Thermal rheological analysis of cure process of epoxy prepreg
The cure process of epoxy prepreg used as composite pipe joints was studied by means of differential scanning calorimetry (DSC), Bohlin Rheometer and other techniques. Isothermal DSC measurements were conducted between 110 and 220 oC, at 10 oC intervals. The results show that the complete cure …

Investigation of Processing Conditions and Viscoelastic Properties on Frictional Sliding Behavior of Unidirectional Carbon Fiber Epoxy Prepreg
… tool-ply friction of unidirectional carbon fiber epoxy prepreg at various contact pressures, temperatures and sliding velocities. Viscoelastic properties such as the complex viscosity (η*), storage modulus (G'), loss modulus (G"), and loss factor (tan δ) were used to determine the critical …

Fundamental Behavior of Nanoporous Networks in the Out-of-Autoclave Manufacturing of Carbon Fiber Reinforced Polymer Composites
… structural CFRP composites, especially in prepreg form, is often completed via autoclaves where elevated temperatures and pressures of typically 180 ◦C (350 ◦F) and 0.7 MPa (7 bars), respectively, are applied to cure the polymer matrix and compress the constituent laminae together. However, …

AEROMECHANICS OF A DOUBLE ANHEDRAL TIP COMPOSITE ROTOR: EXPERIMENT AND MODELING
… were built in-house using IM7/8552 graphite/epoxy prepreg weave. They were instrumented for strains and structural loads measurement. A two-bladed hingeless hub was designed and fabricated for the vacuum chamber to measure rotating frequencies (fan plot). The hover tests were performed on the …
