Inflatable-Based Process for Controlling Structural Foam Reinforcement Molding - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240051606 titled 'Inflatable-Based Process for Controlling Structural Foam Reinforcement Molding

Simplified Explanation

The patent application describes a structural component for a vehicle that includes an interior surface defining a hollow passage and a structural reinforcement that contacts the interior surface. The structural reinforcement partially fills the cross-section of the component. The process for forming the structural component involves inserting a bladder into the hollow passage, inflating the bladder to create a cavity between the bladder and the interior surface, filling the cavity with a polymer resin, and foaming the resin. The system for forming the structural component includes the component with a hollow passage, a bladder insertable into the hollow passage, and a supply line connected to the bladder.

  • The patent application describes a structural component for vehicles that includes a hollow passage and a structural reinforcement.
  • The structural reinforcement contacts the interior surface of the component and partially fills the cross-section.
  • The process for forming the structural component involves inserting a bladder into the hollow passage, inflating it to create a cavity, filling the cavity with a polymer resin, and foaming the resin.
  • The system for forming the structural component includes the component, a bladder, and a supply line connected to the bladder.

Potential applications of this technology:

  • Automotive industry: The structural component can be used in various vehicle parts, such as body panels, frames, and chassis, to provide enhanced strength and rigidity.
  • Aerospace industry: The technology can be applied to aircraft components to improve structural integrity and reduce weight.

Problems solved by this technology:

  • Enhanced strength: The structural reinforcement and foamed polymer resin provide increased strength and rigidity to the component, improving its overall structural integrity.
  • Weight reduction: The foamed polymer resin helps reduce the weight of the component without compromising its strength, leading to improved fuel efficiency and performance.

Benefits of this technology:

  • Improved safety: The enhanced strength and rigidity of the structural component contribute to improved safety in vehicles and aircraft.
  • Cost-effective manufacturing: The process of forming the structural component using a bladder and polymer resin can be automated, resulting in cost savings during production.
  • Design flexibility: The technology allows for the creation of complex shapes and designs, providing greater design flexibility for vehicle and aircraft manufacturers.
