In this study, HAp
reinforcement into UHMWPE matrix having 1.0 % wt. mass and its effects on microstructural
and mechanical properties of the UHMWPE composites were investigated. UHMWPE
composites reinforced with 0.5, 1 and 2.0 wt. % nano HAp powders, respectively
were successfully produced by solution and gelation method. SEM studies showed
that HAp nano particles were homogenously distributed into UHMWPE matrix and good
cross-linked with the matrix. SEM-map EDS analysis confirmed SEM. FTIR results
revealed that HAp incorporation into matrix was conducted and crystallization
of UHMWPE increased by increment in amount of HAp results in deepening
crystallization peaks at nearby 500 and 1500 cm-1. DSC results, which is useful technique to
determine the variation of melting point and crystallization ratio of UHMWPE
composites, indicated that there was no remarkable change in melting points of
composites, while crystallinity of the samples generally showed slight increase
by increasing amount of nano HAp particles. The tensile test instrument was
utilized to determine elastic modulus of the samples and their elastic modulus
were raised from 1050 to 1900 MPa with higher HAp reinforcement. It can be
concluded that UHMWPE-2 % wt. HAp composites have promising results by being
paired with crystallinity and elastic modulus.
