Abstract

Adhesion strength τ of joints of a fiber–epoxy matrix was studied upon multiple repetition of the curing process. It has been shown that recuring weakens the interface. After a 12-fold cure, the values of τ are reduced by 30%. The possible causes of the observed changes are considered. The fall of τ should be considered when designing products made of GFRP.
