Abstract

Feather/plastic composite material was fabricated from polymethyl methacrylate (PMMA), feather fiber (FF) and  montmorillonite (MMT) using brabender internal mixer. PMMA based composites were produced with 1, 3, 5, 7 and 10 phr composite of mass feather fiber with and without 4 % of montmorillonite (MMT). Alkali treatment was used to improve the interfacial adhesion among the feather fiber (FF) and the PMMA. Flexural properties of FF/PMMA and FF/PMMA/MMT composites were investigated. Composites were analyzed by Scanning Electron (SEM) and Fourier Transform Infra Red (FTIR) spectroscopy techniques. The result showed that, the addition of FF significantly increased the flexural strength of the composites. The hydrophobic nature of feather fiber displayed an excellent compatibility among fibers and PMMA matrix.

 

Keywords: PMMA, Feather Fiber, alkali treatment

 

Abstrak

Dalam kajian ini, bulu / bahan komposit plastik telah diperbuat daripada polimetil metakrilat (PMMA), serat bulu (FF) montmorilonit (MMT) menggunakan brabender percampuran dalaman. PMMA komposit dihasilkan berasaskan dengan 1, 3, 5, 7 dan 10 phr komposit berat serat bulu dengan dan tanpa 4% daripada MMT. Kaedah rawatan alkali telah digunakan untuk meningkatkan lekatan antara muka antara serat bulu dan PMMA. Sifat mekanik FF/PMMA dan FF /PMMA/ MMT komposit kekuatan lenturan itu telah disiasat. Spesimen yang diperolehi dianalisis dengan mikroskop imbasan elektron (SEM) dan teknik spektroskopi FTIR. Keputusan menunjukkan bahawa penambahan FF meningkatkan kekuatan lenturan bahan komposit ini. Sifat hidrofobik serat menunjukkan satu keserasian yang baik antara gentian dan matrik PMMA.

 

Kata kunci: PMMA, serat bulu, rawatan alkali
