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

摘要：

　　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 ll00Mpa 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.
