碳纤维强度的统计特性及对复合材料线芯力学性能的影响
Study of statistical characteristics of carbon fiber and effects on mechanical properties of carbon fiber composite cores
摘要
Abstract
Single fiber and fiber bundle tensile strengths of Chinese-made carbon fiber were tested and its average single fiber tensile strength was described by the Weibull statistical method.The carbon fiber reinforced composite core was made by pultrusion process with the Chinese-made carbon fiber.The bending and shearing properties of the composite core were studied.Results show that,compared with the Toray T300 carbon fiber from Japan,domestic carbon fiber has almost the same average single fiber tensile strength,lower discrete property and a little lower average fiber bundle tensile strength.The aggregation property of the domestic carbon fiber is not good enough.Carbon fiber yarns were nipped and fluffed when being drawn out.No significant difference can be found from the mechanical properties of the composite cores made with the domestic carbon fiber and the Toray T700 carbon fiber from Japan.关键词
