Impact Resistance of Composite Materials - Nautical Applications
Resins, and composites with a resin matrix, provide materials that are strong, lightweight, corrosion-resistant and dimensionally stable. These materials also provide good design flexibility, a high dielectric strength, and usually require lower tooling costs. Their tremendous strength-to-weight and design flexibility make them ideal in nautical applications.
They are widely used in the building of recreational boat hulls and products destined to permanent water contact such as competition boats, surf-boards etc. Manufacturers of these products require materials that have a high degree of resistance to impact.
Of concern to the manufacturer not only is any damage that may be done to the outer layer of the product, but any damage that may occur to the inner layers of the material due to the impact event. The best way to investigate the impact properties of a resin or a composite based on resin matrix is to perform fully instrumented impact tests. Gathering data from this type of testing allows for the investigation of how all layers of the material react to impact events of varying energies.
The tests are commonly carried out according to ASTM D3763 or ISO 6603-2. To meet the requirements for this application, we recommend our CEAST 9350 Series, coupled with the proper specimen clamping set, anti-rebound device, multiple crossheads, instrumented tup, tup insert, DAS and Visual Impact software. Because materials may react differently to an impact event based upon the temperatures they are used at a thermostatic chamber may also be required.

CEAST Data Acquisition and Analysis
The new CEAST DAS 64K is a state-of-the-art Data Acquisition System designed for impact testing instruments. Compatible with the full range of CEAST impact testing systems, including pendulum type machines (CEAST 9000 Series) and drop towers (CEAST 9300 Series), it’s the key for instrumented impact testing. The DAS 64K also enables the data collection from instrumented tups or hammers on older models and non-CEAST impact machines.

CEAST 9300 Series
Impact resistance is one of the most important properties for component designers to consider, as well as the most difficult to quantify. Impact resistance is a critical measure of service life and more importantly these days, it involves the perplexing problem of product safety and liability. With the combined experience of Dynatup® and CEAST, Instron® has more than 80 years experience in designing impact testing systems to simulate real-life impact conditions.
