    • A method of forming a pultruded shaped composite material comprising carbon fiber having a diameter not greater than 0.001 inch aligned linearly with a degree of waviness defined by an average amplitude to length (A/L) ratio of less than 0.9 percent in a matrix is formed around the fiber and solidified or cured into a rigid form that will not melt during subsequent processing steps to prevent an increase in waviness during subsequent processing steps. The compressive strength of the composite material approaches the tensile strength of the material. The matrix material consists essentially of a resin present in the range of about 10 to 50 percent by volume of the composite material. The A/L ratio is determined by measuring the distribution of angularity found in the aligned carbon fibers in a selective cross section cut at five degrees to the fiber plane, wherein the standard deviation for a 300 sample angularity measurement is not greater than 0.88 degrees.
    • 形成拉伸成形复合材料的方法,其形成直径不大于0.001英寸的碳纤维,其直径与在矩阵中的平均幅度对长度(A / L)比率小于0.9%所定义的波纹度线性排列, 围绕纤维固化或固化成刚性形式,其在随后的加工步骤期间将不会熔化,以防止随后的加工步骤中波纹的增加。 复合材料的抗压强度接近材料的拉伸强度。 基质材料基本上由复合材料的约10至50体积%范围内的树脂组成。 A / L比通过在与纤维平面成五度切割的选择性横截面中测量在对准的碳纤维中发现的角度分布来确定,其中300个样品角度测量的标准偏差不大于0.88度。
