Special Issue Information

Dear Colleagues,

This Special Issue on ‘Sustainable Natural Materials for Engineering Applications’ addresses the latest progress in the science and technology of natural material applications. Their recent increase in relevance in modern industry and science results from global industrial development, but also from efforts to protect the natural environment, including the implementation of energy-saving solutions and clean technologies. This Special Issue of Materials focuses on current scientific and technological progress in the manufacturing of natural materials and products. Topics of interest include the mechanical and structural properties of composites and their constituent materials; experimental and theoretical studies relating to composites; the manipulation of properties through manufacturing and processing; modeling and simulations; microscopic and macroscopic behavior; and performance verification techniques. This collection will be a source of new ideas for the design, research, and use of sustainable natural materials in engineering applications.

The purpose of the present article is to study the bending strength of glulam prepared by plane tree (Platanus Orientalis-L) wood layers adhered by UF resin with different formaldehyde to urea molar ratios containing the modified starch adhesive with different NaOCl concentrations. Artificial neural network (ANN) as a modern tool was used to predict this response, too. The multilayer perceptron (MLP) models were used to predict the modulus of rapture (MOR) and the statistics, including the determination coefficient (R2), root mean square error (RMSE), and mean absolute percentage error (MAPE) were used to validate the prediction. Combining the ANN and the genetic algorithm by using the multiple objective and nonlinear constraint functions, the optimum point was determined based on the experimental and estimated data, respectively. The characterization analysis, performed by FTIR and XRD, was used to describe the effect of the inputs on the output. The results indicated that the statistics obtained show excellent MOR predictions by the feed-forward neural network using Levenberg–Marquardt algorithms. The comparison of the optimal output of the actual values obtained by the genetic algorithm resulting from the multi-objective function and the optimal output of the values estimated by the nonlinear constraint function indicates a minimum difference between both functions.
