Study on Miscanthus Bending Physical Characteristics
Abstract: To cutting down the huge demand on energy and the rely on the fossil oil is the challenge which the world faced. To take advantage of the Miscanthus Biomass is part of bioenergy in the future. This experiment is to use the miscanthus sinensis nurtured by Hunan Agricultural University’s test garden, and to adopt the three-point bending method to finish the Miscanthus sinensis rod bending fracture test. According to the Miscanthus sinensis’ Organizational Structure and the feature of bending to finish the analysis of data list. In order to test the influence which Cross-sectional area of Miscanthus sinensis, growth position and Storage time to breaking force. And then we can get the Physical Characteristics of the bending miscanthus sinensis. So this experiment can provide basic data and theoretical basis on design of processing equipment and improve the technology.
Key words: miscanthus Biomass；miscanthus；organizational structure；bending; Mechanical properties.
