“…Impact energy on fiber volume fraction 20% HTBF, with variations in fiber configuration 0 0 /0 0 /45 0 /-45 0 /0 0 /0 0 ; 0 0 /45 0 /0 0 /0 0 /-45 0 /0 0 ; 45 0 /0 0 /0 0 /0 0 /0 0 /-45 0 , respectively: 18.67, 18.68, 18.68 J, impact toughness respectively: 0.113, 0.113, 0.112 J/mm 2 . What influences the energy and impact toughness of polyester composites with HTBF reinforcement is the variation in the volume fraction of HTBF natural fiber, in line with the results of the study (Bakri et al, 2022). The composite samples were tested by the tensile and water absorption tests.…”

This study aims to determine the effect of seat direction configuration on changes in impact energy and toughness. The specimen is a polyester composite material reinforced with Hibiscus tiliaceus bark fiber (HTBF). HTBF is given alkali treatment by soaking in 5% NaOH solution for 6 hours. The test specimens were made using the hand layup method, using a total of six fiber layers with varying fiber direction configurations

“…For coconut coir fiber composite, the maximum stress of 17%, 22% and 27% volume fraction are 16.46 MPa, 20.16 MPa and 26.33 MPa respectively and the maximum strain is 0.11, 0.20 and 0.13 respectively. Furthermore, the results of the tensile test experiment are used to model the material in numerical simulations [17] [18].…”

This paper aims to investigate the ballistic performance of metal-coir fiber composite laminate with the variation of fiber volume fraction. the experimental and simulation methode was used to analysis the ballistic performance. The variation of fiber volume fraction in coir fiber composite are 17%, 22%, and 27%. Composite laminate was produced by 3 layers including metal plate on the outer layer and coir fiber composite on the middle layer (core), and metal (steel) plate on the back. The experimental and numerical simulation results show that the fiber volume fraction of coir fiber composite in composite laminate causes unequal impact yield characteristics. The bullet projectile pushes and forms a crater in the first layer steel plate as a result of plastic deformation. The coir fiber composite in the second layer experienced delamination with the failure in the matrix, as a result of bullet impact and damage to the composite surface. The metal plate on the third layer of the laminate is pushed in the direction of the bullet producing a bulge. The effect of the volume fraction of the coir fiber composite as a layer for energy absorption is very effective so that the stress distribution is not directly transmitted to the third layer steel plate. The results of experimental tests and numerical simulations of steel plate-coir fiber composite laminate with a volume fraction of 27% which is influenced by bullet speed are able to stop bullets faster at 5.75×10−5 s with an energy absorption of 435.6 Joule. The failure mechanism that occurs from the results of experimental testing and numerical simulations is the formation of a crater in the first steel plate with the presence of petals formed around the crater and the occurrence of intralaminar failure in the composite and the formation of bulges in the third layer of metal plate due to ballistic deformation.
