Fiber/Matrix Adhesion in Glass Fiber Reinforced Inorganic-Organic Polyurea/Polysilicate Resins

Abstract:

In this work newly developed phosphate-free polyurea/polysilicate resins (denoted as 2P) were explored and compared to market established 3P Resins® regarding their fiber/matrix adhesion with coupling agents introduced for further property improvement. Fiber/matrix adhesion was determined by macro mechanical test, i.e. interlaminar shear strength (ILSS), double-cantilever beam (DCB), Charpy impact, and tensile tests.It was demonstrated that 2P resins containing epoxidized linseed oil (ELO) replacing unfavorable organic phosphate esters in 3P Resins® as phase transfer agents nearly reach similar adhesion properties between fiber and matrix compared to established 3P Resins®. Additionally, some coupling agents were found to increase the ILSS by up to 26 %, the energy release rate by up to 7 %, the Charpy impact strength by up to 18 %, and the tensile modulus by up to 11 %.
