Environmentally friendly composites continue to be developed from kapok tree fiber (Ceiba pentandra) with an epoxy matrix. This study aims to characterize the tensile behavior of single fiber and its composite, the pull-out properties of kapok tree fiber, and morphology of the fiber. Kapok tree fibers were varied in the NaOH solution and the AESO polymer. Single fiber tensile test and pull out refer to the ASTM D3379-75 and ASTM E399 standards, respectively. The composite manufacturing method used in this research was the infusion vacuum resin method with reference to the ASTM D638 standard. The results of the tensile test (composite) showed that the kapok bark fiber with the characteristics of NaOH + Coating had a greater tensile strength (197,88 Mpa), than that without treatment and NaOH treatment. Of all the characteristics of the kapok bark fiber, the highest value of the tensile strength was the fiber treated with NaOH + Coating (KNC). The results of fiber morphology showed proved that the NaOH treatment increased the surface hardness by eliminating the bonds of surface crystallinity, topography, water absorption, unit cell structure and fiber orientation. These results indicate that kapok tree fiber treated with 7% NaOH + coating with AESO polymer has high potential as a structural material to replace wood or textile materials.

“…It is speculated that the CHF in these polyester composites has a vital role in impact load resistance. The presence of fibers in the composite has been shown to limit the creation and propagation of cracks from the matrix as well as transmit stress to the entire composite surface [17,18], enhancing the toughness of the…”

The purpose of this study was to look into the performance of a cornhusk fiber (CHF) reinforced polyester composite with pumice powder (PP) as a filler. The influence of varied PP volume fractions on composite tensile, bending, impact, and fracture morphology was studied. Using the hot press process, polyester-CHF composites with varied volume fractions of PP filler, namely 5%, 10%, 15%, 20%, 25%, and 30% wt, were created. The results showed that increasing the PP volume fraction from 5% to 15% enhanced the tensile strength of the polyester-CHF composite. The modulus of elasticity and bending modulus tend to grow when filler Pp decreases from 5% to 30%, but elongation value decreases. Furthermore, the best bending strength and impact toughness of the polyester-CHF composite were produced at a volume fraction of PP filler of 20%. SEM images indicate the presence of CHF pull out in all composite variations as well as the number of voids dependent on the PP filler volume.

Telah diinvestigasi komposit poliester yang dimodifikasi dengan serbuk dari serat hibiscus tiliceus (HT) sebagai inovasi dari material komposit yang baru. Penelitian ini bertujuan untuk menyelidiki sifat mekanik dari komposit dari serbuk hibiscus tiliaceus (HT) setelah direndam dalam larutan alkali dalam periode berbeda. Sebelum dibuat komposit, serbuk HT direndam dalam alkali NaOH 5% selama waktu berbeda yaitu 2, 4 jam, 6 jam, dan 8 jam. Teknik pembuatan komposit dilakukan dengan teknik hand lay-up; resin poliester sebagai matrik dengan hardener dari metil etil keton peroksida 1% dicampur, kemudian dituang ke dalam cetakan dan diberi tekanan 5 MPa selama 12 jam. Sifat kekuatan tarik, modulus elastisitas dan kekuatan bending telah dievaluasi. Hasil studi menunjukkan bahwa lama perendaman serbuk HT dalam NaOH memberikan efek pada sifat mekanik dari komposit serbuk HT/polyester. Setelah serbuk direndam dalam NaOH selama 2 jam, 4 jam dan 6 jam, kekuatan tarik dan bending dari komposit meningkat yang dikaitkan dengan ikatan interface antara serbuk HT-poliester bertambah kuat, tetapi kekuatannya menurun setelah serbuk direndam selama 8 jam karena serbuk HT rusak dan pullout. Analisa SEM menunjukkan morpologi patahan yang rapat dan padat antara serbuk dan poliester serta adanya serbuk HT pullout. Ditinjau dari kekuatan tariknya, komposit yang dihasilkan ini dapat menjadi alternatif pengganti komposit serat gelas. A polyester composite modified with powder from Hibiscus Tiliceus fiber as a new composite material. This study aims to evaluate the mechanical properties of the composite of Hibiscus tiliaceus (HT) powder after being immersed in an alkali solution for different periods. Before making the composite, the HT powder was immersed in 5% NaOH for times; 2, 4, 6, and 8 (hours). The composite manufacturing technique has been carried out using the hand lay-up technique; polyester resin as a matrix with a hardener of 1% methyl ethyl ketone peroxide mixed, then poured into molds and under the pressure of 5 MPa for 12 h. The properties of tensile strength, modulus of elasticity, and bending strength have been evaluated through tensile and bending tests. The results showed that the tensile and bending strengths of the composite increased after the HT powder was soaked from 2 h to 6 h; it is due to an increase in the interfacial bond between the HT powder-polyester, but the composite strength decreased after the powder was soaked for 8 h because the HT powder was damaged and powder pullout occurs. SEM analysis shows a tight and dense interface between the powder and polyester and the presence of HT powder pullout. In terms of tensile strength, the resulting composite can be an alternative to glass fiber composites.
