Manufacturing carbon-fibre reinforced polymer (CFRP) composites via different techniques often leads to contrasting surface topographies. Such differences can affect any subsequent pre-treatments that are performed and these ultimately joint strength. In the present work, CFRP adherends made using compression moulding or autoclaving were investigated. Pre-treatment of acetone cleaning, plasma t...

The studies on wollastonite reinforced recycled ABS (Acrylonitrile butadiene styrene) composites were investigated. Powder-based with a particle size of 13 microns was mixed Acrylonitrile styrene in various proportions wt.%. Recycled homogeneously and composite prepared using twin-screw extruder it pelletized. specimens the injection moulding process mechanical properties like tensile strength ...

Figure 2 Technique of splinting metacarpal fractures directly or using the proximal phalanx as a piston. The main issue with the closed technique is maintaining the reduced position in a plaster cast once moulding is complete, thereby commonly necessitating surgical stabilisation. We describe a novel and useful technique that maintains the reduction in the intrinsic plus (Edinburgh) position wi...

[Most of the ideas in this paper evolved during work on design studies for the EEC Machine Transla t ion Project Eurotra. We are grateful to the Commission of the European Communit ies for permission to publish these ideas, and to our Eurot ra colleagues particularly Maghi King, Dieter Maas, Bente Maegaard, and Serge Perschke for many useful contributions, which have been influential in mouldin...

The recent innovations in dry etching make it a promising technology for the fabrications of micromoulds. The high aspect ratios, directional freedom, low roughness, high etch rates and high selectivity with respect to the mask material allow a versatile fabrication process of micromoulds for subsequent electroplating and embossing, as is demonstrated with the DEEMO process. DEEMO is an English...

Highly filled polymeric suspensions, such as those involved in Powder Injection Moulding (PIM), exhibit complex rheological behaviour. A detailed understanding of the rheology of these suspensions is prerequisite for their optimum and safe processing. In present paper, rheological behaviour of highly filled WC-Co compounds during capillary flow was studied with emphasis on apparent slip. Contri...

Original scientific paper Heat treatment of active components of cold – moulding tools is a necessary operation to guarantee their functionality. The tools made by this method loose the required quality of durability and period of service and losses caused by their frequent exchange are high. One way we can stop it is by coating the active parts of pressing tools by thin, hard and abrasion resi...

Climate change, environmental degradation, loss of biodiversity, changes in the ecosystem and disasters play an important role development economic advancement. In Zororo Village, Zimbabwe, biodiversity have occurred rapidly during last few decades. A literature review, key informant interviews, focus group discussions were methodologies used for this research. All participants agreed that had ...

Flow conditions during compression moulding of Sheet Moulding Compounds (SMCs) govern the microstructure and resulting mechanical properties composite parts. Low-density high-fibre content SMCs were subjected to simple compression, œdometric through-thickness shear loadings, using dedicated rheometers. Simple experiments revealed compaction behaviour both types SMCs. During experiments, low-den...
