The relationship between wood-bamboo composite laminates’ structure and the mechanics properties was studied. Based on the composite laminate’s theories, eight kinds of structures of wood-bamboo composite laminates were designed. Eight kinds of laminates’ the maximal load (Pmax), modulus of elasticity (MOE), modulus of rupture (MOR) and maximal flexibility (?) were measured. The results showed that it could increase the composite laminates’ the maximal load (Pmax), modulus of elasticity (MOE), modulus of rupture (MOR). Based on the principal components method, specific strength in four mechanics criterions could be chosen as the composite laminates’ judged criterion.
