Abstract Laminate composite materials have excellent coefficient of stiffness to weight and because of this laminates are very widely applied often replacing raditional materials. A very interesting group of such a type materials are the hybrid ones. A main disadvantage of hybrid composite materials is the weak impact strength. The paper presents results of testing handmade screw joint hybrid composite materials. Results of testing are compared with numerical analysis based on the Finite Elements Method. Investigations were made on designed for this purpose the statical stresses laboratory stand. The testing specimens were made by a contact method (handmade laminating) and laminar mats or woven fabrics spreading (resin supersaturated). (© 2011 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
