Role of Viscosity on Optimum Polymer-Fibre Interaction during Rotational Moulding Sintering

The present work investigated the effect of polymer viscosity properties on sintering a fibre-reinforced rotationally moulded composite part. Previous researchers have concluded that characterisation is fundamental to achieving optimum materials processing in rotational moulding. Nevertheless, presence disperse phase during directly impacts current understanding how works heating. Lack pressurisation moulding implies an absence driving forces strongly bond two together as necessary structures. It means and densification are phases which or more can create interface transmit stresses. A novel single-particle interaction test (FPIT) adhesion sintering. was developed identify parameters achieve best fibre. focused measuring polymers' angle contact (AoC) fibre better understand coverage. Combinations glass (G.F.) with polyethylene (P.E.) various melt flow indexes (MFI) were tested role fibre-polymer adhesion. Attempts automate measurement proved challenging, so manual be effective. Sintering results showed has critical wetting, use Hi-MFI resins plasticisers improve Finally, polymer-fibre plays crucial densification, ongoing conclusions about affect full-scale manufacturing process.
