Development and characterisation of injection moulded, all-polypropylene composites [PDF]

eXPRESS Polymer Letters, 2013
In this work, all-polypropylene composites (all-PP composites) were manufactured by injection moulding. Prior to injection moulding, pre-impregnated pellets were prepared by a three-step process (filament winding, compression moulding and pelletizing). A

Compression moulding and injection over moulding of porous PEEK components [PDF]

Journal of the Mechanical Behavior of Biomedical Materials, 2020
A simple and adaptable process for the production of porous PEEK has been demonstrated herein, which uses compression moulding to infiltrate molten PEEK into of a packed bed of salt beads. The process has the capacity to vary the pore size and porosity within the range suitable for materials to replace bone, but compressive testing showed the stiffness

Experimental investigation and optimization of compression moulding parameters for MWCNT/glass/kevlar/epoxy composites on mechanical and tribological properties

Journal of Materials Research and Technology, 2021
The mechanical properties of hybrid composites are largely influenced by the reinforcing fibres, nanofillers, matrix materials and fabrication methods. Multi-wall carbon nanotubes (MWCNTs) fillers reinforced to E-glass/Kevlar/epoxy composites (GKEC) are ...

Modeling and 3D Simulation of the Mould Compression and Resin Flow for Force-Controlled Compression Resin Transfer Moulding

Medžiagotyra, 2019
Since the existence of the complicated coupling between mould compression and resin flow, the full 3D simulation of the filling process in force-controlled compression resin transfer moulding (CRTM) has not been realized, especially when the resin flow ...

Experimental flow-front visualisation in compression moulding of SMC

Composites Part A: Applied Science and Manufacturing, 2004
This work is primarily focused on experimental visualisation of the flow during mould closure in compression moulding of sheet moulding compound. Circular plates are manufactured with industry scale equipment at close to production conditions. Special attention is given to the advancing flow front, for which the full complexity is captured by means of ...

Functionalised biochar in biocomposites: The effect of fire retardants, bioplastics and processing methods

Composites Part C: Open Access, 2023
Fire retardants, although can impart fire-safety in polymeric composites, are detrimental to the mechanical properties. Biochar can be used, in conjunction with fire retardants, to create a balance between fire-safety and mechanical performance.
