An Evaluation and Comparison of Mechanical Properties of Phenolic-Glass Fabric Composites Prepared by Vacuum Bag-Only and Autoclave Processes [PDF]

علوم و تکنولوژی پلیمر, 2023
Hypothesis: The curing process for phenolic resin composites is always carried out under press or autoclave pressure, as water by-products are released during curing process. As a result, when phenolic composite parts are formed using the vacuum bag-only
