Titre: Élaboration et étude des propriétés des composites Polyester- Alfa traitée et non traitée Auteur(s): Mouhoubi, S.; Osmani, H.; Bali, T.; Abdeslam, S. Résumé: In the present work we have study the chemical treatment effect on the composites proprieties. Our composites have prepared in the No metallic materials laboratory (LMNM- Sétif). Those are building with the contact molded method under a sandwich form. We have introduced untreated and treated Alfa fiber mat in the resin polyester matrix. The chemical treatment that we have used is alkali treatment with 5% of NaOH during 6 hours. This results show that the chemical treatment have an important effect on the composites mechanical and physical behavior and also on the interface between vegetable fiber and polymeric matrix.
