Fibre reinforced plastic (FRP) composites prepared from E glass woven fabrics as reinforcing agent and carboxyl terminated poly(ethylene glycol) adipate (CTPEGA) modified epoxy as a matrix, were subjected to dynamic mechanical thermal analysis at a fixed frequency of 5 Hz. The volume fraction of glass was about 0.45. The concentration of CTPEGA in the matrix was varied gradually from 0 to 40 phr (phr stands for parts per hundred parts of resin), to investigate the effect of CTPEGA concentration on the dynamic properties of the composites. It was found that the tan δ peak temperature and storage modulus gradually decrease with incorporation of CTPEGA. However, the tan δ peak value increases up to 20 phr of CTPEGA concentration and decreases thereafter. The same trend was obtained in the case of impact strength. © 2000 Society of Chemical Industry
