Additive manufacture of dissolvable tooling for autoclave processing of fiber reinforced polymer composites
Autoclave processing of advanced fiber reinforced polymer composites (AFRPC) uses applied heat and pressure to yield high quality composite components. Geometrically accurate and thermally stable molds or tools are used to maintain the part form until the part cures and rigidizes. For high-volume …

Development and implementation of robust large deformation and contact mechanics capabilities in process modelling of composites
Autoclave processing of large scale, one-piece structural parts made of carbon fiber-reinforced polymer composite materials is the key to decreasing manufacturing costs while at the same time increasing quality. Nonetheless, even in manufacturing simple flat parts, residual strains and stresses are …
