Abstract

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