The article presents the results of research on selected mechanical properties of glass-epoxy laminates in terms of the matrix used. The quantitative and qualitative influence of epoxy resin cross-linked with different hardeners, and in different proportions, on the specific strength Rm/γ [kPa · m3/N] and specific stiffness E/γ [kPa · m3/N] of the composites (where γ is the specific weight) is described. Strength properties were calculated based on measurements from a static tensile test. Epidian 601 epoxy resin cross-linked with IDA and PAC hardeners was used to make the samples. The reinforcement was a glass fabric with a basis weight of 1008 g/m.The most commonly used composite materials include composites based on epoxy resins. Epoxy resins are synthetic materials obtained as a result of the polycondensation of epichlorohydrin or glycerol dichlorohydrin with dihydric phenols. They occur as viscous liquids or brittle solids, which only transform into insoluble and infusible materials during the curing process. (…)
