. In daily life, expanded polystyrene foams (EPS) are widely used as packaging material and waste EPS has caused lots of environmental pollutions because it cannot be decomposed in nature. In this study, the machining process is developed of a reinforced foam packaging material by hot press molding, potato starch and birch fiber as the main raw materials. Analysis of the dosage of the birch fiber, starch adhesive and foaming agent and how do they affect the mechanical properties. Experiments show that material compressive strength is good and foam well-distributed, when the birch fiber content is 20%-25%, adhesive content is 30%-35%, and birch fiber amount is 10%-15%, the material has fine performance, and the cells are well distribute.

The new type of cushion packaging material that took wood fiber and starch as raw materials was investigated in this paper. Through compression molding, the effects of some parameters on material’s mechanical properties were studied to optimize the technical process, including the ratio of wood fiber to starch, the content of adhesive and foaming agent. Using DPS data processing system for Second-order Polynomial Stepwise Regression to analyze the effects of the different process parameters on the properties and establish mathematical model, so as to optimize the experimental program and ascertain the best conditions, at the same time to verify it. The results show that the ratio of wood fiber to starch is 1:2, 6% AC foaming agent, and 10% polyvinyl alcohol are the optimum parameter.

Foamed materials are widely used, mainly as a protection objects during transport of various products. Traditionally foams are produced from plastics so they are very difficult for waste management. It is the challenge for many scientific centres to develop a technology for the production of bio-based materials which can be rapidly decomposed. The task for the researcher is to obtain a relatively cheap, easy to use and completely biodegradable materials. The aim of this work was the selection of the main raw materials, functional additives and process parameters to obtain the most effective parameters of extrusion-cooking process for foamed starch-based materials. Properties of the products and processing costs were taken into account. During the study, the extrusion-cooking process was performed under various conditions: temperature, humidity, type of the die, screw rotational speed, various raw materials and additives blends. The best results were obtained for mixtures based on potato starch and with addition the foaming agent Plastron foam PDE and poly(vinyl) alcohol PVA.

Optimal Formula

In order to minimize the environmental pollution attributed by traditional plastic packaging material with cushioning performance, a new biodegradable packaging material with cushioning performance was created in the present research. Being made from potato starch, fiber and PVA as well as foaming agent the new product was prepared by a measure of pressure-molding. The impact of each of the four components on the mechanical properties of the product was studied and the optimal formula was determined by a measure of orthogonal test. The results showed that a formula of potato starch 100g, fiber 30g, PVA 40gand foaming agent AC 0.80g gave the product the better mechanical property where tensile strength reached 1.93MPa. Comparing with traditional foamed plastic packaging materials the extension strength of starch-fiber based new product showed 60%-180% higher than EPS’s and 50%-150%higher than EPE’s.

Carbon fabric/phenolic composites modified with potassium titanate whisker (PTW) were prepared by a dip-coating and hot-press molding technique, and the tribological properties of the resulting composites were investigated systematically using a ring-on-block arrangement under different sliding conditions. Experimental results showed that the optimal PTW significantly decreased the wear-rate. The worn surfaces of the composites and the transfer film formed on the counterpart steel ring were examined by scanning electron microscopy (SEM) to reveal the wear mechanisms. The transfer films formed on the counterpart surfaces made contributions to the improvement of the tribological behavior of the carbon fabric composites. The friction and wear of the filled carbon fabric composites was significantly dependent on the sliding conditions. It is observed that the wear-rate increased with increasing applied load and sliding speeds.

Sintering Method

An Fe/FeAl2O4 composite was prepared with Fe-Fe2O3-Al2O3 powder by a hot press sintering method. The mass ratio was 6:1:2, sintering pressure was 30 MPa, and holding time was 120 min. The raw materials for the powder particles were respectively 1 µm (Fe), 0.5 µm (Fe2O3), and 1 µm (Al2O3) in diameter. The effect of sintering temperature on the microstructure and mechanical properties of Fe/FeAl2O4 composite was studied. The results showed that Fe/FeAl2O4 composite was formed by in situ reaction at 1300 °C–1500 °C. With the increased sintering temperature, the microstructure and mechanical properties of the Fe/FeAl2O4 composite showed a change law that initially became better and then became worse. The best microstructure and optimal mechanical properties were obtained at 1400 °C. At this temperature, the grain size of Fe and FeAl2O4 phases in Fe/FeAl2O4 composite was uniform, the relative density was 96.7%, and the Vickers hardness and bending strength were 1.88 GPa and 280.0 MPa, respectively. The wettability between Fe and FeAl2O4 was enhanced with increased sintering temperature. And then the densification process was accelerated. Finally, the microstructure and mechanical properties of the Fe/FeAl2O4 composite were improved.

The scientifically grounded and experimentally confirmed features of formation of stable foam concrete mixes in time are considered. It is shown that the formation of such gas-filled structures is possible only with water content, the value of which is sufficient for wetting the surface of all solid dispersed particles of raw materials, the formation of foam films and the processes of adsorption and chemical hydration of binder particles. It is proved that taking into account the value of the aeration potential of the foaming agent, it is possible to obtain stable foam concrete mixtures of a given density
