Abstract: There are various ways to improve the properties of composites such as chemical treatment, plasma treatment, rare earth treatment etc. Using ionizing radiation is also one of the methods that can be used to improve the properties of the materials. The ionizing radiation could be from gamma radiation or Electron Beam Machine (EBM). However, focus is given on the effect of gamma radiation onto the composite materials. This paper provides a review on physical changes to composites after being irradiated with gamma radiation. The physical changes involved in the review were the tensile, flexural and compression properties. From the review, there exist the advantages after being irradiated to gamma radiation whereby the exposure to gamma radiation helps in improving the composites properties.
