COMPOSITE PANEL INCLUDING A TAILORED COMPOSITE CORE VIA ADDITIVE MANUFACTURING - A simplified explanation of the abstract

This abstract first appeared for US patent application 17836056 titled 'COMPOSITE PANEL INCLUDING A TAILORED COMPOSITE CORE VIA ADDITIVE MANUFACTURING

Simplified Explanation

Abstract

A composite panel is described in this patent application. The panel consists of two outer layers (skins) and a core in between them. The core is made up of multiple zones that are 3D printed using a thermoplastic material. Each zone is connected to the adjacent zones and has a different density. The variables Z and D represent the number of zones and the density levels, respectively.

Patent/Innovation Explanation

  • The composite panel consists of two skins and a 3D printed core.
  • The core is made up of multiple zones that are connected to each other.
  • The zones are 3D printed using a thermoplastic material.
  • Each zone has a different density, and the number of zones and density levels can be adjusted.

Potential Applications

This technology has potential applications in various industries, including:

  • Aerospace: Lightweight and strong composite panels for aircraft interiors and structures.
  • Automotive: Durable and customizable panels for car interiors and exteriors.
  • Construction: Insulated panels for buildings with different density zones for improved structural integrity.
  • Marine: Water-resistant panels for boat interiors and hulls.

Problems Solved

This technology addresses several problems in the field of composite panels:

  • Weight reduction: The use of 3D printed thermoplastic zones allows for lightweight panels without compromising strength.
  • Customization: The ability to adjust the number of zones and density levels provides flexibility in panel design.
  • Improved structural integrity: The connection between zones and the variation in density levels enhance the overall strength of the panel.

Benefits

The benefits of this technology include:

  • Lightweight panels that can contribute to fuel efficiency and cost savings.
  • Customizable designs to meet specific requirements and aesthetic preferences.
  • Enhanced strength and durability due to the connection between zones and variation in density levels.
  • Potential for cost-effective production through 3D printing technology.


Original Abstract Submitted

A composite panel comprises a first skin and a second skin. A core is arranged between and attached to the first skin and the second skin. The core includes Z zones that are 3D printed using a thermoplastic material. Each of the Z zones abuts and is connected to another one of the Z zones. Each of the Z zones has one of D densities and at least one of the Z zones had a different density that another one of the Z zones. Z and D are integers greater than one.
