دراسة الخواص الميكانيكية لمادة البولي أستر المقوى بسعف النخيل المعالج كيميائياً بمحاليل خل التفاح و هيدروكسيد NaOH الصوديوم و حامض الهيدروكلوريك HCl

الملخص EN

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).
