Embodiment Construction

[0018] [0018] Embodiments of the present disclosure provide material efficient tooling for forming thermoplastic composite (TPC) laminates and laminated parts using continuous compression molding (CCM) techniques. As described in more detail below, laminated panels and laminated parts can be manufactured in a continuous process that reduces material waste. Embodiments of the present disclosure may be used in a wide variety of applications and are particularly suitable for forming TPC hardened components for aircraft applications which may include, but are not limited to: fuselage skins, wing skins, control surfaces, Door and access panels, joists, beams and deck beams. Various component cross-sectional geometries that can be manufactured include, but are not limited to, I-shaped cross-sections, Z-shaped cross-sections, U-shaped cross-sections, T-shaped cross-sections, and the like. These pieces may be of uniform or non-uniform thickness and may be curved or straight along the...

Abstract

Thermoplastic laminates are fabricated in a continuous compression molding production line. A lay-up of laminate plies is placed in a recess on a carrying tool, and the tool is moved through successive forming operations on the line, including preforming and consolidation operations. The tool is separated from the fully formed part at the end of the line and may be reused. Use of the carrying tool reduces material scrap.

Description

Background technique [0001] [0001] The present disclosure relates generally to processes and apparatus for continuous compression molding of composite thermoplastic laminates, and in particular to methods of continuous compression molding and associated molds that reduce the amount of material required to manufacture laminates . [0002] [0002] Continuous compression molding (CCM) is a process for manufacturing continuous lengths of thermoplastic composite (TPC) laminates. A CCM process is described in German patent application DE 4017978 C2 published on September 30, 1993. This process enables the production of TPCs of different shapes and sizes in a semi-continuous manner. Long or continuous lengths of laminate stacks are fed through a preforming operation where they are formed into a continuous predetermined form which then passes through a consolidation operation. The consolidation operation area includes continuously operating compression molding presses that press the...
