Abstract
The purpose of the study is to predict the ballistic strength of rigid glass fiber/phenolic resin composites by using the full factorial experimental design. Ballistic glass/phenolic composites were made by the open mold high pressure, high-temperature compression of prepreg made of plain woven glass fiber fabric and polyvinylbutyrale modified phenolic resin.
The preparation of the composites was done by applying the 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 – 20/80 and 60/40, respectfully. We used the first-order linear model to approximate the response i.e. the ballistic strength of the composites within the study domain (9 – 2) kg/m2 x (20/80 – 60/40) ratio. The influence of each individual factor to the response function is established, as well as the interaction of the two factors. We found out that the estimated first-degree regression equation with interaction gives a very good approximation of the experimental results of the ballistic strength of composites within the study domain.
