Effect of zeolite on glass fibre reinforced cyanate ester nano composites

Cyanate esters are thermally resistant thermosetting resins with low dielectric constant, low moisture absorption, high glass transition temperature and can be tuned for different mechanical, thermal and electrical properties. In this work, different compositions (0%, 1%, 3% and 5%) of zeolite nanoparticles incorporated cyanate ester composites were synthesised by Hand Lay-Up method followed by compression moulding. Curing was done at 200°C for half an hour. Mechanical properties like tensile strength, flexural modulus were measured using Universal Testing Machine. The thermal properties of the composites were studied by Thermogravimetric analysis (TGA). The decomposition occurred between 350°C to 400°C. The dielectric studies were carried out using LCR meter. All these studies supports that the chosen composite is a potential candidate for dielectric applications.
