Study of Mechanical Properties for Polyester Reinforced by Date Palm with Maleic, NaOH, and HCl Chemical Treatments


In this paper achemical treatment with (Maleic, NaOH, HCl) solutions ataconstant concentration with different times (3, 18, 72, 168, 240 Hours) isconducted in natural fibers (Date palm) are used as reinforcing phase in polyestermatrix to form composites. Mechanical properties of these composites such asflexural strength, impact are evaluated and possible chemical reaction taking placeduring composite making. Maleic treatment showed a relatively good effect inimproving the mechanical properties of the composite. Flexural strength andimpact energy reached the maximum values of (2.912 MPa) and (3.4 J)respectively at immersed time (18 Hours).
