Abstract
The purpose of the study is to assess the applicability of full factorial experimental design in
predicting the ballistic strength of glass fiber/phenolic ballistic composites. In the study we used a
number of ballistic composites (20 cm x 20 cm) with different thickness and fiber/resin ratio. The
composites were made by an open mold high pressure, high-temperature compression of prepreg
layers made of plain woven glass fiber fabric and polyvinyl butyral modified phenolic resin.
The preparation of the composite experimental samples was done in accordance to 22 full factorial
experimental design. The areal weight of composites is taken to be the first factor and the second
– fiber/resin ratio. The first factor low and high levels are 2 kg/m2 and 9 kg/m2, respectfully and for
the second factor – 80/20 and 50/50, respectfully. We used the first-order linear model with
interaction to approximate the response i.e. the ballistic strength of the composites within the
study domain (2 – 9) kg/m2 x (80/20 – 50/50) fiber/resin ratio. The influence of each individual
factor to the response function is established, as well as the influence of the interaction of the two
factors. We found out that the estimated first-degree regression equation with interaction gives a
very good approxi
