Effect of Consolidation Time in Hot Press Compression Molding of Continuous Carbon Fiber‐Reinforced Polyetheretherketone Composite

open access: yesPolymer Composites, EarlyView.
Influence of consolidation time on interlaminar shear strength and void content after hot press consolidation and vacuum bag only processes. ABSTRACT Processing long fiber reinforced thermoplastic composites such as polyaryletherketones with carbon fibers (CF/PEEK) has found interest in the aerospace industry due to short‐time manufacturing and ...

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

open access: yesPolymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Anticlastic Curvature and Material Freedom

open access: yesphysica status solidi (b), EarlyView.
Anticlastic curvature occurs in bent bars for positive Poisson's ratio; synclastic curvature occurs for negative Poisson's ratio provided the material is homogeneous and elastic. Some planar negative Poisson's ratio materials exhibit anticlastic saddle curvature rather than convex curvature in bending due to effects of 3D structure.
