Abstract

Phenolic resins are known for their excellent thermal properties and chemical stability and are widely used in automotive industry, electrical engineering, military industry and industry of construction materials. Their attractive properties have been especially exploited in high temperature applications. Recently a wide range of phenolic resins for different applications is available on the market. In this paper the properties of two types of ablative phenolic resins are compared: resin BD5 of resole type, modified with thermoplastics and dissolved in methanol and phenolic resin DV30 dissolved in isopropanol. In order to determine the processing conditions, emphasis is placed on such characteristics as B-time, solid content and viscosity. Thermogravimetric analysis (TGA) of the resins were also carried out, and heat deflection temperature of the phenolic composite was determined according to Marthens method. Phenolic composites have good physical and thermal properties and are superior compared to many other materials in regard of their inherent thermal resistance, low smoke and application in high fire risk areas. Based on the obtained results on thermal characteristics of the resins, the appropriate resin has been chosen for the production of composite material for special high temperature application in "Eurokompozit".
