ASTM D7078
Engineered in compliance with ASTM D7078, the ACAD7078Y test fixture utilizes advanced hydraulic actuation to deliver consistent, evenly distributed gripping force for high-modulus fiber-reinforced composite materials. Designed to replace cumbersome manual fixtures, it significantly improves operational efficiency and testing reliability in aerospace, automotive, and materials research applications.
Overview
The hydraulically actuated test fixture is engineered to provide convenience, consistency, and efficiency when conducting tests in accordance with ASTM D7078 standards for understanding the shear properties of fiber-reinforced composites. In this test, a tensile force is applied to both ends of the specimen, generating concentrated shear stress in the middle section, where 90-degree notches are placed. Strain is typically measured using a ±45° biaxial strain gauge or a non-contact video extensometer.
Design Features and Benefits
Applications
Designed in compliance with the ASTM D7078 standard, this fixture is utilized to evaluate the shear properties of high-modulus fiber-reinforced composite materials (such as glass fiber, carbon fiber, etc.), which are critical in aerospace, aviation, automotive, and other industries. Traditional manual 7078 V-notched rail shear test fixtures are cumbersome to operate and inefficient. The new generation hydraulic 7078Y test fixture introduced by Lishi Corporation, with its rapid and precise operational performance, significantly enhances the efficiency of material evaluation. It can rapidly apply and measure shear loads, ensuring test consistency and providing reliable results. Consequently, this fixture is widely welcomed by research institutions, becoming an essential tool for improving research efficiency and accelerating material development.
