Description

Combining GRP (fiber reinforced plastic) sheets and aluminum sheets has multiple advantages, which are reflected in the following aspects:

Strength and stiffness: GRP sheets have high strength and good fatigue resistance, while aluminum sheets provide good stiffness and compressive strength. Combining the two results in composites with higher strength and stiffness.
Lightweight: GRP sheets and aluminum are both lightweight materials, and their combination helps reduce the weight of the overall structure, which is especially suitable for weight-sensitive fields such as aerospace, automotive and construction.
