## Description

- description: "We conducted an in situ study on CFRP fracturing process using atomic-force-microscopybased
    stress-sensitive indentation. Tensile stress distribution during fracture initiation
    and\r\npropagation was directly observed quantitatively. It led to a discovery
    that previously believed\r\ncatastrophic fracture of individual carbon fiber develops
    in a controllable manner in the\r\npolymer matrix, exhibiting 10 times increase
    of fracture toughness. Plastic deformation in\r\ncrack-bridging polymer matrix
    was accounted for the toughening mechanism. The model\r\nwas applied to explain
    low temperature strength weakening of CFRP bulk material when\r\nmatrix plasticity
    was intentionally ‘shut down’ by cryogenic cooling."
