ASTM D790

Engineered in accordance with ASTM D790, our three-point flexure fixture is designed to determine the flexural properties of unreinforced and reinforced plastics, high-modulus composites, and electrical insulating materials. Built with premium stainless steel and featuring high-strength 440C stainless steel anvils, it offers exceptional durability and corrosion resistance. Equipped with a built-in specimen centering device, it ensures quick and accurate testing. When paired with a dial indicator or deflectometer, it provides precise measurements of flexural strength, strain, and modulus — making it an indispensable tool for material R&D and quality control.

Overview

Engineered in accordance with ASTM D790 standards, this three-point flexure fixture is designed for testing the flexural properties of unreinforced and reinforced plastics, as well as high-modulus composite materials. It provides a reliable and precise testing platform for evaluating material behavior under bending loads.

Design Features and Benefits

Specimen Centering:
Equipped with a built-in positioning device to ensure quick and accurate specimen centering, significantly improving testing precision and operational efficiency.
Durable Construction:
The base is constructed from premium stainless steel, while the loading anvils are made of high-strength 440C stainless steel. This combination provides excellent corrosion resistance and exceptional durability, ensuring the fixture maintains optimal performance over long-term use, regardless of environmental factors.

Applications

Primary Purpose:
Primarily used for measuring the flexural properties of unreinforced and reinforced plastics, high-modulus composites, and electrical insulating materials. The test involves placing a rectangular specimen on two support anvils and applying a load through the upper loading anvil until the outer surface of the specimen breaks or a maximum strain of 5.0% is reached.
Advanced Measurement:
When paired with a dial indicator or deflectometer, it can accurately measure flexural strain and flexural modulus, providing robust data support for material R&D, quality control, and performance evaluation.
