    • In human habitations suitable for mass production, there is a need for a flexible foldable film or sheet material having a combination of extreme light resistance, fatigue resistance, and heat reflection. I have found that a superior combination, and the only one for which an accelerated test indicates permanence over a period exceeding 40 years, comprises the following elements: a flexible foldable film assembly, the outermost layer of which consists of opaque flakes, preferably of metal, arranged substantially with the flat side parallel to the surface, and held in a matrix of a resin belonging in the groups of acrylates and methacrylates, superimposed upon a black thermoplastic film containing at least 4 percent of a finely dispersed carbon black, this film being followed by a central layer having a modulus at least 50 percent lower than its adjacent layers, so that it will permit flexing while minimizing the stresses in such flexing. This low modulus layer further contains continuous fibers arranged in layers so that the fibers in each layer are substantially parallel with each other; and further, another second outside layer, on the other side of the central layer, at least one of the outer layers having stiffness and resistance higher than those of the said low modulus central layer, and preferably similar to that of the first outside layer on the opposite side of the said low modulus layer.
    • 在适于批量生产的人类习惯中,需要具有极耐光性,耐疲劳性和热反射组合的柔性折叠薄膜或片材。 我发现一个优越的组合,只有一个加速测试表明超过40年的持久性,包括以下要素:柔性可折叠膜组件,其最外层由不透明薄片,优选金属制成 基本上平坦地布置,并且保持在属于丙烯酸酯和甲基丙烯酸酯基团的树脂的基体中,叠加在含有至少4%的细分散的炭黑的黑色热塑性膜上,该膜是 随后是具有比其相邻层低至少50%的模量的中心层,使得其将允许弯曲同时最小化这种弯曲中的应力。 该低模量层还包含布置成层的连续纤维,使得每层中的纤维彼此基本平行; 并且还有另一个第二外层,在所述中心层的另一侧上,所述外层中的至少一个具有比所述低模量中心层的刚度和电阻高的刚度和电阻,并且优选地类似于第一外层的外层 所述低模量层的相反侧。
