PENGARUH PENAMBAHAN HIDROKSIAPATIT DAN KITOSAN PADA PLA DAN ABS TERHADAP SIFAT MEKANIK DARI KOMPOSIT BIOMATERIAL

The purpose of this study is determine the mechanical properties PLA-Hap-Chitosan and ABS-HAp-Chitosan composites. Poly lactic acid (PLA) acrylonitrile butdie styrene (ABS) are polymers that can be applied in biomedical field because they to decompose naturally human body. To streng not make body wear out, a ceramic element has bioactive, biodegradable biocompatible added, namely hydrochiapatite (HAp). In addition hydroxyapatite, chitosan also added as natural an anti-bacterial. materials used PLA ABS with variations using HAp powder chitosan. process making composite uses injection molding temperature 190oC on 250oC ABS. results showed caused decrease composite, was due difference polarity which led formation agglomeration resulted poor interactions, causing decrease. maximum aimed at composition 90-0-10 minimum 90-2-8. Meanwhile, for were 90-8-2 ABS-Hap-Chitosan composition.
