DOGLAS describes a range of thermosetting, glass-fibre-reinforced plastics (GFRPs) that combine various resin systems (e.g. polyester, epoxide and others) with different laying patterns (glass fabric, roving fabrics and mats) to effortlessly overcome the diverse challenges of today's industrial companies.
DOGLAS materials obtain their properties both based on the choice of the resin system, and through the glass fibre structure in use. The plastic in use determines temperature stability, chemical resistance, heat conductivity, electrical insulation values, fire protection class and manufacturing costs. This may take the form of epoxide, polyester, copolymer, polyimide or silicon resins. The embedded glass fibre structure, e.g. short-fibre glass mats, fine or roving fabric, represents how the composite is constructed, as layer/laminate or quasi-isotropic, i.e. independent of the direction in terms of properties. The carrier material gives rise to further properties such as mechanical strength and setting behavior. The design-based degrees of freedom on custom-made parts are dependent on the carrier material, too.
