This is a book about what can be achieved when tried and tested fibres are combined with other materials - often (bio) plastics - to create fibre reinforced composite materials. These fibres can be manifold: carbon, glass, a synthetic fibre or natural fibres such as flax, hemp, jute, ramie, silk... The strength and stiffness of these fibres, combined with the lightness of plastics, inspires designers to create lightweight, energy-efficient products. At the same time, the composite materials allow a great freedom of shape and design. Designing and using composite materials can be an answer to the social and ecological challenges today's society is facing. This book, edited by Lut Pil and Ignaas Verpoest, focuses on the results achieved in the past five years and looks ahead to some of the breakthroughs that are expected in the years to come. The projects presented in the book are diverse and come from different sectors such as mobility, sports, medical applications, energy supply, infrastructure, architecture and products for daily use. Exhibition: Design Museum Gent, Belgium (26.10.2018-21.04.2019).

The mechanical behavior of hybrid glass and steel fiber composites is investigated by interlayer hybridization. The goal is to isolate different effects on the possible hybrid effect and analyze the differences. The three effects that are analysed, are the influence of the matrix ductility, the ratio of steel/glass fibers and the stacking order. The effect of the matrix will mainly be influenced by difference in delamination strength. A low delamination strength will result in high delamination length with a high total strain as a result. If the delamination length is limited, the strain will be localised in the delaminated zone and failure will occur at lower measured strains. This behavior is succesfully modeled when the delamination will preferably take place at the steel/glass interface.Because of the difference in thermal expansion coefficient between glass and steel, compressive stresses will be present after production on the glass fibers. This will postpone the failure of glass fibers. This effect is enhanced if the glass layers are mixed between the steel layers and if the steel/glass ratio is increased. Of course also the production temperature will have a large influence. Multiple fractures of the glass fibers are observed in the hybrids with a high steel/glass ratio, regardless of the stacking order. As a result the stress will remain higher compared with the rule of mixture. This is a positive hybrid effect. The stacking order will have a large influence on the length of the delaminations. A lot of steel/glass interfaces will result in a smaller delamination length. Also the damage to the steel fibers due to the fracture of the glass fibers will be higher if the glass fibers are mixed more between the steel fibers. Smaller delamination length and more damage will result in a smaller total strain.
