Abstract
Polymers are characterised with lightness, ease of formability and resistance to
chemical attack but their modulus and strength are low. Epoxy was reinforced with
aluminium particles of different sizes. Bond, functional group and chemical formulae of
the composite phases were examined using Fourier Transform Infrared Spectroscopy
(FTIR) and X-ray diffractometer. The flexural test was also conducted on the developed
composites via three-point method. Analysis of variance (ANOVA) was performed using
aluminium percentage by weight (wt%) and sizes (Ps) as the predictor variables. Results
indicated different chemical formulae of the composite phases. A maximum of 124.44 %
increase in flexural modulus was found at 12 wt% reinforcement addition. Probability
value, 0.000 for each of wt% and Ps affirm evenly significant influence of both variables
on flexural modulus of the composites. Hence, the developed multiple regression model
can be used for predicting the flexural modulus of epoxy particulate composites within
and outside the scope of experiment
