Analysis of the damaged area due to ballistic impact was carried out on fiberglass/polyester bi-panel composites with tapioca starch as a filler. The Bi-Panel composite consists of two panels with a thickness of 4 mm each. Each panel consists of unsaturated polyester resin BQTN 157 and reinforced with constant volume of woven roving S-glass and variation of tapioca starch of 40% and 50% vol. as a filler. The characterization has been done by means of Fourier-transform infrared (FTIR) spectroscopy, x-ray diffractometer (XRD) and impact test with calibre ammunition of 9 mm bullet FN gun. The results showed the influence of tapioca starch on the strength of composite panels against the high impact of a bullet.
