Speed of Ultrasound for Fiberglass:
The speed of ultrasound in fiberglass typically ranges between 2000 to 3000 meters per second (m/s), with a commonly cited average value around 2500 m/s. However, this is very subjective depending on factors such as:
1. Material Composition: The ratio of glass fibers to polymer resin (e.g., epoxy or polyester) affects the result. Glass fibers alone transmit sound faster (~5000–5500 m/s), while resins are slower (~2400 m/s).
2. Fiber Orientation: Fiberglass is often anisotropic, meaning the speed may differ depending on whether the ultrasound travels parallel or perpendicular to the fibers.
3. Manufacturing Process: Density, curing conditions, and voids/defects in the composite can alter the speed. The lower of density causing the higher of ultrasound speed that need to be set. Different resin causing different curing time indirectly causing different ultrasound speed form.
4. Temperature: Ultrasonic velocity may decrease slightly at higher temperatures.
For precise applications (e.g., non-destructive testing), it is recommended to:
- Measure the speed experimentally using a reference sample
(make your own one base on the actual ration of glass fibres to polymer resin & also the same method while building the fiberglass layer)
- Consult technical data from the fiberglass manufacturer.
