A Quick Guide to Rigidity and Flexibility in Polymer Materials
2025-06-05
When discussing polymer materials, we often hear comments like “this material has excellent rigidity” or “that one has outstanding toughness.” Materials with high rigidity usually exhibit greater hardness and resistance to compression and deformation. On the other hand, tough materials are more like flexible ribbons, capable of withstanding stretching and bending with remarkable resilience. But ha...

Automotive Interior Odors: An Unavoidable Challenge for Material Engineers
2025-07-10
Odor is both a sensory experience and a perceived measure of quality. In the confined space of a car cabin, the "new car smell" from plastics is not a symbol of luxury—instead, it often becomes a major source of consumer complaints. This article, grounded in engineering practice, systematically explores the sources, mechanisms, analytical methods, and controllable strategies related to odor. It ai...

Composite Material Repair: Process, Methods, and Key Points
2025-09-01
Overview Composite material repair refers to the technology of restoring the mechanical properties, structural integrity, and functional performance of composite components (such as carbon fiber reinforced composites and glass fiber reinforced composites) that have been damaged during use or processing (e.g., cracks, delamination, holes, wear). With advantages such as high specific strength and ex...
