Fused deposition modelling (FDM) is one of the most popular additive manufacturing (AM) technique which used to investigate elastic properties 3D printed polyamide-based polymer composites structures. The aim this work study mechanical continuous carbon fibre reinforced polyamide composite samples using tensile and flexural testing by varying volume contents with applying pressure, temperature ...

A novel method based on selective laser sintering (SLS) process is proposed for the first time to prepare complex and high-performance carbon fibres/polyamide12/epoxy (CF/PA12/EP) ternary composites. The procedures are briefly described as follows: prepare polyamide12 (PA12) coated carbon fibre (CF) composite powder; build porous green parts by SLS; infiltrate the green parts with high-performa...

Fibre reinforced plastics are increasing their importance as one of the most interesting groups of material on account of their low weight, high strength and stiffness. To obtain good quality holes, it is important to identify the type of material, ply stacking sequence and fibre orientation. In this paper, the drilling of quasi-isotropic hybrid carbon+glass/epoxy plates is analyzed. Two commer...

This paper presents the results of an experimental study of the mechanical properties of FRP reinforcement bars, used as internal reinforcement in concrete structures, at elevated temperatures. Two types of FRP bars namely: carbon fibre reinforced polyester bars of 9.5mm diameter and glass fibre reinforced polyester bars of 9.5mm and 12.7 mm diameter were used in the study. For comparison, conv...

Fibre metal laminates, hybrid composite materials built up from interlaced layers of thin metals and fibre reinforced adhesives, are future-proof used in the production passenger aircraft, yachts, sailplanes, racing cars, sports equipment. The most commercially available fibre–metal laminates carbon aluminium aramid glass laminates. This review emphasises developing technologies for forming met...

Aesthetic requirement of severely mutilated primary anterior teeth in the case of early childhood caries has been a challenge to pediatric dentist. Among restorative treatment options, prefabricated crown and biological and resin composite restoration either by means of direct or indirect technique are mentioned in the literature. This paper presents the clinical sequence of rehabilitation of m...
