The paper presents some experimental studies on a regular cross-ply laminate of the [(0/90)F] 4S configuration. Each layer is VE 11-M vinylester resin (the manufacturer: ,,Organika-Sarzvna" Chemical Plants, Sarzyna, Poland) reinforced with plam weave carbon fabric of parameters: Stvle 430, Carbon 6K, substance 300g/m2, warp/weft 400/400 tex, 3.7/3.7 yarn/cm (the manufacturer: C. Cramer GmbH & Co. KG Division ECC). The orthotropic laminate was produced by ROMA private enterprise In Grabowiec, Poland, using the vacuum molding method and the technological parameters developed by ROMA taking into account the VE 11-M material specijication. The PN-EN ISO 14129:1997 standard [1] and closely related standards [2-9] were taken into consideration in experimental studies on the static in-plane shear response by a tensile test of a [(plus or minus 45)F]nS laminate. A program of the experiments was focused on testing a rate of a testing machine crosshead and a number of static stress cycles. An influence of these factors on the in-plane shear modulus was investigated. Based on the conducted investigations, the modified experimental procedure has been proposed for determination of the correct value of the in-plane shear modulus and the in-plane shear strength.
