced by water than by temperature, although the latter accelerates the diffusion. In terms of interlaminar shear strength (ILSS), [PERSON] et al. [52] observed a decrease between 20% and 30%, which is explained by the authors due to matrix plasticization and degradation of the fibre-matrix interface, values that have been confirmed by other studies [53; 54]. As consequence of these phenomena, impact strength is also affected [55]. In addition, Table 4 also shows that the impact load values are lower for laminates that have been immersed into distilled water than in seawater. This evidence is in line with the studies developed by [PERSON] et al. [54], in which the diffusion coefficient in purtuded carbon/epoxy composites immersed into water was higher than in those immersed into seawater. According to the authors, the dissolved particles into seawater obstruct the osmotic water diffusion. For example, [PERSON] et al.
