Effect of a New Coupling Agent on Mechanical Properties of Domestic High-Modulus Carbon Fiber/Cyanate Composites

Abstract:

To improve the overall performance of the domestic high-modulus carbon fiber/cyanate composites, a macromolecular coupling agent (SCC) based on the raw material styrene, methyl acrylate and γ-methyl (acryloyl) trimethoxysilane was synthesized. It also studies the effect of coupling agent content on the mechanical properties of composites. The results show that the dosage of macromolecular coupling agent with 3%, the performance of the composite materials has been notable improved, its bend strength and interlaminar shear strength are 1100Mpa and 63.5Mpa, which has been raised 6.0% and 16.1%, respectively. SEM micrographs show that the addition of a coupling agent effectively improve the interface compatibility between the resin and fibers in composite.
