内容简介

Carbon/PEKK floor beams prove production worthiness of lower cost, fast coconsolidation process. Although reinforced engineering thermoplastics have lagged behind thermosets in aircraft structures, they offer compelling design advantages: low weight, inherent toughness and elongation, high service temperature (depending on the matrix) and good fire/smoke/toxicity performance. Thermoplastics also process faster and, unlike thermoset prepregs, store at room temperature. Already a successful proponent of aircraft thermoplastics (see "Learn More," p. 96), Stork Fokker AESP, B.V. (Hoogeveen, The Netherlands), research partner the Dutch Aerospace Laboratory (NLR) and several material suppliers have for years explored these attributes in primary structure, using optimized material forms and automated processing. While the parts developed to date are demonstrators, Arnt Offringa, Stork Fokker director of R&D, says there is "strong interest" in the concept from more than one aircraft manufacturer.
