Lily H. Shu.al. This paper describes efforts towards product design that facilitates remanufacture.
Insights on how to design products for ease of remanufacture were obtained from literature and
collaboration with remanufacturers. The most essential aspect of design for remanufacture was found to
conflict with other design-for-x methodologies, such as design for assembly and design for recycling.
Design for remanufacture was therefore viewed in the context of other life-cycle domains, specifically
manufacture and assembly, maintenance, and scrap-material recycling. Since fastening and joining
issues are common to all these domains, a framework that evaluates the effect of joint design on each of
these life-cycle stages was developed. This framework estimates the cost of remanufacture relative to
other life-cycle costs determined by the joint design, and was applied to case studies of joints that did
not facilitate remanufacture. [2]

Akinshin, et.al. This study explores the creation of a business that manufactures custom spare parts

J. Troschitz, et.al. This study developed a versatile insert geometry that allows thermoplastic
composites (TPC) to be effectively joined with metals using clinching or resistance spot welding (RSW).
By embedding metal inserts into TPCs during manufacturing without damaging the reinforcing fibers,
the method enables compatibility with existing metal joining techniques. Using glass fiber-reinforced
polypropylene sheets, the research tested the inserts through microsections and single-lap shear tests.
Results showed that the inserts produced strong, high-quality joints with both methods, proving their
