In the present work, hybrid composites were developed by using polyester waste fibers along with natural origin materials: olive root fibers and coir pitch filler. Such composite panels can be used as a potential alternative for fiber glass sunshade panels and room dividers in buildings. Hybrid composites were fabricated by mixing polyester waste fibers and olive root fibers in different ratios (0:100, 33:67, 67:33 and 100:0). Coir pith micro-particles with an average size of 312 d.nm were used as filler in the polyester matrix at three different levels (0%, 5%, and 10%) of the overall matrix weight. Mechanical properties, e.g., tensile strength, flexural strength and impact strength, thermal properties, e.g., coefficient of linear thermal expansion, thermo-gravimetric analysis (TGA) and environmental properties, e.g., water absorption, loss of density after exposure to weathering were characterized. For comparison purposes, a commercially available fiber glass sunshades sample was also investigated. Mixture design analysis was used to optimize the ratio of all components in the composite. Graphical comparison of experimental results using regression models showed a high degree of correlation. An optimized formulation of composite with an objective of maximization of tensile strength, flexural strength, impact strength and minimization of water absorption, density loss, as well as coefficient of linear thermal expansion, was determined at 70.83 wt%, 15.15 wt%, and 14.01 wt% of polyester waste fibers, olive root fibers and coir pith micro-fillers, respectively. Overall, it can be concluded that the developed hybrid composites from waste fibrous materials can be used as a promising alternative and a value-added application in buildings and construction purposes.

“…Studi penerapan variasi agregat kasar dan halus untuk meningkatkan kuat tarik belah menghasilkan kuat tarik belah maksimum sebesar 3,4 MPa untuk beton agregat kasar dan 2,6 MPa untuk beton agregat halus (Supit, Pandaleke, and Dapas 2016;Zulfikar and Siahaan 2021). Penambahan serat rami pada agregat beton dapat mencegah laju retak optimum sebesar 0,5% dari berat konstruksi, yaitu memiliki kuat tarik belah sebesar 3,268 MPa setelah 28 hari (Nagaraj, Mishra, and Reddy 2020). Selain itu, penelitian dengan menggunakan analisis faktorial pada penerapan serat goni pada beton dengan waktu pengeringan 7, 28, dan 90 hari mengungkapkan bahwa panjang dan volume serat memiliki efek positif pada sifat beton yang mengeras pada masa perawatan awal dan masa perawatan yang diperpanjang (Siregar and Zulfikar 2022).…”

Tujuan studi ini ialah mendapatkan pola kerusakan spesimen beton kolom silinder (BKS) diperkuat komposit laminate jute (KLJ) berdasarkan hasil uji Split Tensile Test (Uji tarik belah), mengetahui fenomena pemberian penguat bahan komposit laminat jute terhadap beton kolom silinder terhadap persentase pola retak (PPR) spesimen, dan menganalisis perbandingan antara kekuatan tarik belah (KTB) dan PPR. Spesimen uji dicetak berdasarkan standar uji ASTM C496 dengan metode Vacuum Bagging. Variasi spesimen terdiri dari 1 hingga 4 lapis KLJ dan satu variasi tanpa selubung KLJ sebagai spesimen kontrol. Pengujian tarik belah menggunakan alat uji UTM dengan masing-masing variasi dilakukan 3 kali perulangan. Pengamatan dan perhitungan PPR dikerjakan dengan bantuan software Adobe Photoshop. Hasil studi menunjukkan bahwa semakin besar nilai KTB maka semakin besar pula PPR yang terjadi. Peningkatan PPR pada masing-masing KTB dilaporkan dalam artikel ini.

This study explores the effect of different graphene contents on the mechanical behaviour, tensile and flexural properties, and the electrochemical performance of cross-layered glass-reinforced aluminium (GLARE) laminates. Results show that the mechanical properties of GLARE with different graphene contents are similar but not identical. The mass fraction of graphene (0 wt.%-1.0 wt.%) is calculated from the total mass of adhesive. As the graphene content increases (0 wt.%-1.0 wt.%), flexural strength peaks in the presence of 0.5 wt.% graphene, but tensile strength continues to increase. When the graphene mass ratio is 1.0 wt.%, the maximum tensile strength is 245.45 MPa. When the graphene mass ratio is 0.5 wt.%, interlaminar shear strength and flexural strength are 19.06 and 260.22 MPa, respectively, which correspond to different span-thickness ratios of 8/1 and 32/1. This graphene mass ratio indicates the best three-point flexural performance of graphene-reinforced GLARE. This study further explains the enhancement mechanism through fracture surface observation. Graphene with a mass ratio of 0.5 wt.% maximises the flexural strength whilst maintaining a strong GLARE electrochemical performance. At scanning speeds of 40, 80 and 100 mV/s, the specific capacitance values are 1.76, 2.47 and 2.88 F/g, respectively. According to quantum tunnelling theory, graphene can form a conductive network when it is dispersed in a resin matrix. This theory reveals the reason why 0.5 wt.% graphene platelet-modified GLARE has good electrochemical properties.
