Abstract
Synthetic polymers such as polyurethane are used widely in the field of
biomedical applications such as implants or part of implant systems.
This work focuses on the preparation of base polymer matrix composite
materials by (Hand Lay-Up) method ,and studying the effect of selected weight
fractions (3 , 6 , 9 , 12 ,15) % wt of Calcium oxide (CaO) , Calcium carbonate
(CaCO3), Magnesium oxide (MgO) ,and Magnesium carbonate (MgCO3) particles
on some properties of the prepared composite.
Some mechanical tests were used to evaluate the prepared system (Tensile,
Compression, Impact, and Hardness) tests, and a physical test of (Water
absorption %), and all tests were accomplished at room temperature.
maximum results of tensile strength, compression strength, impact energy,
hardness, water absorption were ( (31 MPa),( 51 MPa),( o.265 J), (79.8 Shor (D)),
(0.229 %)) at using ( (9% wt (MgCO3)) , ( 9% wt of (MgCO3)) , ( 9% wt of
(CaCO3)) , ( 15% wt of (MgO)) , ( 15% wt of (MgCO3)) respectively
