Mechanical property of UV curable glass fiber fabric/EP PBMA resin composites

The epoxy-poly(butyl methacrylate) (EP-PBMA) resins which can be polymerized and cured by UV and thermal initiation were designed.Based on the EP-PBMA resin, UV curable glass fiber fabric/EP-PBMA composites were prepared.The tensile properties of the glass fiber fabric/EP-PBMA composite samples with different mass ratios of EP to PBMA were tested under different loading rates.According to the results, glass fiber fabric/EP-PBMA composites have a obvious strain rate effect.With the increase of loading rate, the tensile strength and elastic modulus increase.The composition of EP-PBMA resin matrix can affect the strain rate effect greatly.When the loading rate is low, glass fiber fabric/EP-PBMA composites perform better tensile strength than the composites of pure EP matrix.However, when the loading rate reaches 50 mm/min, the tensile strength of glass fiber fabric/EP-PBMA composites becomes lower.
