Bamboo Fiber Composites Microstructure Design, Preparation And Properties Research

With the basic research on the bamboo fiber structure and properties,characteristics and properties of the selected matrix materials, we use the bamboo fiber and resin matrixes to make variety of bamboo fiber composite materials, then, we given a systematic study on characteristics of the bamboo fiber composite materials by the tensile, compression, bending and impact test research. Found that the mechanical properties of composite materials that we made increase to some certain extent then started to decline when Increase the content of bamboo fiber, this shows that there are mechanical properties peak there. This thesis research has enriched the theoretical system of composite materials.At present, few academic studies for the composite materials of the thermal physical properties, this is the first in the world to get a thermal physical properties mathematical model. Use the model prepared by the typical bamboo fiber composite materials,thermal conductivity, specific heat and other physical properties of typical bamboo fiber composite materials has been tested and theoretical analysis has been given by the author through the model , the results show that the actual measurement data and the theoretical model data are very close to the test data; More unexpected is:This model can predict not only the Thermo-physical properties but also to other non-thermal physical properties such as Poisson's ratio and modulus properties, and it has high consistency as predictive analysis and theoretical calculation results with the actual test results.Since the properties of bamboo fiber composites are relate with many factors that are very complex, so the author introduce the fuzzy theory into bamboo fiber composite materials research and get some fuzzy mathematical models to show the input factors that effect output for the composite material. Authors put forward the design of fiber composite reverse problems and solutions, theoretical models of bamboo fiber composite materials to guide experimental analysis of research and practical engineering applications have achieved good results.In order to guide theoretical research and actual production, Thermal conductivity process in the bamboo fiber reinforced thermosetting resin and thermoplastic resin composites has been analyzed by using finite element method for simulation analysis, and get the heat conduct correlation model.
