Abstract EN
In the present search, attempts are made to develop the properties of PMMA resin that used for upper and lower prosthesis complete denture, by addition two different types of particles, which included: nano-hydroxyapatite (nHA) particles and micro-zirconia (ZrOR2R) particles that added with different volume fractions of (1%, 2 % and 3 %) to poly methyl methacrylate (PMMA) cold cured resin as new fluid resin matrix.
Also woven glass fiber kind (E-glass) and woven Kevlar fiber kind (49), it were added with a fixed volume fraction of (5%) to PMMA composites.
In this work the composite prosthetic dentures specimens preparation was done by using (Hand Lay-Up) method as six groups which includes: the first group consists of PMMA resin reinforced by nHA particles, the second group consists of PMMA resin reinforced by ZrOR2R particles, the third group consists of (PMMA-nHA) and glass fiber layer as laminated composite , the fourth group consists of (PMMA-ZrOR2R) and glass fiber layer, the fifth group consists of (PMMA-nHA) and Kevlar fiber layer and the sixth group consists of (PMMA-ZrOR2R) and Kevlar fiber layer.
The experimental part of this study included performing many mechanical tests which, includes (Flexural, Maximum Shear Stress and Impact) tests.
The result of this study showed the values of most properties increased with increasing of the volume fraction of (nHA and ZrOR2R) particles in polymer composite materials.
While, the impact strength decreased.
The ZrOR2R particle and woven mat Kevlar fiber had shown greater values for the most composite materials properties for all groups’ specimens except the flexural strain.
Also the results showed the maximum values for hybrid laminated composite properties (flexural modulus and impact strength) were obtained in hybrid laminated composite materials for sixth group specimens.
While, the maximum value for properties (flexural strength and max shear stress) were obtained in hybrid laminated composite materials for fourth group specimens
