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 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.

The fibres deform so that the sample becomes barrel-shaped. A three-dimensional code has been developed to simulate this flow. The material is modelled as a transversely isotropic continuum in which the fibre direction is specified at each point by a vector a. The system of coupled equations is solved using a finite difference technique. The transverse and longitudinal viscosities are assumed to be functions of the fibre volume fraction which increases as the resin is forced to percolate parallel to the fibres. The stress equations of motion are discretized using central differences for a fixed orientation and the discretized equations are solved using a pseudo-time technique. The converged solution is then used to determine the change in fibre direction at each point of the continuum. The process is repeated in real time using the new fibre orientation. In the momentum equations, the viscous terms are treated explicitly and the pressure gradient implicitly. A projection method is used to ensure that the mass is conserved at each time step. The results are in broad agreement with the experimental observations and demonstrate the success of the continuum model to predict flow behaviour.</p></div>","PeriodicalId":100299,"journal":{"name":"Composites Manufacturing","volume":"6 3","pages":"Pages 263-268"},"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)95019-U","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85218513","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 IFRF theory for a viscous fluid with two inextensible directions is developed for modelling fabric sheets and specific forms of the constitutive equation are derived. Some simple flows are analysed and it is shown that in throughthickness shear flows, as for example in a torsion rheometer experiment, the fabric angle ϖ remains constant, whereas in in-plane flows ϖ is a function of the strain rate. Trellis deformations are investigated by considering the in-plane stretching flow of a fabric with fibres inclined to the load direction. The torsion rheometer test is analysed for a fabric pre-deformed to a fabric angle ϖ. In this case, tests on rectangular specimens with different aspect ratios and fabric angles are proposed which enable the three viscosities in the model to be determined.</p></div>","PeriodicalId":100299,"journal":{"name":"Composites Manufacturing","volume":"6 3","pages":"Pages 153-160"},"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)95006-K","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83414073","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}
