Disclosed embodiments provide automated fiber placement techniques for fabrication of parts made from composite materials. A peening system with multiple pins provides compaction over irregular surfaces, providing superior performance as compared with traditional compaction rollers. The apparatus that carries out the techniques include a tape dispensing system, a heating system, a peening system, a processor and a memory coupled to the processor. The memory contains instructions that when executed by the processor perform the steps of: dispensing a first ply of thermoplastic composite tape over a mandrel; dispensing a second ply of thermoplastic composite tape on the first ply; and peening the second ply onto the first ply, such that the second ply is bonded to the first ply.

The present invention is directed to tack solutions comprising formic acid, and their use in applying adhesive-coated films to substrates. In particular, paint protection films (PPFs) can be applied to vehicle bodies using the solutions of the present invention.

A production line for producing components to a high standard of cleanliness and sealed and protected in that state includes a loading device, a cleaning device, a detecting device, a pasting device, a heat-sealing device, a packing device, and transfer devices of the production line. The production line automatically processes the components for obtaining components with the high cleanliness. By the processes of protective film pasting, heat-sealing, and packing, the components may be further protected from subsequent pollution. A method for producing components with a high cleanliness applied to the production line is also disclosed.

A device for preparing a liner to be installed in a pipe. the device comprising a top part having rollers extending between top sides and having a top belt arranged on rollers. The device further comprises a bottom part having rollers extending between bottom sides and having a bottom belt arranged on the bottom rollers. One of the bottom rollers is a pulley roller driving the bottom belt when rotated. At least one roller of the top rollers is movably attached to the top sides, and at least one roller of the bottom rollers is movably attached to the bottom sides.

A blade for a hockey stick which can readily absorb impact from the puck, and can allow the user to feel the puck on the blade in contrast to conventional carbon fiber blades. The blade can include a blade member integrally formed of composite material having discontinuous fibers bonded within thermosetting resin. The blade member can have a blade periphery surrounding a central blade region. The central blade region can have a plurality of openings arranged in a pattern to form series of elongate criss crossing ribs that extend between and connect different sides of the blade periphery to each other. The fibers in the blade periphery can be in a generally jumbled orientation, and the fibers in the central blade region can be positioned within the ribs in a manner wherein each rib contains a plurality of fibers that substantially extend in said each rib's elongate direction.

A method and an apparatus for coating a solid wood floor and a solid wood floor are provided. The method for coating a solid wood floor includes providing a solid wood floor, where the solid wood floor has two side surfaces defining boundaries of a width dimension of the solid wood floor; and providing a polyethylene protective film, and adhering the polyethylene protective film to at least one of the two side surfaces. Therefore, external moisture can be prevented from entering the solid wood floor so as to avoid deformation of the floor due to moisture; an external dust, water, etc. can be prevented from entering between two adjacent solid wood floors; an overall appearance of the laid solid wood floors will not be affected by the coating; when the laid solid wood floors are subjected to force, no noise will be emitted, thereby improving customer satisfaction.

A tube used or medical or other purposes is concentrically bonded to an inner lining tube by sequentially inserting a core within the inner lining tube, creating an adhesive layer on the outer surface of the inner lining tube, inserting the inner lining tube and core into the lumen of the outer tube, and then activating the adhesive to bond the inner tune to the outer tube before removing the core.
