    Abstract: A composite mandrel includes a filament-wound composite tube, and composite material molded over the filament-wound composite tube. For example, the composite material includes chopped fibers and a matrix of thermoset resin. The chopped fibers are arranged in layers upon the filament-wound composite tube, and the chopped fibers in each of the layers are randomly oriented along first and second orthogonal directions in each of the layers. The composite material includes at least one sheet of the composite material wound over the filament-wound tube, and at least one strip of the composite material wound over the sheet of the composite material and forming a head on the composite mandrel. An internal cavity of the filament-wound composite tube may provide a lumen for the composite mandrel. The internal cavity may be threaded to receive a removable bridge plug.

    Abstract: A golf club shaft comprising a mandrel with a tapered surface as its outer circumference which is wound with three layers of prepreg sheets of high-strength fiber impregnate with synthetic resin. The middle layer is also wound with a separate string member. The inner layer fibers and the separate string member are arranged in a criss-cross pattern running generally in the longitudinal axial direction of the shaft. However, the fibers which are part of the middle and outer layers run unidirectionally only in the longitudinal axial direction of the shaft. No fibers run in a circumferential direction. In addition, the fiber and matrix of the outer layer become transparent after curing. Thus, even when the shaft is shrunk toward the center, no zigzag or wrinkles are generated in the string member found between the middle and outer layers nor in the outer layer fibers themselves. Also, no zigzagging, wrinkling, sagging or whitening occurs in the transparent outer layer which allows the design pattern of the string member to be seen. This increases the strength of the shaft and sufficient clamping stress by taping is provided. Finally, the safety of the club shaft is increased because the outer layer prevents exposure of the fibers and string member which decreases the chance of breakage.

    Abstract translation: 一种高尔夫球杆轴，其包括具有锥形表面作为其外圆周的心轴，其被三层用合成树脂浸渍的高强度纤维的预浸料片卷绕。 中间层也缠绕着一个单独的字符串成员。 内层纤维和单独的绳构件布置成大致沿轴的纵向轴向延伸的十字交叉图案。 然而，作为中间层和外层的一部分的纤维仅在轴的纵向轴向方向上单向运行。 没有纤维沿圆周方向延伸。 此外，固化后外层的纤维和基体变得透明。 因此，即使当轴向中心收缩时，在中间层和外层之间发现的绳构件中也不会在外层纤维本身中产生锯齿形或褶皱。 而且，透明外层中也不会出现锯齿状，起皱，下垂或变白，从而可以看到串构件的设计图案。 这提高了轴的强度，并提供了通过胶带的足够的夹紧应力。 最后，球杆杆的安全性增加，因为外层防止纤维和绳构件的暴露，这降低了破裂的几率。

    Abstract: A process for producing a reinforced plastic motor vehicle bumper includes the steps of placing a woven roving (17) on a center section of a preform screen (10) that is retained by a vacuum draw from a suction fan (16). Chopped glass fibers (20) and a curable binder are sprayed onto the preform screen and woven roving. A second layer (22) of woven roving is placed onto the center section of chopped glass and first layer (17) of woven roving. Either the excess trim (39) is trimmed by a cutting die (50) before the preform is cured or the die is first cured and then the excess trim is trimmed by a cutter using a plastic base (35) in the screen that circumscribes the contoured section of the preform screen.
