Geng Liangfu to support us again. Impact resistance is a critical measure of service life and more importantly these days, it involves the perplexing problem of product safety and liability.

The potential energy of the drop-weight, as defined d71366 the mass and drop height of the impactor, is specified prior to test. Contact Us View Accessories Catalog. WANCE products have a good quality.

1800J Drop Impact Test Machine For Composite Materials Testing ASTM D7136

Rotary encoder is used for measurement of height. Shenzhen Wance Testing Machine Co. With impact energies ranging from 1. To prevent a secondary impact of the falling weight onto the composite plate we employ our anti – rebound device. Sample Making Machine However, it must be understood that the damage resistance of a composite structure is highly dependent upon several factors including geometry, thickness, stiffness, mass, support conditions, and so forth. One piece of information that may not be found without the use of instrumentation is the first crack or incipient damage point.

For example, properties obtained using this test method would more likely reflect the damage resistance characteristics of an unstiffened monolithic skin or web than that of a skin attached to substructure which resists out-of-plane deformation.

Servo Hydraulic Universal Testing Machine Knowledge of the damage resistance properties of a laminated composite plate is useful for product development and material selection. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Striker assembly Striker assembly consists of guide sleeve, striker, force transducer and tup.
