PRE-CONSOLIDATED PRE-FORM AND METHOD OF PRE-CONSOLIDATING PRE-FORMS

摘要

A pre-consolidated pre-form and a method of pre-consolidating pre-forms are provided. Pre-consolidation is a process, whereby gas inside a pre-form is removed and a low porosity is produced. It involves redistribution of resin and optionally a redistribution of fibres. The pre-consolidation may involve a limited curing of the resin. Pre-consolidated pre-forms and composites prepared from pre-consolidated pre-forms will be appreciated amongst others due to good reproducibility, low porosity, high homogeneity, high strength, ability to plastically shaping of the pre-consolidated pre-form, ability to be connected to other pre-forms and/or other structures, suitability for automation and long shelf life without premature curing.
