    摘要: An active material based releasable fastener system for a vehicle carrier generally comprises a loop portion and a hook portion. A selected one of the hook portion or the loop portion is disposed on a surface of the carrier whereas an other selected one of the hook portion and the loop portion is disposed on a contact surface on which the carrier is disposed. When the loop portion and the hook portion are pressed together they interlock to form a releasable engagement being relatively resistant to shear and pull forces and weak in peel strength forces. The hook portion comprises a plurality of hook elements comprised of an active material. An activation signal applied to the active material causes a change in shape orientation, flexural modulus property, or a combination thereof to the hook elements that effectively reduces the shear and/or pull off forces in the releasable engagement. Disengagement of the releasable fastener system provides separation of the hook elements from the loop material under controlled conditions. In an alternative embodiment, each respective surface comprises a composite of the hook portion and the loop portion. Also disclosed is a process of operating the releasable fastener system for vehicle carriers.

    摘要: An airflow control device comprises a body and an active material in operative communication with the body. The active material, such as a shape memory material, is operative to change at least one attribute in response to an activation signal. The active material can change its shape, dimensions and/or stiffness producing a change in at least one feature of the airflow control device such as shape, dimension, location, orientation, and/or stiffness to control vehicle airflow to better suit changes in driving conditions such as the need for increased airflow through the radiator due to increases in engine coolant temperature. As such, the device improves vehicle fuel economy while maintaining proper engine cooling. An activation device, controller and sensors may be employed to further control the change in at least one feature of the airflow control device such as shape, dimension, location, orientation, and/or stiffness of the device. A method for controlling vehicle airflow selectively introduces an activation signal to initiate a change of at least one feature of the device that can be reversed upon discontinuation of the activation signal.

    摘要: A reconfigurable tool and/or die geometry and methods of use generally comprise forming at least a portion of a shape defining surface with a shape memory material. In response to an activation signal, the shape memory material changes geometry of the shape defining surface to provide a means for forming parts with different geometries from the same tool and/or die. In an alternative embodiment, an insert for a tool and/or die can be used, wherein the insert has at least a portion of its shape defining surface formed of a shape memory material. Also disclosed are processes for forming a first part with a defined geometry and a second part with a defined geometry different from the first part defined geometry using a reconfigurable tool and/or die as well as a reconfigurable insert with a standard tool and/or die.

    摘要: An active material hood impact mitigation mechanism is activated in response to a signal generated from an impact sensor or pre-impact sensor or manually. The mitigation mechanism is capable of changing either reversibly or irreversibly the stiffness, shape, location, orientation, or displacement force of the hood either globally or locally, before an impact against the hood. The active material mitigation mechanism is held in a device designed to be installed in operative communication with the hood surface. The active material is characterized by a first shape or stiffness and is operative to change to a second shape or stiffness in response to the activation signal. Such active materials include shape memory alloys, electroactive polymers, shape memory polymers, magnetic shape memory alloys, magnetorheological fluids, magnetorheological elastomers, electrorheological fluids, and piezoelectric materials.
