“…Since, decreasing the size difference between the fiber particles increased the layer compatibility has decreased the delamination effect, and resulted in increased interfacial fiber bonding between the fiber particles in the sandwich composite panel. 44 This present study indicated that modifying the physical structure of the EFB fiber by increasing its fibrillation degree in order to achieve a smaller particle size difference with fine particles of SMS fiber appeared to be critical for fabricating sandwich composite panel. In terms of composite panel properties, it was discovered that the tensile strength of the sandwich composite panel was significantly impacted not only by the degree of fiber network in the face layer, but also highly influence by the compatibility of the EFB fiber in the face layer and the SMS fiber in the core layer.…”

Sandwich composite panel for heat insulation application were fabricated from two types of agricultural biomass waste, the oil palm empty fruit bunch and spent mushroom substrate. These agricultural biomasses are abundant, renewable, and without proper disposal management, might cause massive environmental pollution. This study investigated the effect of fibrillation degree on EFB fiber through the morphology modification to enhance the properties and thermal characteristic of the sandwich composite panel. Fibrillation is a physical changes that occurred on the surface and internal structure of fiber after undergo excessive physical modification by using refiner machine. Higher fibrillation degree could be achieve by narrowing the space area between two disks of refiner which also known as refining gap. In this research, a composite panel was developed from (SMS) and (EFB) fiber via sandwich hot pressing method. One composite sample using raw EFB fiber and three composite sample at fibrillation degree 191.40%, 211.70% and 271.68% were made at density 0.8 g/cm3. Based on result, the morphological structure of EFB fiber improved in term of formation of small fibril formation, larger surface area, optimum fiber length, optimum fiber diameter and better fiber distribution in composite panel. The mechanical properties of composite was obtained at range 2.77–7.21 MPa for tensile strength, 16.61–18.59 MPa for flexural strength, 2.06–3.18 MPa for internal bond and 4.35–15.79 kJ/m2 for impact strength. For physical properties, value of water absorption and thickness swelling were obtained at range 90.34–142.61% and 18.01–44.80%, respectively. Last but not least, the thermal conductivity value of sandwich composite was obtained at range 0.234–0.282 W/m.K. Overall result found that increasing fibrillation degree on EFB fiber at 211.70% able to contribute in improving the mechanical properties, physical properties and thermal characteristic of sandwich composite panel. This research finding suggested that enhancement of fiber morphology using fibrillation degree approach is considered as an alternative eco-friendly method that could be implemented to improve the properties and thermal characteristic of sandwich composite panel.

Pemakaian material insulasi termal pada bangunan menjadi topik penting dalam upaya efesiensi konsumsi energi listrik. Material insulasi termal berbasis serat alam menjadi alternatif dari serat sisntetis yang banyak digunakan sekarang ini. Kestabilan termal material pembentuk menjadi penting untuk diketahui sebagai dasar kelayakan sebagai material insulasi termal. Kayu kelapa sawit (KKS) dan serat rami (SR) mempunyai potensi sebagai bahan baku material insulasi termal dari serat alam. Penelitian ini bertujuan untuk mengkaji stabilitas termal kayu kelapa sawit dan serat rami sebagai bahan baku material insulasi termal berbasis serat alam. Partikel kayu kelapa sawit dan serat rami mendapat perlakuan sebelum diuji. Kayu kelapa sawit direndam dalam air panas 100 0 C selama 30 menit dan serat rami dalam larutan NaOH 5% dengan waktu yang sama. Pengujian thermogravimetric analysis (TGA) dan diferensial scanning clorimetry (DSC) dilakukan untuk mendapatkan karakteristik termal kedua bahan baku. Pengujian dilakukan untuk kedua serat, tanpa, dan dengan perlakuan. Pengujian TGA menghasilkan KKS dan SR dengan perlakuan memiliki kestabilitas termal yang lebih baik dibandingkan KKS dan SR tanpa perlakuan. KKS dan SR dengan perlakuan memiliki kestabilan termal maksimal temperatur 377 0 C dan 399 0 C. Analisis DSC dari KKS dan SR dengan perlakuan memperlihatkan temperatur puncak pada 409 0 C dan 408 0 C. Stabilitas termal serat akan meningkat dengan perlakuan dibandingkan serat tanpa perlakuan.

“…[12,13] While impressive interfacial strength can be obtained (e.g., 6 MPa at PP/glass interface using covalent grafting), [4,5] the chemical modification methods are typically costly. Physical modification methods are being investigated at both the macroscopic level, such as fiber fibrillation [14] and polymer rivet, [15] as well as microscopic level, such as sputter etching [4] and plasma treatment, [16] heat treatment [17,18] , and CO 2 laser treatment. [19] Unfortunately, these physical modification methods lack control of the microscopic features imprinted on the surface, which is an important element of the interfacial bond strength.…”

Fiber reinforced thermoplastic composites are limited due to poor interfacial bonding between the nonpolar/nonreactive polymer matrix and fiber surface.Recently, a concept of controlled mechanical interlocking between fiber and matrix surface was proposed to improve the interfacial bonding in fiber reinforced thermoplastic composites. Study results show promising performance of the approach under static loading conditions. In this work, we study the effect of strain rate on the interfacial bonding behavior under dynamic loading conditions. A parametric study of the strain rate effect is performed for which different surface microarchitectures of a glass/polypropylene composite system are considered. A three network model is implemented for modeling mechanical behavior of polymer, which is calibrated using a set of stress-strain curves experimentally obtained at various strain rates. The strength calcula-
