Fibre Reinforced Composites

This study investigated the effect of intumescent mats (M1 and M2) with different compositions on the post-fire performance of carbon fibre reinforced composites. The sandwich structure was designed for composites where M1 (carbon fibre reinforced composite-M1) or M2 (carbon fibre reinforced composite-M2) mats were covered on the composite surface. A significant reduction in the peak heat release rate and total heat release was observed from the cone calorimetric data, and carbon fibre reinforced composite-M1 showed the lowest value of 148 kW/m2 and 29 MJ/m2 for peak heat release rate and total heat release, respectively. In addition, a minor influence on mechanical properties was observed due to the variation of composite thickness and resin volume in the composite. The post-fire properties of composite were characterised, and the M1 mat presented better retention of flexural strength and modulus. The feasibility of two-layer model was confirmed to predict the post-fire performance of composites and reduce the reliance on the large amounts of empirical data.

Fibre Reinforced Composites

Composite materials combine the advantages of their components. Carbon fibre reinforced composites are used in construction where reduced weight is critical. To produce carbon fibre reinforced composites, aluminium alloys can be the matrix. Advantageous properties of aluminium matrix composites – good toughness, low weight – are applied in aerospace and automotive industry. Because aluminium alloys are not reactive to carbon, therefore the coating of the fibres can solve the problem. Nickel coated and chemically treated carbon fibres were used to producing of aluminium matrix composites. The investigated composite materials were prepared by pressure infiltration. The influence of treating of carbon fibres was examined on the fracture mechanical properties of aluminium matrix composites. Three types of matrix materials, three types of carbon fibres and four types of surface treatment were studied. Fatigue crack growth tests were performed under mode I loading condition and the failure mechanisms of the composite materials were investigated. Test results belonging to different coated fibres were compared, and our results were compared with the results from the literature, too.
