Synthetic glass and jute fabric reinforced soy-based biocomposites: Development and characterization

In this work, both glass fabric and jute fabric reinforced nanoclay modified soy matrix-based composites were developed and characterized. Glass fabric (60 wt.%) reinforced composite showed maximum tensile strength of 70.2 MPa and thermal stability up to 202°C, which are 82.8% and 12.2% higher than those observed with corresponding jute composite. Water absorption and contact angle values of glass-soy specimens were tested, and found composites are water stable. Biodegradation study of composites under soil burial condition revealed that glass-soy composite with 40 wt.% glass fabric lost maximum 32.6% of its original weight after 60 days of degradation. The developed glass fabric-soy hybrid composites with reasonable mechanical, thermal, and hydrolytic stability can be used in different sectors as an alternative to the nondegradable thermoplastic reinforced glass fabric composites.

Research of High-Frequency Magnetotelluric Sounding in Mineral Resources Exploration in Northern Guangxi, China

In the mountains area, we have to solve the problem that how to select appropriate method, accurately and effectively explore the burial condition and location of the deep mineral ore with complex terrain. Advanced and Convenient high-frequency magnetotelluric (HF-MT) sounding system Stratagem EH- 4 was applied to electromagnetic array profile survey in target mining area of northern Guangxi. Bostick and Rapid Relaxation Iterative inversion method were used to interpret the observational data, and it has been verified by the mine works that location of faults and orebodies marked by resulting images are tally with the real geological conditions, which provide resource base for the continued production of the mine. This measurement technique and interpretation method should be popularized and applied in mineral resources exploration, especially in mountains area.
