Résumé : |
Changes in VBO (vacuum bag only) prepreg properties were tracked as a function of room temperature aging time (out-time). A modulated differential scanning calorimetry method was used to characterize the prepreg, and changes in prepreg tack levels were examined using an energy of separation technique. Laminates were cured from prepreg at various levels of aging using both traditional autoclave processing and low-pressure vacuum bag only (VBO) techniques. Cured laminates were examined using ultrasound scanning, mechanical properties were tested, and laminates were sectioned for examination of microstructure. Laminate quality as a function of out-time is discussed in terms of prepreg properties and manufacturing technique. |
