The aim of this study was to elaborate on the methods of constructing combined components of a car mirror. The components were made of materials with different thermal expansion coefficient. The basis for the research were numerical simulations prepared in Moldex 3D software. The external cover of a mirror would be made of carbon composite based on epoxy resin (hereafter referred to as carbon), and the internal insert would be made of ABS. The adhesive bonding applied did not provide appropriate properties and led to breaks during usage. After carrying out moldflows it was found that the areas of breaks were determined by the places where fronts of flowing material met during the injection. The cause of breaking was diametrically different thermal expansion of both materials. This induced significant stresses in the adhesive layer. Finally, the effective solution was to change the geometry of the mirror insert made of thermoplastic ABS.

这项研究的目的是阐述构造汽车后视镜组合组件的方法。组件由具有不同热膨胀系数的材料制成。研究的基础是在Moldex 3D软件中进行的数值模拟。镜子的外罩将由基于环氧树脂的碳复合材料（以下称为碳）制成，内部插件将由ABS制成。所施加的粘合剂粘结不能提供适当的性能，并且在使用过程中会导致断裂。在进行铸模流动之后，发现断裂区域是由注射过程中流动材料的前沿相遇的位置所决定的。破裂的原因是两种材料的热膨胀截然不同。这在粘合剂层中引起明显的应力。最后，
