近年来，聚合物金属复合材料（PMH）技术越来越多地用于替代全钢承重结构部件，特别是汽车前端模块。本文研究了铝板表面形貌、注射成型工艺参数和聚合物与金属之间的粘附性之间的关系。为此，用喷丸强化铝板制备了几个模具表面。用剪切试验测定附着力。采用不同的显微技术：光学显微镜用于统计表征不同工艺条件下的粘附，扫描电子和扫描探针用于表征微观和纳米尺度上的粘附现象。(c) 2011年cirp。
In recent years the direct-adhesion polymer metal hybrid (PMH) technology has been increasingly used in replacing all-steel load-bearing structural components especially in automotive front-end modules. This work investigates correlations between the surface topography of aluminum sheet, injection overmolding process parameters and adhesion between polymer and metal. To this end several mold surfaces were prepared by shot peening aluminum sheets. Adhesion was measured using the shear test. Different microscopy techniques were implemented: optical microscopy for statistical characterization of adhesion at different process conditions, scanning electron and scanning probe for characterization of the adhesion phenomenon at the micro- and nano-scale.
