Abstract
There is growing interest for the reused composite oriented strand board (COSB) for stiffness- critical and contoured applications. COSBs are made of rectangular shape prepreg strands that are randomly oriented within the structure. Development of this product form could markedly reduce the scrap generated during aerospace manufacturing processes. COSBs retain high modulus and drapability during processing and manufacturing. However, before any material can be deployed in industrial applications, the mechanical properties must be well understood so that proper design analysis can be performed. COSB has complex structure due to the randomly oriented prepreg strands, and this makes it difficult to model the stiffness using conventional methods. In general, a purely experimental hit and trial approach is used to design components out of such material. In this paper, a finite element based modelling approach to predict the stiffness of COSB is presented. A number of finite element models are developed using different meshing and contact techniques including orphan meshing, embedded elements, tie constraints and cohesive surface and cohesive elements. The model is validated with experimentally determined stiffness of COSB samples manufactured using Out of Autoclave (OoA) heated tool compression molding. Introduction
