LONG-TERM CREEP OF HYBRID ARAMID/GLASS-FIBER-REINFORCED PLASTICS

摘要

The results of experimental investigation of the long-term creep of SVM aramid fibers, EDT-10 epoxy resin, aramid-epoxy FRP (fiber-reinforced plastics), glass/epoxy FRP, and aramid/glass-epoxy hybrid FRP with different volume fractions of aramid and glass fibers are presented. The long-term tests were continued for 50000 h (5.7 years) A structural approach for predicting the long-term creep from the properties of components is considered. The effect of hybridization on the inelastic deformation of hybrid FRP is discussed. The redistribution of stresses in the components during the long-term creep of hybrid composites is analyzed.
