| Résumé : |
Injection boxes offer various benefits in pultrusion regarding the reaction speed of resins as well as reduction of volatile emissions for traditional materials. To leverage these benefits, IKV is investigating the flow field dynamics practically in a distinctively developed transparent injection box. |
