Curable thermosetting resin compositions comprising at least one cycloaliphatic epoxy resin having at least two 1,2-epoxy groups per molecule, and certain aromatic diamines having three aromatic rings in the molecule are disclosed. Resin compositions comprised of, for example, bis(2,3-epoxycyclopentyl)ether and 1,3-bis(4-aminophenoxy)benzene exhibit a highly desirable balance of physical and chemical properties which renders such compositions ideally suited for use in the fabrication of wet winding composites. The resin compositions prepared in accordance with the invention have unexpectedly low viscosity, high glass transition temperatures, high tensile properties and unexpectedly low water uptake. Accordingly, the resin compositions find particular application in the preparation of composites by wet winding procedures.
本发明公开了可固化热固性树脂组合物,该组合物包含至少一种环脂族环氧树脂,其分子中至少有两个 1,2-环氧基团,以及某些芳香族二胺,其分子中有三个芳香环。 由双(2,3-环氧环戊基)醚和 1,3-双(4-氨基苯氧基)苯等组成的树脂组合物显示出非常理想的物理和化学性质平衡,使这种组合物非常适合用于制造湿法缠绕复合材料。 根据本发明制备的树脂组合物具有出乎意料的低粘度、高玻璃化转变温度、高拉伸性能和出乎意料的低吸水性。 因此,这种树脂组合物特别适用于通过湿法缠绕程序制备复合材料。
