Structural batteries are multifunctional devices that store energy and carry mechanical load, simultaneously. The pivotal constituent is the carbon fibre, which acts as not only structural reinforcement, but also electrode by reversibly hosting Li ions. Still, little known about how fibres interact. Here we map inserted in polyacrylonitrile based with Auger electron spectroscopy (AES). We show ...

Many of the carbon and natural fibres used in composite reinforcement have a non-circular cross section. Recently non-circular, or flat, section glass fibre products become commercially available. This paper explores potential effects that such shapes may on micromechanics stress transfer at fibre–matrix interface resulting changes strength performance. Analytical modelling is to show how criti...
