Carbon Fibre Reinforced Polymers

An investigation of the friction, wear, and mechanical properties of polymers reinforced with different proportions of two types of carbon fibre is described. During dry sliding against steel, coefficients of friction of the composites lie within a common range of 0·25–0·35 at high fibre concentrations, and rates of wear can be reduced by factors of more than 103. Fibre reinforcement can also greatly improve the strength, stiffness, and deformation under load. The most important factor influencing the wear rate is the amount of fibre present: the strength is more dependent on adhesion at the fibre–polymer interface. The practical applications of carbon-fibre reinforced polymers are discussed.

In this study different materials made out of cut-off as well as reclained carbon fibres (rCF) are described and compared. For this benchmark nonwovens, compounds, SMC, BMC, as well as standard lightweight materials like high alloy steels, aluminium and magnesium are taken into account. Specific mechanical properties like modulus and tensile strength are used to show the lightweight potential of recycled carbon fibre materials in ashby charts. It is shown that rCF products can substitute glass fibre applications and are also comparable to metals and alloys.

It is difficult to monitor lightning damage to carbon fibre-reinforced polymers (CFRPs) online. This work experimentally investigates the changes associated with the electrical resistance of CFRPs subjected to lightning strikes. Two kinds of simulated lightning currents with different amplitudes in the range of 10–80 kA were injected into the CFRP samples. By measuring and comparing the changes in the struck-side (front) surface resistance, the surface resistance of the side opposite to the struck-side (back) and the oblique resistance of each sample before and after the lightning strike, it was observed that inflection points exist in the curve of the resistance change rate. The resistance decreases with increasing peak currents before the inflection point and increases when the peak current goes beyond the inflection point. The change rate of the front surface resistance is more sensitive to the lightning damage than are those of the back surface resistance and the oblique resistance. Different simulated lightning currents have approximately the same action integrals at the inflection points of resistance change rate. The characteristics indicate that resistance change detection could be a possible method for the online monitoring of CFRP lightning damage.
