This hybrid solution provides a 40% weight reduction by replacing the steel crossbeam with a composite variant. This composite variant is produced using overbraiding to apply dry fibres over a preshaped core after which the fibres are impregnated using resin transfer moulding. The steel interfaces needed to be redesigned into a surface-to-surface connection to maintain fibre integrity.

ThermopiercingThermoforming Fibre Displacement

Redesign of an arm-rest for a pediatric wheelchair using semi-manufactured com-posite carbon panels and thermoforming to reduce product weight and production time. A unique weave was chosen to make it aesthetically more appealing while providing flexibility for reinforcing the mounting gaps when piercing the holes with heated pens.

Absorbing Honeycomb BaseFunctional base concept of a large polymer container for the transportation of hazardous or valuable liquids. A honeycomb medium was chosen for its strength in the vertical direction. It can maintain integrity when stacked and partially absorb impact when dropped at an angle.

Expanse, office storageExpanse is a low profile office product, based on injection moulding, designed as an addi-tion to a work space. The product can slide on to most table surfaces to provide additio-nal storage. The long Expanse functions as a document holder while the smaller Expanse can be used to store books, office supplies and accessories.

Surface ModelingA rendered concept of a miniature toy submarine for injection moulding. Based of an existing concept it consists of 3 parts: the two external hull pieces and internal shell for details.
