Demanufacturing of thermoplastic composites: Small scale experiments exploring ply separation and recovery (2024)
Journal Article
Parsons, A. J., Johnson, M. S., Piano, S., & De Focatiis, D. S. (2025). Demanufacturing of thermoplastic composites: Small scale experiments exploring ply separation and recovery. Composites Part A: Applied Science and Manufacturing, 190, Article 108626. https://doi.org/10.1016/j.compositesa.2024.108626

Thermoplastic composites are intrinsically suited to recycling, but processes are poorly realised. Methods applied to thermosets are energy intensive, resulting in fibre downgrading and matrix loss. With digital manufacturing and data intertwining, t... Read More about Demanufacturing of thermoplastic composites: Small scale experiments exploring ply separation and recovery.

Ramli, R., Chai, A. B., Kamaruddin, S., Ho, J. H., Mohd. Rasdi, F. R., De Focatiis, D. S. A., Ong, S. K., & Bachmann, R. T. (2024). Effects of oil palm trunk biochar as filler on physical and mechanical properties of deproteinised and epoxidised natural rubber latex foam. Journal of Rubber Research, 27, 623-637. https://doi.org/10.1007/s42464-024-00283-1

Oil palm trunk biochar (OPTB) serves as a flame-retardant additive aimed at enhancing the thermal stability of natural rubber (NR) latex foam. This study explores whether OPTB affects the physical and mechanical properties of specialty NR (SpNR) late...
