N2 - Biobased fibre reinforcements (hemp, jute, flax) derived from agricultural waste and forestry are increasing its potential towards advanced composites promoting environmental benefits and thermal recycling (including a reduction in CO2 emissions and the fossil fuel depletion). Currently, there is a growing interest of natural fibres due to its lower density, and higher modulus-to-densityratios compared to glass and carbon fibre reinforcements. The present work was intended to understand how the flax fibre layups and oreintation affect the behavior of laminated composites in bending. Unidirectional [0]2S, cross-ply [0/90]S, and angle-ply [+45/-45]S laminates made up of flax fibre reinforced epoxy composites are considered to study flexural stresses and mid-spandeflections. Basic principles of the classical beam theory (CBT) are applied for obtaining analytical solutions, which were also compared with the finite element simulation results.
