“…The ability of a material to resist deformation under loads is called its flexural modulus. This is measured by how stiff the material is when a force is applied perpendicular to the long edge of a sample [ 23 ]. Heimbach et al [ 22 ] and Ferri et al [ 24 ] also confirmed that the flexural modulus increased (stiffness increased greatly) as the HA content increased.…”

“…As a result, HA and its polymer-based composites have seen widespread use in orthopedic and dental applications. In addition, these biocomposites have important applications in drug delivery, cell and porous scaffolds for tissue engineering, bone screws, prostheses, bone graft, cardiovascular implants, cell culture substrates, spinal cages, anchors, vascular grafts, sutures, skin and tendon healing, antimicrobial agents, cancer therapy, and medical tools [ 11 , 12 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ].…”

Recently, there has been an increase in the number of studies conducted on the process of developing hydroxyapatite (HA) to use in biocomposites. HA can be derived from natural sources such as bovine bone. The HA usage obtained from green mussel shells in biocomposites in this study will be explored. The research goal is to investigate the composition effect of biomaterials derived from polycaprolactone (PCL), polylactic acid (PLA), as well as HA obtained from green mussel shells with a chemical blending method on mechanical properties and degradation rate. First, 80 mL of chloroform solution was utilized to immerse 16 g of the PLA/PCL mixture with the ratios of 85:15 and 60:40 for 30 min. A magnetic stirrer was used to mix the solution for an additional 30 min at a temperature and speed of 50 °C and 300 rpm. Next, the hydroxyapatite (HA) was added in percentages of 5%, 10%, and 15%, as well as 20% of the PLA/PCL mixture’s total weight. It was then stirred for 1 h at 100 rpm at 65 °C to produce a homogeneous mixture of HA and polymer. The biocomposite mixture was then added into a glass mold as per ASTM D790. Following this, biocomposite specimens were tested for their density, biodegradability, and three points of bending in determining the effect of HA and polymer composition on the degradation rate and mechanical properties. According to the findings of this study, increasing the HA and PLA composition yields a rise in the mechanical properties of the biocomposites. However, the biocomposite degradation rate is increasing.

“…Untuk menjawab permasalahan tersebut, berbagai penelitian terus dikembangkan dalam upaya mensubstitusi penggunaan serat sintetis dengan serat alam pada komposit, dikarenakan jumlah serat alam yang berlimpah dan harganya yang relatif murah [5][6][7]. Selain itu, serat alam memiliki berat jenis yang rendah dan sifat mekanis yang cukup baik dalam aplikasi sebagai rompi tahan peluru [8] Ning, H. telah melakukan penelitian mengenai pembuatan komposit polietilen dengan serat kenaf yang dapat memiliki peningkatan kekuatan tarik yang cukup signifikan [9]. A.M.R Azmi telah melakukan uji balistik terhadap material yang sama, namun hasil uji balistik menunjukkan perlu adanya peningkatan kualitas material untuk mampu sepenuhnya menahan penetrasi peluru [10].…”

Rompi tahan peluru sebagai perlindungan diri personel militer umumnya berbahan dasar komposit berpenguat serat sintetis. Komposit berpenguat serat kevlar dan karbon telah mampu menahan laju penetrasi peluru dan memiliki karakteristik ringan, namun biaya produksi dengan serat sintetis tersebut relatif mahal. Penggunaan material substitusi dari serat alam sangat potensial, dikarenakan jumlah serat alam yang berlimpah, ringan, dan harganya yang relatif murah. Salah satu serat alam yang potensial adalah serat dari pelepah salak. Penelitian ini berfokus pada pengaruh penambahan serat pelepah salak terhadap karakteristik komposit serat Kevlar dan serat karbon, dengan filler SiC dan Al2O3. Pembuatan komposit ini dilakukan dengan metode Vacuum Assisted Resin Transfer Molding (VARTM). Terdapat 4 variasi fraksi volume serat dan filler sebagai penguat yang ditambahkan pada komposit ini. Dari hasil pengamatan dengan SEM didapatkan hasil matriks dan penguat sudah terikat dengan baik. Hasil uji balistik menunjukan seluruh variasi sampel uji dapat menahan laju peluru sehingga tidak tembus. Hasil uji mekanik menunjukkan saat ini penambahan serat pelepah salak belum secara signifikan meningkatkan sifat mekanis komposit tersebut

“…The material was able to bounce back bullets launched at speeds of up to 105 m/s, indicating that the designs allowed it to absorb some impact energy. However, because ballistic testing utilise bullets that travel faster than high-velocity impact tests, the materials must still be improved before they can be used as a material for ballistic-resistant panels [ 192 ]. For similar purposes, Petre et al studied novel polyurea-based composite materials (PUCs) and fibre-reinforced polymer composites for military applications, such as reducing blunt trauma for ballistic protection equipment in terms of thermal and mechanical properties and ballistic protection.…”

Physical, Mechanical and Perforation Resistance of Natural-Synthetic Fiber Interply Laminate Hybrid Composites

et al. 2022

View full text Add to dashboard Cite

Natural and synthetic fibres have emerged in high demand due to their excellent properties. Natural fibres have good mechanical properties and are less expensive, making them a viable substitute for synthetic fibers. Owing to certain drawbacks such as their inconsistent quality and hydrophilic nature, researchers focused on incorporating these two fibres as an alternative to improve the limitations of the single fibre. This review focused on the interply hybridisation of natural and synthetic fibres into composites. Natural fibres and their classifications are discussed. The physical and mechanical properties of these hybrid composites have also been included. A full discussion of the mechanical properties of natural/synthetic fibre hybrid composites such as tensile, flexural, impact, and perforation resistance, as well as their failure modes, is highlighted. Furthermore, the applications and future directions of hybrid composites have been described in details.
