ISO 14125 — Flexural Properties of Fibre-Reinforced Plastic Composites

ISO 14125 · ISO standard

ISO 14125 is the test method for the flexural properties of fibre-reinforced plastic composites. To match this to your program, talk with our team.

What ISO 14125 Covers

It determines flexural strength and modulus of FRP laminates using three- or four-point bending, aligned with the international framework.

How the Test Is Run

A composite bar is loaded in three- or four-point bending at a controlled rate, and flexural strength and modulus are calculated from the load-deflection curve.

Why It Matters

Flexural properties are a core composite metric; a rigid fixture and accurate deflection measurement keep results comparable.
