A composite material can be defined as the combination of two or more materials with the aim of obtaining a new product with improved properties. Composite materials, composed of a polymer matrix reinforced with fibers, are currently used as structural elements, in spite of the uncertainties on strength, deformability and durability. The use of pultruded profiles in shapes similar to those used in metallic construction, results in an interesting solution for this material when high resistance. protection against chemical attacks and lightness are required.
The structural key point of those materials are the joints. The present paper is focused on joints composed of bolted plates on the wings of IPN pultruded profiles. Different tests conducted in LABEIN are described. Likewise, this paper deals with tests carried out with the purpose of analysing the feasibility of joints with high resistance bolts.
