Investigation of Mechanical Behavior of Polymeric Foam Materials Reinforced by Oil Palm Empty Fruit Bunches (Opefb) Fibers Due to Static and Dynamic Loads

Abstract

Polymeric composite foam with EFB fiber reinforced is new material that can be utilized as an alternative engineering material. EFB fiber utilization becomes the center of subject in this research. Moreover, these composites are unique with the presence of cavities (foam) in the matrix of unsaturated polyester resin. It results a decrease in density of the material that formed, and obtain a thermoset polymer composite material lighter than any else similar type. The objective of this study is to obtain the best manufacturing techniques of composite material, the mechanical behavior of these materials due to tensile static loading and high strain rate impact, and the distribution of foam that occur in the material that formed as a result of blowing agent (BA) from the type of polyurethane (PU). In this research, the sample formed into standard specimen of testing, such as ASTM D638 for static tensile test, and impact test specimen. Mechanical’s behaviors that are obtained in this research are density, tensile strength, modulus of elasticity (E), the incident stress, and dynamic modulus of elasticity of the material. For static testing was performed according to standard ASTM D638 tensile and impact test using the Kolsky’s method. To know the distribution of foam that occur in the material, were observed using Scanning Electron Microscope instrument (SEM). To determine the stress distribution in this material, then conducted a computer simulation using Ansys. The best result obtained by the composition of this material based on material composition, which resin consumption can be reduced by the presence of BA as well as mechanical strength, good enough for molding. The best composition in this study will be used in subsequent studies, namely the design and manufacture of traffic cones from this material.

Numerical Analysis of Polymer Foam Composite Material (PFCM) Reinforced by Palm Empty Bunch Fiber (PEBF) at Fracture Point Due to High Strain Impact Load

“…Rosma Bana Utama, Medan, Indonesia. The sample composition used based on the research of Zulfikar et al (Zulfikar, Umroh and Siahaan, 2019) is: 20% foam generator, 60% resin, 10% catalyst, and 10% PEBF, and the number of specimens tested is as many as 15 samples.…”

“…Based on these results, the highest tensile stress and modulus obtained in the composition 7PEFB: 3SCB with a value of 5.56 MPa and 661 MPa. Zulfikar et al (Zulfikar, Umroh and Siahaan, 2019) have examined the properties of this material due to high strain rate impact loads. The results obtained are the magnitude of the impact stress data distribution in the test of 15 samples ranging from 12-17 MPa with an average value of 13.8 MPa.…”

Desain dan Pembuatan Cetakan Papan Tiruan Metode Cetak Tekan

“…Beberapa ahli telah mendefinisikan pengertian tentang desain produk. Adapun pengertian dari desain produk menurut Suyadi Prawirosentono dalam bukunya Manajemen Produksi ialah desain produk merupakan rancang bangun dari suatu produk (barang) yang akan diproduksi [19]. Franklin G Moore dan Thomas E Hederick dalam bukunya Manajemen Produksi dan Operasi mengatakan bahwa desain produk merupakan hal yang paling penting, karena kesempatan yang dimiliki produk baru sering menakjubkan.…”
