The wide range of applications of microwave technology in manufacturing industries has been well documented (NRC, 1994; Thuery, 1992). In this paper, a new way of joining fibre reinforced thermoplastic composites with or without primers is presented. The microwave facility used is also discussed. The effect of power input and cycle time on the heat affected zone (HAZ) is detailed together with ...

Fatigue strength of injection moulded short fibre reinforced polymer components depends upon fibre orientation with reference to the acting stresses. For the case of a short glass fibre reinforced (SGFR) polyamide 6, this dependence was expressed through a relationship derived from the Tsai-Hill criterion [1], with the strong assumption that fibres were parallel to each other. This relationship...

This article features a large statistical database on the tensile properties of natural fibre reinforced composite laminates. The data presented here corresponds to a comprehensive experimental testing program of several composite systems including: different material constituents (epoxy and vinyl ester resins; flax, jute and carbon fibres), different fibre configurations (short-fibre mats, uni...

The aim of this investigation was to measure the flexural and compressive strengths and the corresponding moduli of cylindrical composite specimens reinforced with woven glass fiber. Test specimens were made by light-curing urethane dimethacrylate oligomer with woven glass fiber of 0.18-mm standard thickness. Tests were conducted using four reinforcement methods and two specimen diameters. Flex...

objective(s): the aim of this study was to synthesis new dental nanocomposites reinforced with fabricated glass nanoparticles and compare two methods for fabrication and investigate the effect of this filler on mechanical properties. materials and methods: the glass nanoparticles were produced by wet milling process. the particle size and shape was achieved using psa and sem. glass nanoparticle...

Holmes and Shuler [1] recently found that significant internal heating occurs during the cyclic loading of fibre-reinforced ceramics. In their investigation, conducted with cross-ply carbon fibre/SiC matrix composites (hereafter referred to as Cf/SiC), it was observed that the extent of internal heating was strongly influenced by the peak fatigue stress and loading frequency. For example, durin...

The production process of fibre reinforced autoclaved aerated concrete results in a preferential orientation of the fibres. The fibre orientation largely influences the strength and the deformation behaviour of this building material, therefore information on the fibre orientation is highly desirable. Computed tomography measurements allow for the non destructive investigation of the material. ...
