  • Balance between bonding and deposition during

    2019-7-16 · As the tensile load increases, the separated fibers resist the load and exhibit high toughness. However, these fibers do not break at the same time, which leads to ruptured fibers of uneven length. As a result, the stress gradually decreases with increasing strain, which may not be beneficial to most practical applications.
