通过嵌入基质中的刚性颗粒增强纤维复合材料，可以实现简单、经济的功能分级，增强对机械载荷的响应，并改善高温下的功能。这里，我们考虑由这种材料制成的层合板，其中球面钢筋按层定制。这种材料的模数处于相对较窄的范围内。我们考虑了两种不同的模数估计：一种是将纤维嵌入到一个均匀的颗粒基质中的“两步法”，另一种是我们使用Benveniste(1988)方法以一种简单的方式重新推导的方法。探讨了板材的优化剪裁，并证明了功能分级可以改善所考虑的结构的性能。以承受均匀横向压力的正方形、简支式、交叉式层合板为例，适度的功能分级可显著提高性能。第二个例子表明，仅以重量的小幅增加为代价，面板就获得了卓越的抗爆性。
Reinforcement of fibrous composites by stiff particles embedded in the matrix offers the potential for simple, economical functional grading, enhanced response to mechanical loads, and improved functioning at high temperatures. Here, we consider laminated plates made of such a material, with spherical reinforcement tailored by layer. The moduli for this material lie within relatively narrow bounds. Two separate moduli estimates are considered: a “two-step” approach in which fibers are embedded in a homogenized particulate matrix, and the approach, which we re-derive in a simple way using the Benveniste (1988) method. Optimal tailoring of a plate is explored, and functional grading is shown to improve the performance of the structures considered. In the example of a square, simply supported, cross-ply laminated panel subjected to uniform transverse pressure, a modest functional grading offers significant improvement in performance. A second example suggests superior blast resistance of the panel achieved at the expense of only a small increase in weight.
