ACG's LTM10 and 210 series prepreg tooling systems offer high temperature end performance after low temperature initial cure, minimizing dimensional and angular changes and providing cost effective materials for master model construction.  Step ahead cure technology, with temperature stability developing ahead of cure temperature, allows high temperature performance to be achieved after post cure without loss of stability or dimensional tolerance.

Product selection must balance initial cure temperature and product outlife to ensure that lay-up time and master model temperature resistance are not compromised.

Prepreg Description

All LTM® prepregs are designated by a reference code as shown in the example below:
