Making flanged fibrous pipe composites commences with angled winding onto cores, forming layered structure, followed by end trimming and rotating to raise flanges, with assistance from external pressing molds defining final geometry

A layered structure (8) is wound on the shaft- (1) supported cores (2, 3, 4) at a winding angle of 5 deg -45 deg . End cores (3, 4) define the portions to be flanged, the center core (2) defining a substantially-unchanging region. Winding complete, the winding end-return regions are cut off at gaps (14). Gaps are formed by spacer washers (7) between discs (5, 6) and outer cores (3, 4). The central region of the composite is pressed by an outer collar mold acting against a stop, holding the composite both in place on the core, and to the correct dimensions. Before hardening, the assembly is rotated to lift the edges of the composite (e.g. centrifugally). These are further widened and pressed by end molds with stops, to define the final form of the flanges. An Independent claim is included for corresponding forming equipment.

Method of manufacturing a filament wound article

Elongate articles of non-circular cross section such as those of an airfoil cross section are constructed by winding filamentary material in layers about a form between a pair of spaced turnarounds generally conforming in shape to the cross sectional shape of the form. Adjacent layers are continuously wound by winding the filamentary material across the edges and outer face of each turnaround while reversing the direction of relative longitudinal displacement between the filamentary material and the form. The shape correspondence between the turnarounds and the form effect a minimization of expanse between the turnaround edge and form surface, thereby minimizing bridging of the filamentary material between those two members.

DEVICE FOR MAINTAINING A FIBROUS TEXTURE ON AN IMPREGNATION CHUCK OF A WINDING MACHINE

Pressure-cycled, packet-transfer infusion of resin-stitched preforms

A method and apparatus for manufacturing fiber-reinforced, composite materials relies on one or more processes improving over conventional forming, filling, and processing techniques. A homogeneous resin-stitching process provides for resin stitching for using only 5-20 percent of the rovings in a preform as wetted rovings, cured to maintain a stitching together of the structure. A resin-packet transfer process provides infusion of resins from directly beside a wall of a preform, rather than passing resins throughout the longitudinal length of fibers in a perform. A cyclic vacuum bagging process alternately applied over pressure and outside vacuum to a vacuum bag process, thus relieving pressure, and later, optionally, applying pressure to improve structural strength. Relieving pressure tends to improve (reduce) porosity.

Winding method for a composite band and apparatus for performing such method

Applying Resin for Fabrication of Plastic Pipe

Reinforced plastic pipe is made at high rates using a wiper 25 to remove resin from the surface of the rovings after they are applied to a rotating mandrel 10. The wiper comprising a plurality of parallel, spaced filament segments 105 leaves an optimum surface layer of resin on the rovings. For small diameter pipe, production rates are further increased by rotating the mandrel above its first critical speed. <IMAGE>

Armored multiple-layer plastic materials for manufacturing of printed circuits, methods for manufacturing of such materials and resulted devices

FIELD: microelectronics, in particular, manufacturing of substrates of printed circuits. SUBSTANCE: method involves generation of multiple-layer structure by means of parallel winding of dielectric threads on flat case, saturating this structure by binder in vacuum. Binder is either epoxy resin, polyimide, or polyester, or bis-maleic- imide or vinyl ether or phenol-aldehyde resin or melamine or polyphenylbutazone. EFFECT: increased functional capabilities. 57 cl, 35 dwg, 1 tbl 09108 0% ПЧ Го (19) 13) ВИ” 2080 750 ' МН 05 К 3/36 СЛ РОССИЙСКОЕ АГЕНТСТВО ПО ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ 12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ РОССИЙСКОЙ ФЕДЕРАЦИИ (21), (22) Заявка: 4613872/07, 10.09.1987 (71) Заявитель: Композитек, Лтд.
