Abstract: The disclosure relates to the battery field and a PEO film, a preparation method thereof, and a solid-state battery are provided. A molecular structure of the PEO film includes a structural unit B, and the structural unit B includes —CH?CH—O—.

Abstract: Methods are provided for joint performance validation and include preparing a coupon from a blank by bending the blank to have a pair of legs disposed at substantially ninety degrees relative to each other. Another coupon is prepared by forming an opening in a segment of another blank and bending the segment approximately ninety degrees. The segment is disposed adjacent an end of the second blank. A test sample is prepared by joining the coupons together at a joint with a leg attached to the segment approximately at a center of the leg. The test sample is subjected to a force test to generate data for the performance validation.

Abstract: A method of evaluating the structural integrity of a component such as a vehicle component includes receiving signals from radio frequency identification (RFID) tags embedded in the component. The signals received are then compared to stored data indicative of sets of signals and that is correlated with different physical conditions of the component. A level of structural integrity of the component is then determined based on the comparison. The RFID tags may be wirelessly activated by an RFID reader to generate the signals. The comparison and determination may be carried out by a processor of an RFID reader. A system for evaluating the structural integrity of a component is also provided.

Abstract: A reinforced structural assembly includes a first vehicle component and a second vehicle component attached to the first vehicle component to define a substantially closed cavity. An acoustic foam member is contained within a container, also referred to as a vehicle pouch, containing the acoustic foam member and is made of a material that has a predetermined strength. A sealant with adhesive properties is included on at least a portion of an outer surface of the container, and is impregnated within or coated onto the container. The container and the acoustic foam member substantially fill the cavity so that the outer surface of the container contacts at least a portion of an inner surface of the vehicle components and the sealer seals the acoustic foam member and adheres the container to the inner surface of the attached vehicle components. A method of reinforcing vehicle components is provided.

Abstract: Methods, program products, and computer systems for estimating a stress of a toughened structural adhesive polymer are provided. One method comprises selecting a strain, a strain rate, a temperature, or a combination thereof at which the stress is to be estimated. A value of a strain-hardening stress of the toughened structural adhesive polymer is determined, wherein the value of the strain-hardening stress is dependent on the temperature and the strain. A value of a non-strain-hardening stress of the toughened structural adhesive polymer is determined, wherein the value of the non-strain-hardening stress is dependent on the strain, the strain rate, and the temperature. The value of the strain-hardening stress is added to the value of the non-strain-hardening stress to obtain an estimated total stress.
