1 前言由上海航天局八一○所提供碳纤维复合材料,作单向板和正交板的拉、压、弯、剪试验,16组,共83根试样。碳纤维管子作拉伸、弯曲、扭转、弯剪、胶接拉脱等试验,共26根试样。增强材料为碳纤维M40B—3000,相对密度1.84,拉伸强度1800MPa,弹性模量397GPa;基体为环氧648,相对密度1.25,弹性模量2.5GPa,以下对测试结果进行分析。2 平板性能分析为了进行性能分析,必须要了解复合材料的铺层及树脂含量。对于碳纤维复合材料,比较实用的,可以从测定材料密度,从而 1 Preface The carbon fiber composite material provided by Shanghai Aerospace Bureau, Bailao, was used for drawing, pressing, bending and shearing tests of one-way and quadrature plates. There were 16 groups of 83 samples. Carbon fiber tubes for tensile, bending, torsion, bending shear, adhesive pull off and other tests, a total of 26 samples. The reinforcing material is carbon fiber M40B-3000, the relative density is 1.84, the tensile strength is 1800MPa and the elastic modulus is 397GPa. The matrix is ​​epoxy 648, the relative density is 1.25 and the elastic modulus is 2.5GPa. The test results are analyzed below. 2 flat panel performance analysis For performance analysis, we must understand the composite materials and resin layer. For carbon fiber composites, more practical, from the determination of material density, thus
