Interface and its effect on the interlaminate shear strength of novel glass fiber/hyperbranched polysiloxane modified maleimide-triazine resin composites

► Hydroxyl groups on surfaces of glass fibers react with Si-OH groups of hyperbranched polysiloxane, forming chemical and hydrogen bonds. ► The chemical and hydrogen bonds provide improved interfacial adhesion between hyperbranched polysiloxane modified maleimide-triazine (mBT) resin and glass fibers. ► Original maleimide-triazine resin does not have good interfacial adhesion with glass fibers. ► Better interfacial adhesion guarantees a desirable property-transition from the matrix to the resultant composites. ► Novel advanced glass woven fabric/mBT resin composites with higher interlaminate shear strengths are developed.
