The University of Auckland, New Zealand, has installed an Imatek IM10T-20 impact tester, which will be used to test polymer composite materials.

The university has eight faculties and it supports a number of research centres and institutes.

The Centre for Advanced Composite Materials (CACM), which was established in 2002, is a joint venture between the University of Auckland, SCION (Forest Research) and other industrial participants utilising government research funding.

The goal of the centre is to conduct research into advanced composite materials and manufacturing processes.

The centre, directed by Prof Debes Bhattacharyya, has pioneered the development of polymer and composite materials – a polymer-polymer composite made by blending and processing two recycled plastics.

This product has a wide range of applications in manufacturing, biomedical areas and packaging, particularly for products that have limited shelf life.

The IM10T-20 has a 2m drop height and offers standard impact velocities within the range of 1m/s to 6.26m/s and up to 20m/s with the optional high velocity system.

Impact energy is in the range 2.5J to 588J for the standard machine, rising to 2,000J with the high velocity system.

Options selected by the University of Auckland included: the high velocity system; hemispherical strikers and anvil clamping to enable testing to the requirements of ISO6603; Imatek’s stripper system for automated removal of tough/ductile specimens from the striker; and second impact prevention (SIP).

The machine was also fitted with a removable temperature conditioning chamber, dynamic displacement system for direct measurement of mass displacement during specimen impact, a Film Testing Kit (for ASTM -D1709A, D1709B and D4272 methods) and a compression after impact (CAI) kit for testing to the requirements of ASTMD7136 and ASTM D7137.

The University of Auckland will also be using Imatek’s integrated high-speed video option that combines data captured by the IM10 during the impact test, together with high-speed video imagery.

A video sequence provides a great deal of qualitative information about a test event and the software also allows quantitative information to be extracted.
