摘要： Uncured thermosetting resins are loaded with relatively high amounts of solid thermoplastic resin particles to form a resin precursor. The resin precursor is heat treated so as to produce an uncured resin composition wherein the thermoplastic resin particles become substantially dissolved in the thermosetting resin without causing cure of the resin mixture. Heat treatment of highly loaded thermosetting resins in accordance with the present invention provides uncured resin compositions that are well suited for use in fabricating composite structures and particularly prepreg for use in lightning protection surface coatings.

摘要： A core crush resistant prepreg for use in making a fiber reinforced composite panel structure is provided. The prepreg comprises a woven fabric consisting essentially of carbon fiber tow strands impregnated with a hardenable polymeric resin composition. Typically the fabric has an areal weight of from about 180 to about 205 grams per square meter. The prepreg has an average fiber tow aspect ratio of less than about 15.4, a prepreg thickness of at least about 0.245 mm, and a prepreg openness of at least about 1.2 percent but less than about 6.0 percent. Preferably, the resin composition is predominantly viscous in nature and has a tan &dgr; value of between 0.9 and 2.0 at an elevated temperature between 70° C. and 140° C., and an average epoxy functionality of greater than 2.0. A method for evaluating core crush resistance properties of a prepreg is also provided. The method includes determining a fiber tow average aspect ratio of the prepreg, determining a prepreg thickness, and comparing said average fiber tow aspect ratio and prepreg thickness to a set of predetermined values.
摘要翻译： 提供了一种用于制造纤维增强复合板结构的芯抗压预浸料。 预浸料包括基本上由浸渍有可硬化聚合物树脂组合物的碳纤维丝束组成的机织织物。 通常，织物的面积重量为约180至约205克/平方米。 预浸料坯的平均纤维束纵横比小于约15.4，预浸料坯厚度至少约0.245mm，预浸料坯开度至少约为1.2％但小于约6.0％。 优选地，树脂组合物在本质上主要是粘性的，并且在70℃和140℃之间的升高的温度下具有在0.9和2.0之间的tanδ值，并且平均环氧官能度大于2.0。 还提供了一种用于评估预浸料坯的耐芯击抗性的方法。 该方法包括确定预浸料坯的纤维束平均纵横比，确定预浸料坯厚度，以及将所述平均纤维束纵横比和预浸料坯厚度与一组预定值进行比较。
