This document specifies the method for the characterisation of the compaction response of fibrous reinforcements used in liquid composite moulding. Specimens are compressed at a controlled speed to a predetermined thickness and the relative compressive load is measured. In this method, specimens are tested in both the saturated (“wet”) and unsaturated (“dry”) state. The following steps explain how to prepare the test setup and characterise the compaction response. This method specifies the speed of testing. It should be noted that testing at different speeds can yield different results which may not be comparable.

The standardisation of the test methods used to measure the out-of-plane permeability of fibrous reinforcements used in the manufacture of composite materials by liquid composite moulding. The test method details the equipment and procedure for measurement of the out-of-plane permeability, K3, at a known volume fraction.

This part of ISO 1268 specifies the general principles and procedures for the compression moulding of test plates from two types of fibre-reinforced thermosetting moulding compound: sheet moulding compound (SMC) and bulk moulding compound (BMC). The aim of this part of ISO 1268 is to ensure the preparation of flat test plates from which test specimens can be cut (for the relevant test methods, see Annex A). The plates are produced in such a way that specimens cut from them give representative results when used in these test methods.
