Characteristics on Trimming of GFRP.

Journal of the Japan Society for Precision Engineering, 1991
GFRP, because of their superior strength-to-weight and stiffness-to-weight ratio, are used increasingly in high-performance applications. But the users of this material have faced a difficulty to machine them. The major trouble in cutting GFRP is the decreased tool-life, the inferior surface quality and others.

Hybrid Steel/NSM/GFRP System Versus GFRP Wrapping for Upgrading RC Wall-like Columns

Polymers, 2023
Reinforced concrete (RC) wall-like columns are commonly employed in structures in Saudi Arabia. These columns are preferred by architects owing to their minimum projection in the usable space. However, they often need strengthening due to several reasons, such as the addition of more stories and increasing the live load as a result of changing the ...

Mechanical Behaviour of Vacuum‐Infused GFRP Composites at Elevated Temperatures—Influence of Fibre Architecture

Fire and Materials, EarlyView.
ABSTRACT This study addresses the influence of fibre architecture on the mechanical properties of vacuum‐infused glass fibre reinforced polymer (GFRP) composites at elevated temperatures (ET). Laminates with three different fibre configurations—unidirectional (UD), bidirectional 0°/90° cross‐ply (BD), and ±45° off‐axis angle‐ply (OA) – were tested in ...
