A structural joint construction for connecting a first member of composite material to a second member which may be of composite material or of some other material. The construction enables tensile, compressive, torsional, and bending loads to be transmitted from the first member to the second member with a high degree of efficiency. One end of the first member is in abutting relationship with a free end of the second member such that a plurality of ends of first filament material integral with the core extends beyond its end and overlies the outer surface of the second member. The outer surface of the second member is contoured to include a central portion of minimal cross-sectional area bounded by opposing portions of greater cross-sectional areas. Other filament material is wrapped around the first filament material in a direction transverse to the axes of the first and second members such that the ends of the first filament material conform to the contour of the outer surface of the second member and are held fast to the second member.
A coupling comprising a tube made of plastic composite material to be used as a structural member and having an end portion formed with a plurality of acute cutouts, a fitting having a small-diameter front end portion and a bell-shaped tapering rear portion, and a bell-shaped sleeve having an inner wall surface of a shape corresponding to that of the tapering portion of the fitting. The end portion of the plastic tube is held between the fitting inserted into the end portion and the sleeve mounted on the outer periphery of the taper fitting, and a nut threadedly engaged with external threads of the fitting is tightened to assemble the fitting, the plastic tube and the sleeve as a unit.
A structural member capable of transmitting both tensile and compressive forces is made up of a first component and a second component each capable of transmitting the load which the structural member is designed to carry. The first component is formed of a structural metal while the second component consists of fiber-reinforced synthetic plastic material fibers wound on the first component in the elongated direction of the structural member. If the first component fails, then the second component made up of the longitudinally wound fibers can take over the transmission of the designed load.
An improved tubular composite for transmitting substantial thrust forces has a tubular core of continuous reinforcing fibers in a resin matrix unidirectionally and longitudinally oriented. Integral with the core is a sheath of resin impregnated continuous fibers oriented at about .+-.40.degree. to about .+-.60.degree. with respect to the longitudinal axis of the core.
4183261 - Shackle - Owned by Messerschmitt-Bolkow-Blohm GmbH (Munich,DE)
The present shackle is especially constructed for securing a wing to the fuselage of an aircraft or of a spacecraft. For this purpose the elements of the shackle intended for taking up pressure and tensile forces as well as the elements providing the necessary structural stability are made of fiber compound materials such as carbon or boron fibers.
Window shade structure for reducing heat loss or heat gain through a window or other "thermal opening" wherein the shade body is drawable over the window and is collapsible into a reduced storage volume. The shade body comprises opposed walls of thin, sheet-like layers of flexible and resilient material joined together along spaced parallel adhesion lines to form a plurality of contiguous and parallel channels in the shade body. A strip-like sealing slat on the surfaces of the window frame which oppose the edge portions of the shade body, and a slot-like recess formed in the opposite edges of the shade body and extending the full length thereof receive the edge portions and portions of the lateral surfaces of the sealing slat, with the free edges of the sheet-like layers being flexed against the lateral surfaces of the sealing slat to insure against convective air flow and provide an effective convective seal.
