LI5102I 100J Instrumented Falling Weight Impact Testing Machine

The LI5102I 100J Instrumented Drop Weight Impact Test System is designed for ASTM D7136 composite panel impact testing, combining up to 100 J impact energy, high-speed data acquisition, single-impact control, and clear force–displacement–time analysis for material damage resistance evaluation.

Overview

The LI5102I 100J Instrumented Drop Weight Impact Test System is developed for evaluating the impact damage resistance of non-metallic materials, especially fiber-reinforced polymer matrix composite panels. It is suitable for both standard and non-standard plate specimens and is designed around the requirements of ASTM D7136/D7136M-15, the standard test method for measuring the damage resistance of composite materials under a drop-weight impact event.

During testing, the system captures the moment of impact through an instrumented striker and high-speed data acquisition. After the test, the software displays key curves such as force–time, force–displacement, displacement–time, velocity–time, energy–time, and energy–displacement, helping users understand how the specimen responds under impact loading. The system integrates mechanical structure, electrical control, PLC operation, PC software control, speed measurement, force measurement, and safety protection into one complete impact testing platform.

The LI5102I 100J is especially useful for laboratories that need reliable composite impact testing, repeatable single-impact results, and intuitive data analysis. Its transparent protective enclosure, secondary impact prevention system, ASTM-compliant fixture, and TestMaster control and analysis software provide a practical solution for research, quality control, education, and material evaluation.

Features

100 J Instrumented Impact Capacity
• The system provides an impact energy range from 3 J to 100 J, with adjustable striker mass from 2.0 kg to 10.0 kg in 0.5 kg increments. This allows users to configure impact conditions for different composite and non-metallic material specimens.
Single-Impact Integrity
• The secondary impact prevention system catches the striker after the first impact, helping prevent unintended repeated strikes caused by rebound. This supports more reliable single-impact test results and protects the integrity of the test process.
High-Speed Measurement and Data Acquisition
• The integrated force sensor, speed measurement system, and high-speed acquisition system record the short-duration impact event in real time. The system supports a sampling frequency of ≥200 kHz and provides force, displacement, velocity, and energy curves for detailed test analysis.
ASTM D7136 Fixture and Striker Configuration
• The specimen fixture is designed for ASTM D7136/D7136M-15 testing, with a support opening of 75 ± 1 mm × 125 ± 1 mm. The striker head uses a φ16 ± 0.1 mm diameter with SR8 ± 0.1 mm spherical curvature, supporting standardized composite panel impact testing.
Safe, Efficient Operation with PLC and Software Control
• The tester supports operation through both a touch-screen PLC control panel and PC software. The fully enclosed transparent protective shield, door safety interlock, height limit protection, and automated lifting and capture functions improve safety and workflow efficiency.
