The matrix has a strong influence on several mechanical properties of the composite such as transverse modulus and strength, impact resistance, shear properties and properties in compression. This paper describes the results of an experimental study to determine the effect of resin (matrix) on the post-impact compressive behaviour of carbon fibre woven laminates. Three new low temperature cure (50–125°C) epoxy resins are examined: an unmodified (LTM12), a rubber-modified (LTM25) and a thermoplastic toughened epoxy resin (MT8E). Note, however, that the first two are post-cured at 190°C. Velocities and impact energies were used to simulate momenta typical of low velocity impact hazards associated with aircraft in-service. Measurements of impact damage and damage growth during compression are made using ultrasonic C-scanning and penetrant-enhanced X-ray radiography techniques. For low impact energies the superior performance of the thermoplastic toughened epoxy is confirmed. Its residual compressive strength compares favourably with that obtained for high strength carbon fibre/epoxy laminates manufactured from unidirectional sheets cured at 190°C.</p></div>","PeriodicalId":100296,"journal":{"name":"Composites","volume":"26 9","pages":"Pages 661-667"},"PeriodicalIF":0.0,"publicationDate":"1995-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0010-4361(95)98915-8","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74462010","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}

Because the properties of an end product depend upon the selection of processing conditions, it is essential that the conditions under which a well consolidated part is obtained should be defined. To investigate the effects of individual process parameters from a minimum number of tests, the Taguchi method is applied. For this investigation, PEEK/carbon fibre (APC-2) thermoplastic composite rings were manufactured by a thermoplastic tape winding process at selected conditions, and the influence of dominant process parameters on interply bond strength was evaluated. The influence of three dominant factors, namely laser power, consolidation pressure and tape speed, on bond strength were investigated. The experimental design involved using L<sub>9</sub> orthogonal arrays, and the percentage contribution of each factor to the quality of bonding was estimated by the ANOVA technique.</p></div>","PeriodicalId":100296,"journal":{"name":"Composites","volume":"26 9","pages":"Pages 669-673"},"PeriodicalIF":0.0,"publicationDate":"1995-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0010-4361(95)98916-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80869200","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}

Two laminate lay-ups were studied: cross-ply, [0/90]<sub>2s</sub>, and unidirectional, [0]<sub>8</sub>. At first, the fatigue limit based on one million cycles was established for the tension-tension fatigue condition. Then, the fatigue response under fully reversed (tension-compression) cycling loading with a maximum stress equal to the tension-tension fatigue limit was investigated. This tension-compression loading resulted in an increased amount of damage and ultimately led to the specimen failure well before one million cycles. In the cross-ply laminate, the damage mechanisms in the 90° plies involved transverse cracks only during tension-tension cycling, and transverse and longitudinal cracks during tension-compression cycling. In the unidirectional laminate, the longitudinal cracks which initiated at the hole periphery grew longer in tension-compression fatigue than in tension-tension fatigue. On the other hand, no damage and consequently no effect on fatigue life was observed during the compression-compression fatigue condition only.</p></div>","PeriodicalId":100296,"journal":{"name":"Composites","volume":"26 9","pages":"Pages 631-636"},"PeriodicalIF":0.0,"publicationDate":"1995-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0010-4361(95)98911-4","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72560523","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}
