Abstract
In this study, a technological procedure for the production of a molding
compound based on short carbon fibers and an ablative phenol–formaldehyde
resin for high temperature application was optimized. The starting raw
materials were characterized and molding compounds with different fiber/
/matrix ratios and different fiber lengths were obtained. From the different laboratory
samples, molded parts were made by thermocompression. The basic
mechanical and thermal properties of the composites were determined. From
the obtained results, the optimal fiber/matrix ratio was determined for a production
of molding compound for high temperature application. The molding
process of the composite material was optimized and all the parameters for
good mechanical properties and high thermal stability of the composite were
obtained. Optimization of the composite molding process was performed by the
application of a numerical method for a planned experiment, i.e., a full three-
-factorial experimental design with variance of all three parameters (fiber length,
temperature and time of the press cycle) on two levels. The obtained mechanical
properties (flexural strength: 247 MPa, modulus: 27.6 GPa, impact resistance:
110 (for test moldings 10 mm10 mm) and 91 kJ/m2 (for test moldings
15 mm15 mm)) justified the application of this composite material in the
automotive, leisure, military and other industries where high temperature resistance
and high mechanical strength is required.
