Paragraph starter

The integration of soft, compliant backing layers onto stiff fibre-reinforced adhesives has been shown to significantly enhance conformability and friction on curved substrates. This biomimetic approach, inspired by natural adhesive systems, allows for increased contact area by enabling the adhesive to better match surface topography. Therefore, when designing adhesive solutions for variable or non-ideal surfaces, incorporating materials with controlled compressibility in the backing layer is a key strategy for improving performance.
