Mechanical And Physical Properties

Carbon fibres are leading reinforcements in composite materials because of their outstanding mechanical and physical properties. However, the graphitic surface of these fibres is relatively inert, and the weak interaction between the carbon fibres and the polymeric matrix has negative consequences for the mechanical properties of composite materials. Surface treatments have been used to increase the surface roughness, remove contaminants or weakly bonded layers, and to alter the surface chemistry and wettability of the fibres. In this article, the authors review the effect of the microstructure on the response of the carbon fibres to the surface treatments. The observations from conventional carbon fibres and functionalisation techniques are extrapolated to plasma surface treatments and to novel carbon fibres produced from bio-precursors.

Reinforced Composite

Today we are facing a great problem due to the synthetic compounds, as most of them are not environmentally friendly. Natural fibers are the fibers which are obtained from the nature and these fibers are environment friendly. So the use of natural fiber is increasing day by day in different sectors. But natural fiber has some limitations for widely use, one of them is the hydrophilic nature. So it cannot be widely used. That is why we need to incorporate them with low mechanical property synthetic compounds, widely known as composite materials. When we are using natural fiber with polymeric materials by forming composites, the fiber properties greatly influence the strength or mechanical properties. So researchers are trying to reduce this weakness of the natural fiber reinforced composite materials. One of the widely used methods for the improvement of tensile properties is the application of radiation (gamma and UV). The control use of gamma and UV-radiation increases the tensile properties in some extent for the use of materials in practical applications. The reason of this increment in tensile properties is the high energy radiation making crosslink among the molecules. In all the respect of fiber reinforced composite highest tensile properties are observed at a certain dose of gamma and UV-radiation.

This article focuses on the development of phenolic resin moulding materials for the production of new carbon fibre-reinforced ceramic composite materials based on C/C-SiC by utilising the LSI (liquid silicon infiltration) production method. The production of these moulding materials is being accomplished by combining phenolic resin and carbon fibres with the addition of a few selected parts of processing aids, during which the influence of the used lubricants on the processability of the moulding materials is examined. The starting materials, microstructures and mechanical properties of the materials were characterised at every step of the entire process (CFRP and C/C composites) as well as the end of the whole production (C/C-SiC composites). During this investigation a link between the portions of the lubricant used, the forming of the porosity and the impact on the mechanical properties was discovered. In regards to the optimisation of the process the involved parties were able to determine an optimal lubricant ratio.

Pyrolysis Process

Abstract The article deals with the influence of thermal pyrolytic degradation on mechanical properties of carbon fibres used in the production of composite material. The carbon fibre has been chosen as the reinforcement of composite and the resin formed a matrix (binder). During the pyrolysis process, the resin was eliminated and the carbon fibre was separated. Pyrolysis was carried out at temperatures of 450 °C, 550 °C and 650 °C. Subsequently also tensile tests were performed on the treated material to compare the mechanical properties of the fibres prior to pyrolysis and after decomposition. The results showed negative influence at the selected temperatures during the pyrolysis treatment on the mechanical properties of the carbon fibres.
