The hot pressing process parameters were optimized to prepare flax fiber reinforced polyethylene (PE) thermoplastic composite by the Taguchi method. The optimal hot pressing process parameters were determined to increase the tensile strength of the composite. The optimal parameters of the design include the following sections: hot pressing temperature, pressure, hot pressing time and coupling agent modification time. An L9 (3*4) orthogonal matrix based on the Taguchi method was created. By means of analysis of signal-to-noise ratio and analysis of variance, the optimal hot pressing process parameters combination was found, compared to the average tensile strength in the nine design experiments, and the tensile strength was improved nearly 10%.

To improve the way of efficient recycling of waste Tetra Pak package, save wood materials and develope new packaging materials, this article studied on the optimum hot-pressing process and surface decoration of waste Tetra Pak/sawdust composite board. Using the orthogonal experimental method, we studied the effect of that four factors, such as resin content, hot-pressing temperature, hot-pressing time and Tetra Pak/sawdust mass ratio, on MOR, MOE, TS for 2h of waste Tetra Pak/sawdust composite board. And according to the measurement and analysis of these three test indicators of the board, we obtained the optimum hot-pressing process of waste Tetra Pak/sawdust composite board. The results showed the optimization of process parameters for the board was that: resin content for 14%, hot-pressing temperature for 150°C, hot-pressing time for 420s and Tetra Pak/sawdust mass ratio for 4:6 were suitable to product this board. At this point, the maximum MOR of the board was up to 23.1MPa, the maximum MOE of the board was up to 2917MPa, the minimum TS for 2h of the board was down to 6.1%. In the processing of PVC surface decoration, by using comparison tests, the results figured out that hot-pressing temperature for 50°C-60°C, hot-pressing time for 10s-20s, hot-pressing pressure beyond 0.02MPa were good for PVC to decorate this kind of board. The formaldehyde emission of this veneer composite board was 0.3mg/L, the surface abrasion resistance of it could reach 900r, besides, its performance of surface pollution resistance has reached the national standard.

In the present work, Taguchi method was employed to optimize tensile strength and hardness of the stir casted Al/RHA composite. The composites were prepared by varying stir casting parameters like stirring time (6, 9, 12 min), stirring speed (100,200,300 r.pm), and weight percentage of RHA reinforcement (6, 9, 12 %). All the experiments were conducted based on plan of experiments (L9 Orthogonal array) generated through Taguchi Technique. The individual influence of each process parameters on the hardness and tensile strength was determined by using analysis of variance. The result implies that the wt. % of RHA reinforcement was found to be a highly influenced parameter followed by stirring time and stirring speed. Finally, confirmation test was done to verify predictive model with the experimental results.

Friction stir welding (FSW) offers significant advantage when compared with fusion joining process such as no shield gas or flux are used, no harmful gases are produced, thereby making the FSW environmentally friendly. In this work, an experimental approach has been used for studying and optimizing the FSW process, applied on AA6082/SiC/10P composite plates. In particular, the effect of process parameters on ultimate tensile strength (UTS) of FSW joint has been investigated. The UTS of FSW joints is affected by FSW parameters. The FSW of the AA6082/SiC/10P composite plates was carried out with different combinations of FSW parameters. The experiments were conducted according to the Taguchi’s L9 orthogonal array. Taguchi method of designing the experiments was used for optimization of the FSW parameters. The signal to noise ratio and analysis of variance were used to determine the effects of FSW parameters on the UTS of the welded joints. The optimum FSW parameters for the maximum UTS were found to be the tool rotation speed of 1800 r/min, the welding speed of 100 mm/min and the tool tilt angle of 2°. UTS increased by 24.5% when FSW was carried out at optimum process parameters as compared to initial FSW parameters. Results have shown good agreement between the predicted and experimental values of UTS. High tensile strength is required for use of FSWed AA6082/SiC/10P composite joints in aerospace industry.

Recently, applications of three-dimensional (3-D) printers have extensively been increased in various industries. Fused deposition modeling process is one of the most widely used 3-D printing methods in this area due to its simplicity, reliability, and the ability to produce complex parts made of thermoplastic materials.

This paper used pattern design, colour design and mold design comprehensively, using compression molding and simulated carving technology, studying a way to realize the pattern simulation of woodiness restructuring decoration. The result showed that it’s feasible to simulate pattern of new woodiness restructuring decoration, and the adornment effect was good. The line of the simulated pattern needed to be smooth. it’s better for the color in per unit area to be less. During the compression molding of board, the key point of decorative pattern simulation was the mould design. As adornment material instead of structural one, the technological parameters such as impregnation, pressure of hot pressing, time of hot pressing process during the process of preparation had a small effect on the adornment of board.
