汽车行业对成本非常敏感。这就是为什么片状模塑料（SMC）压缩成型是该行业中最流行的纤维增强聚合物复合材料制造方法的主要原因之一。SMC压缩模塑的经济性比树脂传递模塑或其任何变体等工艺更适合汽车工业。对于汽车SMC模塑机来说，要利用碳纤维提供的额外刚度，作为广泛使用的玻璃纤维的替代品，制造工艺需要尽可能简化。在SMC的实际制造中，联合收割机玻璃纤维与碳纤维的结合并不容易，将仅含碳纤维的SMC层片与仅含玻璃纤维的SMC层片结合在一起会方便得多，而将仅含碳纤维的SMC层片与仅含玻璃纤维的SMC层片结合在一起会方便得多。联合收割机这也将允许通常只使用基于玻璃纤维的SMC的模塑商从单独的供应商那里获得碳纤维SMC，并且只在经济上有意义的情况下使用。本研究的主要目的是研究在每层的基础上，用碳纤维代替玻璃纤维，可以实现物理性能的相对改善。Polym.康波斯27：718-722，2006.© 2006塑料工程师学会
The automotive industry is extremely cost sensitive. This is one of the main reasons why sheet molding compound (SMC) compression molding is the most popular fiber-reinforced polymeric composites manufacturing method in this industry. SMC compression molding economics are better suited for the automotive industry than processes such as resin transfer molding or any of its variations. For automotive SMC molders to take advantage of the added stiffness provided by carbon fibers, as an alternative to the widely used glass fibers, the manufacturing process needs to be simplified as much as possible. In actual manufacturing of SMC it is not easy to combine glass fibers with carbon fibers; it will be a lot more convenient to combine SMC plies only with carbon fibers together with SMC plies with only glass fibers. This will also allow molders that will normally use only glass fibers-based SMC to secure carbon fiber SMC from a separate supplier and use it only where it makes economic sense. The main purpose of this study is to investigate the relative improvement in physical properties that can be achieved by substituting glass fibers by carbon fibers in a per ply basis. POLYM.
