Courtaulds AS carbon fibres have been studied by the ESCA technique after oxidation treatments in a mixture of H 2SO 4 and HNO 3 to increase the amount of oxygen containing groups on the fibre surface. The elements C, O, N, S, Cl, Na, Ca and Si were observed within the fibre ...
Cotton, being a natural fibre, contains more natural impurities on its primary and secondary walls. Analysis of cotton wax, in the past, has revealed a general composition as 25% fatty acids, 52% alcohols, 10% sterols, 7% hydrocarbons an... D Saravanan,N Govindaraj,P Harish - 《Indian ...
The waste carbon fibre reinforced composite plastic sample consisted of a polybenzoxazine resin backbone (a phenolic-type thermoset). The composite consisted of approximately 61.5 wt% carbon fibre and 38.5 wt% resin. The elemental (CHNOS) composition of the carbon fibre reinforced plastics was, 80.3...

In practice, it is very challenging to investigate a material's composition and structure simultaneously, which requires spectroscopic capabilities in situ with ultrahigh-resolu- tion microscopy tools, especially when the functioning unit is within nanometric scale. For example, the electronic and ...
Natural materials are a focus for development of low carbon products for a variety of applications. To utilise these materials, processing is required to m
The chemical composition of 51CrV4 spring steel used for high-speed train bogie was designed using orthogonal test method.Effects of main alloying elements C,Mn and Cr on mechanical properties of 51CrV4 spring steel were studied,which resulted in determination of an optimum chemical composition ran...

(UV) light. The network composition involved incorporating an oxetane-substituted chitosan precursor into a two-component polyurethane system. When subjected to mechanical damage, the four-member oxetane rings within the network opened, generating two reactive ends. Subsequent exposure to UV light ...
The specific pulping conditions (e.g., time, temperature, pH) used to extract unbleached fibers from the biomass can strongly influence the chemical composition (e.g., carbohydrate and lignin content), structure (e.g., degree of fibrillation) and properties (e.g., mechanical and barrier prope...
