AN ESTIMATE OF THERMO-PHYSICAL CHANGES IN HYBRID BASALT/GLASS FIBRES REINFORCED POLYMER COMPOSITES

摘要

The paper aims to provide an insight into the thermo-physical changes of in-situ tailored hybrid polymer based composite materials based on two different synthetic reinforcements with the aim of sizing both architecture stacking sequences and reinforcement type's influence on their effective linear coefficient of thermal dilatation (CTE). The samples were subjected to a step ramp temperature increase up to 250 °C, followed by their CTE variation monitoring and assessment. Data processing and comparison further contribute to expand knowledge and appropriate personal database aiming material design, manufacturing error minimization and cost reduction.
