具体实施方式
本发明实施例提供了一种激光冲击层裂缺陷的超声检测方法及装置，用于解决现有技术中存在复合材料的粘合界面的潜在缺陷或者处于临界状态的缺陷无法检测出来的技术问题。
为使得本发明的发明目的、特征、优点能够更加的明显和易懂，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，下面所描述的实施例仅仅是本发明一部分实施例，而非全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
实施例一：
请参阅图1，本发明实施例提供的一种激光冲击层裂缺陷的超声检测方法，所述超声检测方法包括如下步骤：
S1：对复合材料进行超声检测，获取超声信号初始值；
所述复合材料包括复合材料一和复合材料二，复合材料一和复合材料二分别代表不同的材料相粘合，复合材料一和复合材料二相粘合，粘合层为粘合界面。
通过超声检测对复合材料进行初始检测，得到超声信号初始值，所述超声信号初始值包括幅值和声时等信号特征值，所述幅值为出声波传播有效直达波的最大幅值，所述声时为出声波传播有效直达波的传播走时。
其中，
S101：判断超声信号初始值是否在预设阈值范围内；
S102：当超声信号初始值不在预设阈值范围内时，则确定复合材料的质量；
S103：当超声信号初始值在预设阈值范围内时，则执行S2。
其中，所述预设阈值范围指的是在复合材料制造要求的超声检测的合格范围或复合材料制造标准的超声检测合格范围；即判断超声信号初始值是否在预设阈值范围内是为了确定复合材料的在进行下面的超声检测前是否符合复合材料制造要求，当超声信号初始值不在预设阈值范围内时，即复合材料的内部已经出现了缺陷，此时可以直接将复合材料定性为不合格产品，对于不合格的产品就没有必要进行下面的超声检测了，直接可以通过相控阵列的等的方法可以得到复合材料的缺陷形状和缺陷位置。当超声信号初始值在预设阈值范围内时，即复合材料符合制造的要求，因此可以继续进行超声检测。
S2：对复合材料进行激光冲击，获取冲击后的复合材料；
其中，在对于激光冲击的时候，需要选择激光冲击的功率，当复合材料为已知材料时，则根据已知材料的粘合强度将激光冲击的功率设置在所述已知材料粘合强度的合格阈值下限对应的功率开始进行冲击。对于已经知道的特别是使用过一段时间后的复合材料进行激光冲击的时候，选择在所述已知材料粘合强度的合格阈值下限对应的功率开始进行冲击主要是为了能够尽快的使复合材料产生缺陷，减少激光冲击的次数，节约能源。当复合材料为新材料的工件时，则根据预设初始值作为激光冲击的功率进行冲击。即对于新材料的工件对于粘合强度不是很清楚的时候，设定较小的预设初始值作为激光冲击的功率，以防止一开始就将复合材料冲击至脱粘的阶段。
S3：对冲击后的复合材料进行超声检测，获取超声信号特征值；
所述超声信号特征值包括幅值和声时等特征值。
S4：判断超声信号特征值是否等于超声信号初始值；
在复合材料存在或出现缺陷的时候，通过对复合材料进行超声检测，得到的超声信号特征值会发生变化，因此，通过对复合材料进行超声检测能够将复合材料内部粘接情况和缺陷的变化情况检测出来。通常，在超声信号特 征值不等于超声信号初始值时，即复合材料出现缺陷。通过判断超声信号特征值是否等于超声信号初始值来确定在受到激光冲击后复合材料是否发生改变，即复合材料是否出现缺陷。
S5：当超声信号特征值不等于超声信号初始值时，则获取当前激光冲击的功率并根据当前激光冲击的功率获取复合材料开始脱粘的粘接强度以及执行S7；
当超声信号特征值不等于超声信号初始值时，即复合材料开始出现缺陷，可以根据此时激光冲击的功率得到复合材料的粘合界面开始出现缺陷的粘接强度。继续执行S7。并且获取当前激光冲击的功率并根据当前激光冲击的功率获取复合材料开始脱粘的粘接强度。
S6：当超声信号特征值等于超声信号初始值时，则重复执行S2-S6并增大S2中的激光冲击的功率；
当超声信号特征值等于超声信号初始值时，即复合材料未出现缺陷，亦即确定复合材料无缺陷、粘合质量好。再继续增大激光冲击的功率对复合材料进行冲击，冲击完成后对复合材料进行超声检测，得到每次冲击完成后超声检测的超声信号特征值，直至当超声信号特征值不等于超声信号初始值时，即复合材料开始出现缺陷的时候为止。
S7：重复执行S2-S3并增大S2中的激光冲击的功率并判断前一次冲击后的复合材料测得的超声信号特征值与后一次冲击后的复合材料测得的超声信号特征值是否相同；
继续对复合材料执行S2和S3，即对复合材料进行激光冲击和超声检测，当复合材料出现缺陷后，继续复合材料继续增大激光冲击的功率进行冲击，会将复合材料最后冲击到超过复合材料的粘接临界状态，直至复合材料完全脱粘，此时通过超声测量得到的超声信号特征值是不发生改变了，即通过判断前一次冲击后的复合材料测得的超声信号特征值与后一次冲击后的复合材料测得的超声信号特征值是否相同，来判断复合材料是否完全脱粘了。
S8：当前一次冲击后的复合材料测得的超声信号特征值与后一次冲击后的复合材料测得的超声信号特征值不相同时，则重复执行S7；
当前一次冲击后的复合材料测得的超声信号特征值与后一次冲击后的复 合材料测得的超声信号特征值不相同时，即复合材料还在进一步扩大缺陷，还未到复合材料脱粘的临界点，因此，继续加大对于复合材料的冲击，直至复合材料脱粘的时候。
S9：当前一次冲击后的复合材料测得的超声信号特征值与后一次冲击后的复合材料测得的超声信号特征值相同时，则获取后一次冲击复合材料的激光冲击的功率；
当前一次冲击后的复合材料测得的超声信号特征值与后一次冲击后的复合材料测得的超声信号特征值相同时，即复合材料发生了脱粘的情况，此时获取后一次冲击复合材料的激光冲击的功率即将复合材料冲击到脱粘时的激光冲击功率。
S10：根据后一次冲击复合材料的激光冲击的功率，获取复合材料的粘接强度。
S11：根据相控阵列对复合材料进行检测，获取复合材料的缺陷形状和缺陷位置。
通过相控阵列能够实时的对复合材料从发生缺陷到脱粘的过程进行监测，得到复合材料的缺陷形状和缺陷位置，能够进一步提升超声检测的功能，有利于检测人员采集更多的检测信息，以便对复合材料的粘接性具有更多的数据分析。
S12：根据各激光冲击的功率、超声信号初始值和各超声信号特征值，生成复合材料的粘接强度性能曲线。
根据各激光冲击的功率、超声信号初始值和各超声信号特征值，激光冲击的功率置于X轴，将超声信号初始值和各超声信号特征值置于Y轴，生成复合材料的粘接强度性能曲线，通过复合材料的粘接强度性能曲线能够清晰的得到，在激光冲击功率发生变化的时候，超声信号特征值发生的变化，即可以知道复合材料内部界面发生的变化，能够有利于检测人员对于复合材料对于粘接性的分析。
根据后一次冲击复合材料的激光冲击的功率，能够直接得到激光冲击的强度，从而确定复合材料的粘接强度。实现了对新开发的或新生长的复合材料的粘接强度极限质量检验、对已经使用复合材料工件的合格性进行检验提 供一种高效、连续、实时、少扰动形式的测量，尤其是复合材料工件的检测，具有无破坏性的特点。
本实施例提供的超声检测方法具有高效、快速、自动的特性，实现了临界缺陷或者缺陷初始状态的检测，而且就连续增量功率激光冲击，可以实现新产品性能全过程检测、以及实现在使用过程的产品受力及振动范围内的合格性检测。本实施例提供的超声检测方法检测效率高，激光冲击时间可以控制在ms级以内，超声检测可以控制在秒级以内，加上中间移动定位时间，因此一次冲击加上检测可以3-5秒左右时间完成，最终总时间可以根据激光冲击功率的增量来计算，比已有的粘接力测试整个制作和测量过程的效率大大提高。实现了粘接界面的缺陷发生到脱粘过程的检测，得到最终复合材料的粘接强度。进而解决了现有技术中存在复合材料的粘合界面的潜在缺陷或者处于临界状态的缺陷无法检测出来的技术问题。
