Abstract

Abstract: In order to study the bonding properties of different structural adhesives on carbon fiber composite substrates, seven different structural adhesives composed of epoxy resin, acrylate and polyurethane were used to bond carbon fiber composite-carbon fiber composite (CF-CF), and the tensile and shear strength were tested at room temperature and ultimate temperatures (80 ℃, -65 ℃). In order to explore the mechanical properties and failure modes of each adhesive, and test the bonding properties of epoxy structural adhesive to different fiber types of composites (T700-12K carbon fiber composite, T300-3K carbon fiber composite and glass fiber composite) at room temperature. The bonding mechanisms of carbon fiber and glass fiber composite are explored and then the adhesive with the best performance is obtained. It provides a reference for the selection of bonding agent between carbon fiber substrates in the fields of aerospace and automobile.

Key words: carbon fiber reinforced composites, structural adhesive, single lap bonding, tensile shear strength
