In forming a structural part or a support, the lattice-type structure can be cut into sectors or other shapes with the shapes being joined together, if necessary, to provide the desired finished configuration.SUMMARY OF THE INVENTIONThe present invention is directed to a lightweight structural part formed of carbon fiber-reinforced plastic which is constructed from carbon fiber rovings wound on a mandrel and subsequently processed by pressing.Carbon-fiber-reinforced plastics are used for structural parts which must have a high rigidity and a very low specific weight.

Abstract: At least one conductive metal foil is preliminarily bonded to an electrically insulating resinous substrate by squeezing the layers together under heat and pressure in a continuous mode, as by passing the layers through a nip roll to produce a partially cured resinous layer subjacent to the metal foil. The thus preliminarily bonded laminate is further processed in an autoclave, under heat and pressure, whereby the bonding layer between the metal and the substrate is cured. The laminate formed by this process is useful for metal-clad boards, particularly printed circuit boards. These boards may be either flexible or rigid.

Abstract: A high temperature tape for use in protecting a structural item to be subjected to high temperature, and the method whereby this novel tape is made are set forth. The tape is principally constituted by a number of elongated carrier fibers disposed in an essentially aligned array, and a large number of comparatively short fibers disposed in a nonwoven manner essentially transversely to the elongated fibers. The short fibers typically extend beyond the confines of the carrier fibers, at least on one side, thus to create a pliable, fringed tape capable of being wrapped for a number of turns about an item to be protected. This wrapping may be done in such a manner that the fringe formed by the short orthogonally placed fibers is available to extend over and cover previous turns of the tape. The fibers are of temperature resistant material, and various means are provided for securing the short fibers to the elongated fibers, including the use of certain resins.

Abstract: A wound roll of filmstrip of the type having a photographic emulsion layer on one strip face and a raised stripe disposed along one edge of the opposite strip face is so formed as to produce temporary adhesion between the stripe of one convolution and the emulsion layer of an adjacent convolution. Such adhesion or tacking, restricts relative movement of the convolutions, thereby avoiding effective axial expansion of the roll and the resultant generation of undue frictional forces during advancement of the strip through a cartridge in which is is housed.Such tacking may be achieved by forming the strip into a roll and by so applying energy to a flat end face of the roll as to cause localized melting of the emulsion layer of one convolution at its interface with the raised stripe of an adjacent convolution, whereupon subsequent cooling and rehardening of the emulsion produces adhesion of the convolutions at such interface.
