EXPERIMENTAL STUDY ON COMPRESSION PROPERTIES OF PULTRUDED GFRP LAMINATES

Abstract

Abstract: To investigate the compressive mechanical properties and the failure mechanism of pultruded glass fiber reinforced polymer (GFRP) laminates, matrix resin and fiber mass fraction were regarded as variable parameters, and longitudinal and transverse compression tests were conducted on six kinds of GFRP laminates. Compressive mechanical properties and failure modes were compared and analyzed. The result shows that matrix cracking is the typical longitudinal compressive failure mode, while the typical transverse compressive failure modes are shear failure and matrix cracking. Specimens with epoxy matrix exceled those with vinyl matrix in compressive mechanical properties. Increasing longitudinal fiber mass fraction can improve the longitudinal compressive mechanical properties to a certain extent. But, the fiber with too high mass fraction will have adverse effect. Changing fiber mass fraction has little influence on the transverse compressive mechanical properties.
