Filling glass fiber (GF) to polypropylene (PP) is a common reinforcement method aimed at improving the material's mechanical properties, such as rigidity, strength, and heat resistance. However, the addition of glass fiber can indeed affect the material's toughness and fracture behavior, potentially making it more brittle.

What is a resin manhole cover? This is a question many people often ask. Is a resin manhole cover just a plastic manhole cover? Resin Manhole Cover (Composite Manhole Cover) A composite manhole cover is a type of inspection cover made by using polymers as the base material, combined with reinforcing materials and fillers through a specific manufacturing process. In fact, a resin manhole cover—also...

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...
