The dynamic thermal mechanical properties of Bamboo fiber(BF)/Polylactic Acid(PLA) composites were studied by the thermal dynamic mechanical analyzer (DMA). The results showed that E' and tanδ were affected by mass fraction of BF and coupling agent. Because interfacial compatibility between BF and PLA was poor, the dynamic thermal mechanical properties of composites were bad when coupling agent was...
The fibre-reinforced green composites made from bamboo fibre and biodegraded resin(Polylactic Acid) were fabricated by injection molding, effects of alkali treated bamboo fibres on mechanical properties (tensile strength and impact strength) of fibre-reinforced green composites were studied, and variance of main chemical components of alkali treated bamboo fibres and untreated bamboo fibres was characterized...
Different surface modifiers (stearine acid and titanate coupling agent) were used to modify wood fibers. Effects of surface modified wood fibres on mechanical properties ( tensile strength and impact strength) of fibre-reinforced biodegradable composites were studied,and the tensile fracture surfaces and the interfacial adhesion of composites were examined by scanning electron microscopy,interfacial...
Cement-bonded straw fiber board made from straw fiber and cement was prepared by semi-dry processing technology to investigate the effect of alkali treatment on the mechanical properties of the board. Results indicated that, board fabricated with 1% alkali solution treated fiber showed maximum improvement in mechanical properties. After alkali treatment, hemi-celluloses of straw fiber were removed,...
In order to explore the potential of Phyllostachys pubescens used as resources utilization on biomedical, determination of the chemical components in five-year-old Phyllostachys pubescens was carried out by means of Py-GC/MS. 69 peaks were obtained from Phyllostachys pubesces and 62 compounds which occupy 99.99% of the total peaks areas were identified. The main components in Phyllostachys pubescens...
The pyrolytic products of Dendrocalamusbarbatus organism body is of important value in healing some diseases. Therefore, the determination of the chemical components from the five-year-old Dendrocalamusbarbatus was made by using Py- GC/MS. The results indicated that the main components of the Dendrocalamusbarbatus by Py-GC/MS analysis were carbon dioxide (54.34%), 2-butanamine, (s)- (17.4%), oxirane,...
Bamboo wood especially the Phyllostachyspubescens is extremely abundant in our country, however, the high moisture content and easy to mildew and decay has limits it widely application in solid material. In this study, a novel carbonization with low temperature and non-smoke is introduced, and whole factor analysis method and variance analysis are used to find a novel and optimized process parameter,...
Wood-based composites is widely used in building and interior decoration field. However, it is easy for wood to get burnt, and abundant toxic smoke generating during the burning process has caused great casualties and property loss. In this study, poplar wood was chosen as test materials, and three fire-retardant were selected, i.e. the inorganic X type fire-retardant and the organic fire-retardant...
Bambusa blumeana is the one of the most impotent bamboo species in South China. In order to exploit the high- grade resource utilization as bioenergy, determination of chemical components in Bambusa blumeana was made by using Py-GC/MS. Results indicated that the main components of Bambusa blumeana by Py-GC/MS analysis were carbon dioxide (30.99%), acetic acid (13.67%), tuaminoheptane (9.81%), diazene,...
