Characteristics of Composite Flour (Biang fish Ilisha elongata and Sago) For the Development of Good Nutritional Food Products

Composite flour is a mixture of fish flour and sago flour to increase nutrition in food products. This study aims to increase the nutritional value of food products with sago flour as raw material. Composite flour from fish and sago flour were 0%, 2%, 4%, 6%, 8%, and 10% Biang fish to the amount of sago flour. The results of the research on fish flour Ilisha elongata showed a yellowish-white color with a whiteness degree of 75.8%. Fish flour has a yield of 28.9% with a fineness level on a 100-mesh sieve. The results show the characteristics of the composite flour of Biang fish and sago, respectively, the color of the flour was white-gray to cream color; having nutritional characteristics, respectively, the moisture content is 9.62%; 9.57%; 9.55%; 9.42%; 9.26%, and 9.20%. The protein content was 0.25%; 3.58%; 4.09%; 4.99%; 5.98%, and 6.39%. The fat content was 0.41%, 0.24%, 0.29%; 0.37%; 0.40%; 0.42%. The ash contained 0.27%, 0.34%, 0.50%, 0.57%, 0.69%, and 0.76%. The carbohydrates were 89.45%; 86.27%; 85.57%; 84.65%; 83.67%, and 83.23%. The calcium content was 1130 mg/kg; 1901 mg/kg; 2687 mg/kg; 2770 mg/kg; 2827 mg/kg and 2869 mg/kg. The addition of fish flour can increase the nutritional value of composite flour made from sago flour and has the potential to develop nutritious food products.

ROLE OF THE E-LEARNING COURSES FOR CAPACITY BUILDING IN THE FIELD OF ADVANCED MATERIALS DEVELOPMENT

This work presents several aspects concerning the e-learning courses about composite materials developed for capacity building in the field of advanced materials for new or upgraded research centers in Morocco and Jordan. The proposed course for capacity building in the field of advanced materials development is represented by 3D advanced composites obtained through textile technologies and additive manufacturing processes. This course presented using e-learning technologies received increased interest from students attending the learning sessions in the framework of the Fostex Erasmus+ project because can be applied to obtain composites for a large area of industries such as automotive, construction, medicine, electronics/electrotechnical and aerospace. The textile composites are materials made from 2/more constituent materials with different chemical, physical and electrical properties. When combined, these materials generate a material (composite) with different characteristics than the initial individual components. The design and development of the composite can lead to new materials with superior characteristics: more robust, lighter, flexible, and less expensive in comparison with traditional materials such as metal, ceramics.

Effects of wood flour and MA-EPDM on the properties of fused deposition modeling 3D-printed poly lactic acid composites

Fused deposition modeling (FDM) 3D printing technology is the most common system for polymer additive manufacturing (AM). Recent studies have been conducted to expand both the range of materials that can be used for FDM and their applications. As a filler, wood flour was incorporated into poly lactic acid (PLA) polymer to develop a biocomposite material. Composite filaments were manufactured with various wood flour contents and then successfully used for 3D printing. Morphological, mechanical, and biodegradation properties of FDM 3D-printed PLA composites were investigated. To mitigate brittleness, 5 phr of maleic anhydride grafted ethylene propylene diene monomer (MA-EPDM) was added to the composite blends, and microstructural properties of the composites were examined by scanning electron microscopy (SEM). Mechanical strength tests demonstrated that elasticity was imparted to the composites. Additionally, test results showed that the addition of wood flour to the PLA matrix promoted pore generation and further influenced the mechanical and biodegradation properties of the 3D-printed composites. An excellent effect of wood flour on the biodegradation properties of FDM 3D-printed PLA composites was observed.

An integrated decision-making model for wind turbine blade material

Wind turbines are the devices used to harness wind energy. The turbine blades are one of the components which directly confront the wind and convert it into mechanical energy. Various material composites are used in the turbine industries to manufacture wind turbine blades but it is hard to select the best material composite along with the choices. In this study, an MCDM technique named Measurement of Alternatives and Ranking according to Compromise Solution (MARCOS) method is applied to select the best material composite among the set of materials for manufacturing of the blades. The weights of the criteria are determined by the Best Worst (BWM) method. Around 9 criteria such as the ultimate tensile strength, stiffness, cost of the materials, panel stability parameter of the material etc. are used to rank the best alternative among the blade materials. The carbon fibre reinforced plastic is seen to be the best material among the other materials composite by applying the MARCOS method.
