A macroscopic model of the compaction process during compression molding of carbon fiber sheet molding compounds

Volumetrical Characterization of Sheet Molding Compounds

For a comprehensive study of Sheet Molding Compound (SMC) surfaces, topographical data obtained by chromatic confocal imaging were submitted systematically for the development of a profile model to understand the formation of cavities on the surface. In order to qualify SMC surfaces and to predict their coatability, a characterization of cavities is applied. To quantify the effect of surface mo...

Characterizing the Mechanical Properties of Callaways Forged Carbon Fiber Reinforced Sheet Molding Compound

The Numerical Analysis and Validation of Compression Molding Process

In this work, the simulation results from a program developed for the three-dimensional analysis of compression molding of thermoset composites were compared to the experimental results of an actual molded thermoset sample. The program predicts the flow pattern, fiber orientation, fiber length distribution, curing of the resin and mechanical properties. The comparison between simulation and exp...

Solution for Carbon fiber Wet-Out Issue for Low Cost Sheet Molding Carbon Fiber Composite Production1 Continental Structural Plastics

Poor wetting leads to underperforming composite properties and has been a major obstacle in implementing low cost carbon fibers in SMC parts. The objective of this project is to solve the technical challenge of poor carbon fiber wet-through during Sheet Molding Composite (SMC) process. Continental Structural Plastics (CSP) partnered with ORNL to develop a new sizing technique called Point Sizin...

Precision Injection Molding PRECISION PROCESS CONTROL OF INJECTION MOLDING

1 INTRODUCTION The technical requirements of precision injection molded components demand a heightened level of process performance, and with corresponding process monitoring and control technologies. To obtain the desired critical to quality attributes (CTQs) of the molded products, the injection molding process must be consciously designed such that the key process variables (KPVs) are observ...
