Fiber reinforced plastic materials are able to be customized according to the application and behavior of materials. In this work, the effect of meticulous nanoclay, Cloisite 20B, inclusion (with various concentrations) on the interlaminar fracture toughness glass fiber reinforced plastic (GFRP) composite was experimentally investigated. The mode-I tests were conducted based on a double cantilever beam (DCB) tests using American society of testing materials (ASTM D5528). Results showed that the inclusion of nanoclays improved the interlaminar fracture toughness of the GFRP composite in the range of 12.65% and 54.07% relative to the pristine, with a progressive increment of the nanoclays weight by percentage content (from 0.5 to 2%). The research provides a better understanding of Cloisite filler's contribution in improvement of the delamination resistance and the outcome can guide to a design of better melt flow rate and good elongation at break of flame for structures, which is made up of composite materials.

纤维增强塑料材料可以根据材料的应用和行为进行定制。在这项工作中，通过实验研究了精细纳米粘土 Cloisite 20B 夹杂物（不同浓度）对层间断裂韧性玻璃纤维增​​强塑料 (GFRP) 复合材料的影响。模式 I 测试基于使用美国测试材料协会 (ASTM D5528) 的双悬臂梁 (DCB) 测试进行。结果表明，纳米粘土的加入使 GFRP 复合材料的层间断裂韧性相对于原始材料提高了 12.65% 和 54.07%，纳米粘土的重量百分比含量逐渐增加（从 0.5% 到 2%）。该研究提供了对 Cloisite 填料的更好理解
