TESTING ARRANGEMENT AND METHOD FOR COMPOSITE WITH NOODLE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18099634 titled 'TESTING ARRANGEMENT AND METHOD FOR COMPOSITE WITH NOODLE

The testing arrangement in this patent application involves a test specimen made of a fiber composite with three groups of fiber ply layers, each layer curved to form an elbow. These elbows are joined back-to-back at a central region to create three arms extending outwardly, with a space-filler within the central region.

  • The test specimen is mounted in a testing fixture for four-point bend loading on the first and second arms, while the third arm is oriented vertically.
  • An applied load is placed on the third arm, along with an actuated load to evaluate the mechanical behavior of the space-filler under stress.
  • The arrangement allows for testing the performance of the space-filler in a realistic loading scenario.

Potential Applications: - Testing and evaluating the mechanical properties of space-fillers in fiber composites. - Research and development in the aerospace and automotive industries for lightweight and high-strength materials.

Problems Solved: - Providing a realistic testing method for space-fillers in fiber composites. - Understanding the behavior of space-fillers under different loading conditions.

Benefits: - Improved understanding of the mechanical properties of fiber composite materials. - Enhanced design and performance of lightweight structures in various industries.

Commercial Applications: Title: Advanced Testing Arrangement for Fiber Composite Space-Fillers This technology can be utilized in industries such as aerospace, automotive, and construction for developing high-performance and lightweight materials.

Questions about the technology: 1. How does the testing arrangement in this patent application differ from traditional testing methods for fiber composites? 2. What are the specific advantages of using a space-filler in a fiber composite structure, as demonstrated in this patent application?


Original Abstract Submitted

A testing arrangement includes a test specimen that is formed of a fiber composite that has first, second, and third groups of fiber ply layers. Each fiber ply layer is curved so as to have an elbow. The elbows are joined back-to-back at a central region to form first, second, and third arms that extend outwardly from the central region. The elbows define a space in the central region, and there is a space-filler within the space. The test specimen is mounted in a testing fixture such that the first and second arms are in four-point bend loading and the third arm is oriented vertically. The testing fixture is actuatable to apply an actuated load. There is an applied load on the third arm. The applied load and the actuated load cause stress in the space-filler for evaluating mechanical behavior of the space-filler.
