摘要： A tubular body (1) made of a fiber-reinforced plastic and used as a structural material of a vehicle includes corners (4) extending along an axis of the tubular body (1) on an outer circumferential surface thereof. The tubular body (1) is a tubular laminate that is formed by laminating a fabric layer (12) formed by laminating fabric materials and unidirectional material layers (11, 13). Each fabric material includes a fabric in which reinforcing fibers are woven and a plastic with which the fabric is impregnated. Each unidirectional material layer (11, 13) includes reinforcing fibers oriented in one direction and a plastic with which the reinforcing fibers are impregnated. The reinforcing fibers of each unidirectional material layer (11, 13) are oriented along the axis of the tubular laminate. The unidirectional material layers (11, 13) include an outer unidirectional material layer (13) laminated on an outer circumferential surface of the fabric layer (12), and an inner unidirectional material layer (11) laminated on an inner circumferential surface of the fabric layer.

摘要： To suppress deformation of a vehicle cabin by efficiently absorbing an impact load obliquely from a vehicle front side, a vehicle-body front structure includes an upper-side cross member, a lower-side cross member, upper-side impact absorption members that support respective ones of both vehicle-width-direction sides of the upper-side cross member, and lower-side impact absorption members that support respective ones of both vehicle-width-direction sides of the lower-side cross member. The upper-side impact absorption members and the lower-side impact absorption members are each positioned farther on a vehicle-width-direction outer side at a position farther on a vehicle front side.

摘要： To suppress damage on a bonnet at light collision, a vehicle-body structure includes rear-portion crush cans that perform compressive deformation when a first predetermined load is applied, and front-portion crush cans that perform compressive deformation when a second predetermined load smaller than the first predetermined load is applied. A front portion of a bonnet is positioned on a vehicle rear side of front portions of the rear-portion crush cans.

摘要： There are provided an outer panel, an inner panel, a second reinforcement provided in the main closed-cross section and cooperates with the outer panel to form a sub closed-cross section extending longitudinally, a bead portion formed at a portion of the inner panel which is located at a position corresponding to the second reinforcement, and configured to be a starting point causing bending of a front side frame toward the second reinforcement when a collision load is applied in a vehicle collision, and a second attaching member provided at a position located on a front-end side of the front side frame relatively to the second reinforcement and configured to make the second reinforcement crushable in a bending direction in the vehicle collision. The second attaching member comprises a knot-shaped member provided inside the main closed-cross section.
