摘要
对四种高模玻纤分别进行了浸胶纱的拉伸性能、层合板的单层厚度及0°拉伸性能的研究,并对四种高模玻纤对工字梁刚度的影响进行了模型分析。四种高模玻纤具有相近的原纱拉伸模量,层合板在等纤维体积含量下具有相近的0°拉伸模量,但是在真空导入成型工艺中,由于单层厚度的差异导致纤维体积分数不同,从而具有不同的0°拉伸模量。在应用于同样铺层的工字梁时,单层厚度为0.78mm的高模玻纤层合板对应的工字梁刚度比单层厚度为0.83mm的高模玻纤层合板增加约6%。
Tensile properties of glass fiber yams, ply thickness and 0° tensile properties of the laminated plates for the four kinds of high modulus UD glass fabric are studied. They have close tensile modulus for the glass fiber yams, and close tensile modulus for the UD composites, when the fiber volume contents are controlled to be similar. However, by vacuum assisted infuse process, the UD composites have different ply thickness, and therefore different fiber volume contents, finally different tensile modulus. When applied in the I-beam with same layer, the stiffness for ply thickness of 0. 78 mm increases by about 6% compared with the stiffness for ply thickness of 0. 83 mm.
