Modern thermoplastic polymers have improved mechanical and physical properties compared with their thermoset counterparts and, perhaps most important for industry, offer the possibility for rapid part production. As in tradational metal stamping, the current process and part design for thermoforming rely heavily on ‘trial and error’ practices which are costly, inefficient and provide little scope for optimization and understanding of the forming process. For efficient thermoforming information regarding temperature and pressure distribution, part thickness distribution, fibre orientations and potential regions of material defects must be determined. This paper presents some first results of an explicit finite element solution to simulate the forming process. At present a constant temperature process is assumed, however work is presently underway to include this effect.</p></div>","PeriodicalId":100299,"journal":{"name":"Composites Manufacturing","volume":"6 3","pages":"Pages 237-243"},"PeriodicalIF":0.0,"publicationDate":"1995-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0956-7143(95)95016-R","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85514740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aims of this contribution are: (1) to present results on laser-assisted high speed filament winding of pre-impregnated thermoplastic tapes and quasi-axial helical filament winding with direct flame, and (2) to compare different heating and pre-heating methods. The key issue in the application of thermoplastic tape winding is heating. Proper heating of pre-impregnated tapes during the on-line winding process can be achieved by a variety of methods: laser and infra-red radiation, hot gas and direct flame. It will be considered how the above heating methods affect the equipment and process costs, energy efficiency and response time.</p></div>","PeriodicalId":100299,"journal":{"name":"Composites Manufacturing","volume":"6 3","pages":"Pages 189-192"},"PeriodicalIF":0.0,"publicationDate":"1995-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0956-7143(95)95010-V","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90884183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
