Abstract

Hands play an important role in daily activities, however some individuals lose their hands
due to amputation caused by accident, or disease. Prostheses are assistive devices that help
people with disabilities fulfill their needs. Research was conducted to determine the direction
of carbon fiber on mechanical strength using the filament winding method between carbon fiber
reinforcement and polylactic acid (PLA). The carbon fiber orientation variations used were 65°
and 90°. Mechanical strength evaluation was conducted through tensile test, bending test, and
compression test, as well as ANSYS simulation for deformation and stress analysis of the finger
prosthetic design. The tensile test showed that the flat specimen with 65° orientation had the
highest tensile strength of 24.26 MPa, while the 90° angle reached 22.85 MPa. For the tube
specimen, the tensile strength at 65° angle was 19 MPa and at 90° angle was 15.39 MPa. The
bending test produced the highest flexural strength in the flat specimen with a 90° angle of
187.38 MPa and a 65° angle of 128.36 MPa. In the tube specimen, the 65° angle produced
225.07 MPa and the 90° angle amounted to 314.54 MPa. The compression test showed the
highest strength at a 90° angle of 125.35 MPa. ANSYS simulation showed the highest
deformation in the distal part of all fingers, with the highest stress value of 65.977 MPa in the
index finger and the highest strain of 0.0974 in the middle finger. These results show that carbon
fiber orientation significantly affects the mechanical properties of the material, as well as the
simulation results on the finger prosthetic design.

Tangan memiliki peran penting dalam aktivitas sehari-hari, namun beberapa individu
kehilangan tangan akibat amputasi yang disebabkan oleh kecelakaan, atau penyakit. Prostesis
adalah alat bantu yang membantu penyandang disabilitas memenuhi kebutuhan mereka.
Penelitian dilakukan untuk mengetahui arah serat karbon terhadap kekuatan mekanik
menggunakan metode lilitan filamen antara penguat serat karbon dan polylactic acid (PLA).
Variasi orientasi serat karbon yang digunakan adalah 65° dan 90°. Evaluasi kekuatan mekanik
dilakukan melalui uji tarik, uji bending, dan uji kompresi, serta simulasi ANSYS untuk analisis
deformasi dan tegangan pada desain prostetik jari tangan. Uji tarik menunjukkan bahwa
spesimen flat dengan orientasi 65° memiliki tensile strength tertinggi sebesar 24.26 MPa,
sedangkan sudut 90° mencapai 22.85 MPa. Untuk spesimen tube, tensile strength pada sudut
65° adalah 19 MPa dan pada sudut 90° sebesar 15.39 MPa. Uji bending menghasilkan flexural
strength tertinggi pada spesimen flat dengan sudut 90° sebesar 187.38 MPa dan sudut 65°
sebesar 128.36 MPa. Pada spesimen tube, sudut 65° menghasilkan 225.07 MPa dan sudut 90°
sebesar 314.54 MPa. Uji kompresi menunjukkan kekuatan tertinggi pada sudut 90° sebesar
125.35 MPa. Simulasi ANSYS menunjukkan deformasi tertinggi pada bagian distal dari semua
jari, dengan nilai tegangan tertinggi 65.977 MPa pada jari telunjuk dan strain tertinggi 0.0974
pada jari tengah. Hasil ini menunjukkan bahwa orientasi serat karbon signifikan mempengaruhi
sifat mekanik material, serta hasil simulasi pada desain prostetik jari.
