Degradation Mechanism of Glass/Polyester Composite Exposure to Acidic and Alkaline Solutions at Room Temperature

Abstract:

The aim of this work is the studyof the degradation mechanism of a glass fiber/unsaturated polyester (UP) composite immersed inacidic(H₂SO₄)and alkaline(NaOH)solutionslike establishing a relation between the chemical and the mechanical behaviors of this material. The gravimetric analyses showed a pseudo fickianbehavior for the samples immersed in H₂SO₄ and mass losses with a pseudo-stage of saturation as from 64 hours of immersion for the samples immersed in NaOH.The Fourier transform infrared analysis (FT-IR)of the UP resin revealed the presence of chemical degradation phenomenon (hydrolysis).Microscopic observations (SEM) confirmed the fibres/matrix interfacesdegradation. The effect of these degradations has been reflected one the mechanical properties of the materials.
