2024-09-13 Bioinspired basalt fiber composites with higher impact resistance through coupling sinusoidal and helical structures inspired by mantis shrimp doi:10.57760/sciencedb.13341 en After the manufacturing of biomimetic composites, the sample is also cut by the universal prototype with grinding wheel for impact experiment. The test sample adopts the non-notched sample, according to the corresponding non-notched sample standard according to standard ISO 180:2000. The test instrument used is JJ-20 pendulum impact tester. The length, width and thickness of the sample are 80mm, 10mm and 4mm, respectively. Each group tests 5 parallel samples, and the average value is taken. After impact, the impact toughness is calculated through the formula. Composite laminate; Impact resistance; Helical structure; Sinusoidal structure.
