Unidirectional carbon fiber enhances prepreg and is much larger than in the thermal expansion coefficient of machine direction perpendicular to the hot swollen of machine direction
Swollen coefficient, therefore in unsymmetric laminates or mixed metal layer unsymmetric laminate, not due to thermal strain remaining between laying
Match, causes unsymmetric laminate is internal after hardening to generate biggish residual thermal stress, and then generate apparent curing deformation.Test
And theoretical research is shown, asymmetric compound material laminate will generate large deformation, therefore unsymmetric laminate with the variation of temperature
It can be used as bearing structure and deformation element simultaneously.Therefore, application of the bistable laminate on deformable structure causes to learn both at home and abroad
The concern of person.
