Product creep performance substandard
Problem Phenomenon
The product continuously deforms under long-term constant load
Cause Analysis
Pure PP has poor creep resistance; stress relaxation at the fiber-matrix interface; glass fiber orientation inconsistent with the load direction
Solution
Increase glass fiber content to enhance creep resistance; use high molecular weight PP to improve matrix creep resistance; optimize fiber orientation to be parallel to the main load direction
Key Takeaway
The creep performance of LGFPP depends on effective load transfer of the fiber skeleton
