    • Reinforcing fiber materials such as rovings, webbings, and other fiber maials are impregnated with a resinous binder material in such a manner that gaseous inclusions are avoided whereby a surprising increase in the strength of the fiber compound material is achieved. For this purpose the liquid resinous binder material is applied substantially only to one side of the reinforcing material which is then moved through an absorbing zone in which the liquid resinous binder material penetrates the reinforcing material substantially completely as a result of a predetermined residence time and temperature in the absorbing zone. Gas inclusions are removed by adsorption and/or by expulsion. The gas adsorbing and expulsion zone is a chamber in which a plurality of guide rollers are arranged so as to cause the impregnated material to repeatedly reverse its moving direction, whereby the sequential and repeated penetration of the reinforcing material by the resinous material and the removal of gas inclusions are enhanced. Further, the precise weight ratio adjustment of resin to fiber material is enhanced by moving the impregnated material in a substantially vertical orientation through a fulling station. The vertical orientation facilitates the flow off of excess resin.
    • 加强纤维材料如粗纱,网带和其它纤维材料用树脂粘合剂材料浸渍,以避免气态夹杂物,从而实现纤维复合材料的强度令人惊讶的增加。 为此,液态树脂粘合剂材料基本上仅施加到增强材料的一侧,然后通过吸收区域移动,其中液态树脂粘合剂材料基本上完全渗透加固材料,这是由于预定的停留时间和温度 在吸收区。 通过吸附和/或通过排出除去气体夹杂物。 气体吸附和排出区是其中布置多个导辊以使浸渍材料反复地反转其移动方向的室,由此通过树脂材料的顺序和重复的增强材料的渗透以及去除 气体夹杂物增强。 此外,通过使浸渍的材料以大致垂直的方向移动通过充气站,来提高树脂与纤维材料的精确重量比调整。 垂直方向有助于流过多余的树脂。

    • Shear transfer elements can be formed by winding or weaving unidirectional fibers on a support structure. In a winding operation the support structure consists of two intersecting planes of winding mandrels with the planes arranged in angularly spaced relation. Each plane has two pair of mandrels with the mandrels in each pair located on the opposite sides of the line of intersection between the two planes. After the fibers are wound on the mandrels, each mandrel is axially disposed in the opposite direction relative to the other mandrel in the pair and also to the adjacent mandrel in the other pair in the same plane. Next, the fibers are pressed to form the shear transfer element. In a weaving operation, the support structure consists of a pair of pivotally interconnected frames. The fibers are woven onto holders on the sides of each frame extending parallel to the pivot axis of the frames. After placement of the fibers on the frames, the frames are pivoted apart and the fibers are pressed to form the shear transfer element.
    • 剪切转印元件可以通过在支撑结构上缠绕或编织单向纤维来形成。 在卷绕操作中,支撑结构由缠绕心轴的两个相交平面组成,其中平面以角度间隔的关系布置。 每个平面具有两对心轴,其中每对中的心轴位于两个平面之间的相交线的相对侧上。 在纤维缠绕在心轴上之后,每个心轴相对于该对中的另一个心轴在相反方向上轴向地设置,并且在同一平面中的另一对中相邻的心轴。 接下来,将纤维压制以形成剪切传递元件。 在编织操作中,支撑结构由一对枢转互连的框架组成。 纤维被编织到平行于框架的枢转轴线延伸的每个框架的侧面上的保持器上。 在将纤维放置在框架上之后,框架枢转分开,并且将纤维压制以形成剪切传递元件。
