Composites Part A: Applied Science and Manufacturing, 2017
Abstract The properties of Sheet Moulding Compounds (SMCs) are altered by their porosity induced during the manufacturing or moulding of these prepregs. To characterise the pore scale mechanisms occurring during SMC flow, 3D synchrotron X-ray images were acquired during the compression of two uncured SMCs. For the high fibre content SMC ( 50 wt

Journal of Reinforced Plastics and Composites, 2015
Partly presented in Interdisciplinary Transport Phenomena VII, Dresden, Germany, 19–23 September 2011. Compression moulding experiments of sheet moulding compound, visual observations of a vacuum test with prepregs and numerical models with two main approaches for computational fluid dynamics simulations of the mould filling phase are presented.

Compression Moulding of Thermoplastic Nanocomposites Filled with MWCNT [PDF]
Polymers and Polymer Composites, 2017 Multi-walled carbon-nanotubes (MWCNTs) were melt-mixed with three different thermoplastic matrices (polypropylene, PP, polycarbonate, PC, and thermoplastic polyurethane, TPU) to produce nanocomposites with three different filler contents (1, 3, and 5 wt.%).

Process monitoring of moulding compounds by ultrasonic measurements in a compression mould
NDT & E International, 2000Current research addresses ultrasonic quality sensor utilisation for inline cure monitoring, to control and analyse compression moulding. In this investigation, an ultrasonic impulse transmission method was applied to directly monitor changes in the mechanical properties of moulding compounds throughout the whole cure cycle.

A Comparison of Sandwich Injection Moulding and Sandwich Injection-Compression Moulding
Journal of Polymer Engineering, 2006Multi-component injection moulding has gained enormous importance over the last fifteen years. This is due to development of more sophisticated products and to the constant endeavours to cut costs. One new trend - the combination and integration of well-known processes to a new process - has become more and more important for some years and it still ...

Compression Moulding of Polypropylene Foams and Their Properties
Cellular Polymers, 2008Compression moulding was used to produce polypropylene foams using azodicarbonamide as a chemical blowing agent. The morphology of the foams is reported in terms of cell size, cell density, and skin thickness using 1.5, 2, 2.5 and 3% of blowing agent.

Composites Part A: Applied Science and Manufacturing, 2012
Compression moulded preimpregnated polymer-matrix composites are often porous materials. Rheological studies usually neglect their subsequent compressible complex flow behaviour, together with mouldcomposite friction effects. Therefore the proposed method, including a newly developed compression rheometer, allows the rheology and the compressibility of

Autoclave, Compression Moulding
1985Autoclave and compression moulding are wellknown technologies in use for the fabrication of fibre composite structures. Aside of the general knowledge a lot of details has to be taken care of to ensure troublefree application.
