Abstract

The paper presents the most important results regarding mechanical properties of three-phase chopped strand mat-Al2O3 particles-SYNOLITE 8388 P2 polyester resin laminates subjected to short time static cyclic tension-compression loadings. Distributions of 10 cycles’ tension-compression loadings at various test speeds and cycle limits have been determined on a Lloyd Instruments LS100Plus materials testing machine. Maximum hysteresis data as well as stiffness distributions of specimens that exhibit maximum hysteresis have been presented. Extended researches regarding the behavior of these laminates subjected to short time static cyclic loadings have been accomplished, quantified in determination of over forty-five mechanical properties. Hysteresis data determined as a difference between first and last cycle extension have been reported at 10 mm/min test speed with a decreasing tendency once test speed is increased..
