“…The storage modulus, loss modulus, and Tan of TCE hybrid composites are plotted against temperature and demonstrated in Figure 2. These data provides insight into the stiffness of the composites, representing the elastic nature of the material [40]. Figure 2 shows the plots of storage modulus and loss modulus, against temperature in the range from −60 to 140 ∘ C for the various wt.% (15, 32 and 40) of TCE composites.…”

Various amounts of short fibers (glass and carbon) and particulate fillers like polytetrafluoroethylene (PTFE), silicon carbide (SiC), and alumina (Al 2 O 3 ) were systematically introduced into the thermoplastic copolyester elastomer (TCE) matrix for reinforcement purpose. The mechanical properties such as storage modulus, loss modulus, and Tan by dynamic mechanical analysis (DMA) and three-body abrasive wear performance on a dry sand rubber wheel abrasion tester have been investigated. For abrasive wear study, the experiments were planned according to 27 orthogonal array by considering three factors and three levels. The complex moduli for TCE hybrid composites were pushed to a higher level relative to the TCE filled PTFE composite. At lower temperatures (in the glassy region), the storage modulus increases with increase in wt.% of reinforcement (fiber + fillers) and the value is maximum for the composite with 40 wt.% reinforcement. The loss modulus and damping peaks were also found to be higher by the incorporation of SiC and Al 2 O 3 microfillers. The routine abrasive wear test results indicated that TCE filled PTFE composite exhibited better abrasion resistance. Improvements in the abrasion resistance, however, have not been achieved by short-fiber and particlaute filler reinforcements. From the Taguchi's experimental findings, optimal combination of control factors were obtained for minimum wear volume and also predictive correlations were proposed. Further, the worn surface morphology of the samples was discussed.

AbstrakPenelitian ini bertujuan untuk mendapatkan karakteristik mekanik komposit serat alam khususnya serat rami dengan matriks epoksi yang akan diaplikasikan sebagai bahan alternatif pada desain soket prostesis. Fokus penelitian adalah pengujian komposit lamina serat rami epoksi mengacu standar American Society for Testing Material (ASTM) D 3039/D 3039M untuk pengujian tarik dan ASTM D 4255/D 4255M-83 untuk pengujian geser. Serat rami yang digunakan adalah serat kontinyu dengan kode produksi 100% Ne 14'S, menggunakan matriks berupa Epoxy Resin Bakelite EPR 174 dan Epoxy Hardener V-140. Metode pembuatan sampel uji komposit lamina dengan cara hand lay up terhadap serat rami kontinyu pada suhu kamar. Hasil pengujian karakteristik mekanik komposit serat rami epoksi akan dibandingkan dengan standard ISO untuk bahan plastik/polymer yang diaplikasikan pada bidang kesehatan, khususnya untuk Prosthetics dan Orthotics. Analisis dilengkapi dengan hasil pengamatan berbantuan Scanning Electron Microscope (SEM) untuk mengetahui modus kegagalan dan kriteria kegagalan. Berdasarkan hasil pengujian dapat disimpulkan bahwa komposit lamina serat rami epoksi berpotensi untuk dikembangkan lebih lanjut sebagai material alternatif dalam pembuatan soket prostesis atas lutut pada Vf 40-50%. Hasil penelitian akan dibahas secara lebih detail dalam makalah ini. AbstractMechanical properties of ramie fiber reinforced epoxy lamina composite for socket prosthesis. This paper presents an investigation into the application of natural fiber composite especially ramie fiber reinforced epoxy lamina composite for socket prosthesis. The research focuses on the tensile and shear strength from ramie fiber reinforced epoxy lamina composite which will be applied as alternative material for socket prosthesis. The research based on American Society for Testing Material (ASTM) standard D 3039/D 3039M for tensile strength and ASTM D 4255/D 4255M-83 for shear strength. The ramie fiber applied is a fiber continue 100 % Ne14'S with Epoxy Resin Bakelite EPR 174 as matrix and Epoxy Hardener V-140 as hardener. The sample composite test made by hand lay up method. Multiaxial characteristic from ramie fiber reinforced epoxy composite will be compared with ISO standard for plastic/polymer for health application and refers strength of material application at Prosthetics and Orthotics. The analysis was completed with the mode of the failure and the failure criterion observation by using Scanning Electron Microscope (SEM). Based on results of the research could be concluded that ramie fiber reinforced epoxy composite could be developed further as the alternative material for socket prosthesis on Vf 40-50%. Results of the research will be discussed in more detail in this paper.
