“…This phenomenon might be attributed to the microorganism activities on the film surface, which later revealed the SPNFCs images that adhere within the film. Therefore it can be summarized that natural fibers and biopolymers have attracted considerable attention of scientist and industries due to their sustainable nature and environmentally friendly [54][55][56][57][58].…”

This paper aims to study the degradation rate of sugar palm nanofibrillated cellulose (SPNFCs) and sugar palm starch (SPS). SPNFCs were isolated from sugar palm fiber, while SPS is extracted from sugar palm trunk. The SPNFCs were reinforced with SPS biopolymer as biodegradable reinforcement materials of different diameter/length based on the number of passes of high pressurize homogenization process (5, 10 and 15 passes represented by SPS/SPNFCs-5, SPS/SPNFCs-10, and SPS/SPNFCs-15). These SPNFCs were incorporated into SPS plasticized with glycerol and sorbitol via solution casting method. Soil burial experiment performed on SPS and SPS/SPNFCs bionanocomposites showed that SPS was degraded more rapidly by losing 85.76% of its mass in 9 days compared to 69.89% by SPS/SPNFCs-15 bionanocomposite. The high compatibility between SPNFCs nanofiber and SPS biopolymer matrices can be observed through field emission scanning electron microscopy (FE-SEM). Degradacja i właściwości fizyczne bionanokompozytów skrobi palmy cukrowej wzmocnionej nanowłóknami celulozowymi tej palmyStreszczenie: Zbadano szybkość degradacji nanowłóknistej celulozy wyizolowanej z palmy cukrowej (Arenga pinnata) (SPNFCs) oraz skrobi wydzielonej przez ekstrakcję z rdzenia pnia tej palmy (SPS). SPNFCs uzyskiwano z włókien palmy cukrowej, poddawanych homogenizacji pod wysokim ciśnieniem w 5, 10 lub 15 cyklach, otrzymując nanowłókna celulozy o różnej długości i średnicy. SPNFCs wprowadzano do SPS uplastycznionego mieszaniną (1 : 1) glicerolu i sorbitolu. Metodą odlewania z roztworu wytwarzano błony nanokompozytowe SPS/SPNFCs-5, SPS/SPNFCs-10 i SPS/SPNFCs-15. Test glebowy procesu biodegradacji wykazał, że SPS ulegało szybszej degradacji, tracąc 85,76% swojej masy w ciągu 9 dni, w porównaniu z ubytkiem masy 69,89% w wypadku bionanokompozytu SPS/SPNFCs-15. Na podstawie analizy metodą skaningowej mikroskopii elektronowej z emisją polową (FE-SEM) stwierdzono dużą kompatybilność między nanowłóknami SPNFCs i biopolimerową osnową SPS.Słowa kluczowe: palma cukrowa, homogenizacja wysokociśnieniowa, nanowłóknista celuloza, nanokompozyty, degradacja w glebie.Nowadays, total biodegradable green composite or biocomposite, which are made up of natural matrices and natural fibers, have attracted many researchers for the advantages they offer. The major factors contributing to the increase of interest include the rise in petroleum prices and the inevitable environmental pollution contrib-1)

“…Many of the studies on material selection in automotive application ignore the composition of the materials. Their considerations are only the design criteria, environmental issues and customer requirements [40,41,56,57]. A recent study on material selection using statistical analysis used a single model to examine natural fibre and the polymer matrix [45,46].…”

Material selection has become a critical part of design for engineers, due to availability of diverse choice of materials that have similar properties and meet the product design specification. Implementation of statistical analysis alone makes it difficult to identify the ideal composition of the final composite. An integrated approach between statistical model and micromechanical model is desired. In this paper, resultant natural fibre and polymer matrix from previous study is used to estimate the mechanical properties such as density, Young's modulus and tensile strength. Four levels of fibre loading are used to compare the optimum natural fibre reinforced polymer composite (NFRPC). The result from this analytical approach revealed that kenaf/polystyrene (PS) with 40% fibre loading is the ideal composite in automotive component application. It was found that the ideal composite score is 1.156 g/cm 3 , 24.2 GPa and 413.4 MPa for density, Young's modulus and tensile strength, respectively. A suggestion to increase the properties on Young's modulus are also presented. This work proves that the statistical model is well incorporated with the analytical approach to choose the correct composite to use in automotive application.

This-study is focused on a-conceptual-design of a-kitchen-appliances/utensils-set, comprising of five-color-coded food-chopping-boards and five-matching-color-coded-knifes, to-reduce cross-contamination at private-homes, aswell-as at food-establishments. Selected-relevant-Patents, as-well-as products, available locally and internationally, were analyzed. The-Joseph-Joseph Index™ Color-Coded Chopping-Boards set (of four), was chosen as a-point of reference for the-current-design; its-seven-identified-limitations have-directed the-scope of the-current-design. Target-specifications/objectives, of the-set, were formulated from the-document-analysis, while Pair-wise-Comparison-Charts were-used, to-rank the-importance of the-objectives, in the-different-levels. The-best-rankeddesign (out of the-four-alternatives made) was chosen, via standard Engineering-Design Weighted-Decision-Matrix (EDWDM) and 'Drop and Re-vote' (D&R) method. 2D-drawings, of the-best-design-alternative, were created via computer-aided-design (CAD) AutoCAD-software 2018, while 3D-modeling, of the-set and all-itscomponents, was produced by Autodesk-Inventor-Version: 2016 (Build 200138000, 138). Designed-labels (positioned on each-board and each-knife, as-well-as on the-set itself, as an-inclined-panel) were introduced, tocater for the-people with color-blindness (according to-the-fundamental-principles of the-Universal-design), and also to-avoid-confusion (as a-reminder which board is which) for all-users. The-study adopted 'analysis' method of materials-selection. The-main objectives, of the-intended-set, was used as a-guide, in-preliminary-materialsselection. This-concise-study has focused on conceptual-design only; and, hence, it-is further-recommends to: (i) carry-out a-detailed-design; (ii) select a-specific-material (out of the-group, identified by this-study); (iii) choose a-mode of fabrication of the-set; (iv) examine the-possibility of incorporating of anti-microbial-agent(s) and/or coating(s); (v) fabricate the-prototype(s); (vi) conduct explorative-use-ability-trials; and (vii) analyze themarketing-aspect of the-final-set. This-work is potentially-beneficial-to engineering-product-design students and faculty, as-well-as to-households and food-establishments (subject-to successful-implementation).
