Structure for combined composite material

Abstract

The invention discloses a structure for combined withing a composite material and belongs to the field of the composite material. The structure is an energy-conducting plate which is made of a macromolecular thermal plasticity polymer; extruded and gradually contracted pyramids are arrayed in a matrix form on the surface of the energy-conducting plate; the top ends of the pyramids are formed into sound-wave energy-gathering ends; the energy-conducting plate has a straight upper surface for lap-jointing an output end of a piezoelectric crystal; a sound wave can be outputted to a lower surface of the energy-conducting plate; and the downward contracted pyramids are arrayed in a rhombus matrix form on the lower surface of the energy-conducting plate and the top ends of the pyramids are formed into the sound-wave energy-gathering ends. The structure provided by the invention has the beneficial effects that due to the technology for enhancing the binding force, density and speed of the composite material, the structure can be applied to the therapy implements which have different physical properties and are to be isolated.

Description

technical field [0001] The invention relates to a structure combined with composite materials, which belongs to the field of composite materials. Background technique [0002] Plastics currently on the market are long-chain polymers formed from simple monomers through chemical polymerization. According to the definition of plastics by the American Plastics Industry Association: " Composed in whole or in part of carbon, oxygen, hydrogen and nitrogen and other organic or inorganic elements polymerized using heat, pressure, or both, liquid at a stage of manufacture and solid at the final stage of manufacture, such The large and varied group of materials is called plastics.” The process of processing high molecular polymers into plastic parts mainly includes the physical phase change of melting and solidification of thermoplastics or the chemical reaction of curing thermosetting plastics. [0003] Simple polymer materials have a chain structure. According to the difference in m...

Problems solved by technology

[0004] However, the author found that the density of the ultrasonic bonding is not uniform, the bonding speed is not fast enough, and there is still room for improvement in the bonding force. This is because the bonding surface of the high-molecular thermoplastic polymer has not been specially designed. , because when it is ultrasonically bonded to the same or dissimilar material with a flat surface, it cannot be melted and bonded simultaneously and uniformly, which is limited by the density of the material and the attenuation of the ultrasonic wave.
