The present invention is to provide methods to increase composite interlaminate strength and interface strength, and make 3D fibers products, prepregs and composites, by using trans-interface and/or trans-fiber products such as trans-plies, strands and/or yarns fastening components selected from the group comprising of hooks and loops (velcro), hooks and hooks, zipper heads, fish hook shape hooks, staples, arrow heads, forks and mushroom heads. One ply of fibers has one or multiple of the above fasteners on at least one side. Lay-up the plies with said fastening components on its one or two sides to obtain a 3D fiber products with those fastening components locked together. The plies can be separated if need re-lay-up. A thread or a yarn have the fastening components around 0-360 degree on its surface. Lay the threads together or intercross each other to get a 3D fiber products. In those 3D fiber products, two parts of the fastening components lock each other if they meet and engage. A 3D composite can be made using the 3D fiber products.

One fiber ply with the fasteners on its at least one side, is impregnated or protruded with matrix materials, a piece of the prepreg with the fasteners prepreg with the fasteners are made. Lay and press the prepreg together fastening components will lock each other if they meet and engage. In most of production processes, the matrix materials might soften and meld, and the fastening components will further interlock each other. So a 3D composite structure is made by the said 3D prepregs. Those fastening components may stay just partially or fully in matrix at matrix surface. The fastening components increase the interface strength when two matrix materials meet just by crossing interface even if they are not locked and without fiber products in matrix.

The slider including a first surface and the panel including a second surface, the slider is being configured to be assembled to the panel with the first surface facing the second surface. The second surface is provided with an insertion groove and a displacement groove, which are of a longitudinal shape. A first angle, which is between the second surface and the insertion groove, is an acute angle. A strip protrudes from the first surface. A second angle, which is between the strip and the first surface, is an acute angle. The strip is configured to be inserted into the insertion groove when the slider is assembled to the panel. A displaceable tongue is arranged in the displacement groove. A locking surface of the displaceable tongue is configured to cooperate with a locking surface of the strip for locking the strip to the panel.

An electromechanical lock includes a latching assembly secured to a first structure, a catch piece secured to a second structure, and an electromechanical device. The latching assembly includes at least one latch element movable between a capture and release states to mechanically engage and disengage the catch piece, an arming member movable between a first and second positions wherein the latch element is released and captured, and a biasing element to urge the arming member into the first position. When the electromagnetic device is switched “on”, it magnetically engages the arming member with sufficient force to overcome the biasing force whereby movement of the catch piece away from the received state results in the latch element moving into the capture state to prevent separation of the first and second structures; when the electromagnetic device is switched “off”, the first and second structures may be separated.

A set including a panel and a slider, such as a drawer slider. The slider including a slider surface and the panel comprising a panel surface. The slider is configured to be assembled to the panel with the slider surface facing the panel surface. The panel surface is provided with an insertion groove and an undercut groove, which are of a longitudinal shape. A strip protrudes from the slider surface, and the strip is configured to be inserted into the insertion groove and the undercut groove by an angling motion.

The invention relates to a locking-unlocking device driven by two-stage redundancy, belonging to the technical field of locking and unlocking between two structures.

The guide bracket and the internal gear are sandwiched between the generally flat annular portion and the plurality of bent portions of the mounting ring, and an outer peripheral surface of the internal gear is held in sliding contact with an inner surface of the cylindrical side portion of the mounting ring, thereby radially positioning the internal gear.

A latch device includes a movable member and a housing. The movable member is urged with an urging member to a position where a part of the movable member projects from the housing. When the movable member is pushed into the housing against a force of the urging member, a push-push type lock mechanism turns to a lock state and the movable member is locked at a push-in position. When the movable member in the push-in position is pushed into the housing again against the force of the urging member, the lock mechanism turns to an unlock state, so that the movable member is returned to the projecting position. The lock mechanism is provided on front and back surfaces of the movable member as well as on portions of the housing facing the front and back surfaces of the movable member.
