摘要： A releasable fastener system (10) comprises a loop portion (12) and a hook portion (14). The loop portion (12) includes a support (16) and a loop material (18) disposed on one side thereof. The hook portion (14) generally includes a support (20) and a plurality of closely spaced upstanding hook elements (22) extending from one side thereof, wherein the plurality of hook elements (22) comprises or incorporates a shape memory alloy fiber. When the hook portion (14) and loop portion (12) are pressed together they interlock to form a releasable engagement. The resulting joint created by the engagement is relatively resistant to shear and pull forces and weak in peel strength forces. Introducing a thermal activation signal (24) to the plurality of hook elements (22) causes a change in shape orientation, flexural modulus property, or a combination thereof that effectively reduces the shear and/or pull off forces in the releasable engagement. In this manner, disengagement of the releasable fastener system provides separation of the hook portion from the loop portion under controlled conditions. Also disclosed herein are processes for operating the releasable fastener system.

摘要翻译：可释放的紧固件系统（10）包括环部分（12）和钩部分（14）。环路部分（12）包括一个支撑件（16）和设置在其一侧的环形材料（18）。钩部分（14）通常包括支撑件（20）和从其一侧延伸的多个紧密间隔的直立钩形元件（22），其中多个钩形元件（22）包括或结合形状记忆合金纤维。当钩部（14）和环部（12）被压在一起时，它们互锁以形成可释放的接合。通过接合产生的所得接头相对于剪切力和拉力相对地抵抗，并且剥离强度力弱。向多个钩元件（22）引入热激活信号（24）导致形状取向，挠曲模量特性或其组合的改变，其有效地减少了可释放接合中的剪切力和/或拉拔力。以这种方式，可释放的紧固件系统的脱离提供了在受控条件下钩部分与环部分的分离。本文还公开了用于操作可释放紧固件系统的方法。

摘要： An impact absorbing device for a vehicle uses a shape memory material that can be heated to repair deformation from a relatively low speed, low energy impact and its stroking force and energy absorption can be tuned by heating. The shape memory material is suitably used in a crash box (14) having an inserted impact absorbing ram (16), the box being placed, for example, between a bumper (18) and strong body member. The shape memory material is attached to the box and ram for absorbing energy as the ram is driven into the box. Heating means is provided to repair or tune the shape memory material.

摘要： A releasable fastener system (10) comprises a loop portion (12) and a hook (14) portion. The loop portion includes a support (16) and a loop material (18) disposed on one side thereof. The hook portion generally includes a support (20) and a plurality of closely spaced upstanding hook elements (22) extending from one side thereof, wherein the plurality of hook elements comprises a first portion fabricated from a shape memory material and at least one additional portion fabricated from a different shape memory material. An activation device (24) is coupled to the plurality of hook elements, the activation device being operable to selectively provide an activation signal to the plurality of hook elements to change a shape orientation, a yield strength property, a flexural modulus property, or a combination thereof to reduce a shear force and/or a pull-off force of an engaged hook and loop portion. When the hook portion and loop portion are pressed together they interlock to form a releasable engagement. The resulting joint created by the engagement is relatively resistant to shear and pull forces and weak in peel strength forces. Introducing a suitable activation signal to the plurality of hook elements causes a change in shape orientation, flexural modulus property, or a combination thereof that is effectively reduces the shear and/or pull off forces in the releasable engagement. In this manner, disengagement of the releasable fastener system provides separation of the hook portion from the loop portion under controlled conditions. Also disclosed herein are processes for operating the releasable fastener system.

摘要： A releasable fastener system (10) comprises a male portion (12) and a female portion (14). The male portion (12) comprises a support (16) and at least one protrusion element (18) fixedly attached to the support. The female portion (14) comprises a support (20) and at least two parallel actuator strips (22,24) projecting from a surface of the support. The at least two parallel actuator strips (22,24) are spaced apart to form an opening equal to or less than a lateral dimension of the protrusion element (18). Each one of the at least two parallel actuator strips comprise a flexible strip and a piezoelectric material disposed on portions of the actuator strip. An activation device is coupled to the at least two actuator strips, the activation device being operable to selectively provide an activation signal to the piezoelectric material. In this manner, the shape of the actuator strips can be changed to provide a mechanical engagement of a frictional engagement of the male and female portions.
