Abstract

Design tasks involving multiple complex requirements and constraints reveal the need for extensive materials research in the aerospace industry. This process requires researchers to innovate materials that conform strict design specifications. Reasons given for the advancement of materials neither abrogate material testing requirements nor supersede simplified design approaches. Structural design requires precise tracking of the elastic and strength properties of materials. Hence, tensile, flexural, and interlaminar shear properties are evaluated by the two-factor analysis method in this study. It provides a detailed search and analysis for every conceivable combinations of the factors’ levels through each complete test. The factorial modeling is proposed as a useful method while performing analysis on the mechanical properties rather than roughly providing averaged values for the tested materials.

Polimer Kompozitlerin Çok Yönlü Mekanik Özelliklerini Araştırmak için Faktöriyel Modellemenin Kullanılması

Abstract

Çoklu karmaşık gereksinimleri ve kısıtlamaları içeren tasarım süreçleri, havacılık endüstrisinde kapsamlı malzeme araştırmasının gerekliliğini ortaya çıkarmaktadır. Bu süreç, araştırmacıların yapısal tasarım özelliklerine uygun malzemeleri yenilikçi bir şekilde geliştirmesini gerektirir. İleri malzeme araştırmalarını gerekli kılan nedenler, malzeme test gereksinimlerini ortadan kaldırmaz ve basitleştirilmiş tasarım yaklaşımlarını geçersiz kılmaz. Yapısal tasarım, malzemelerin elastik ve dayanıklılık özelliklerinin hassas bir şekilde incelenmesini gerektirir. Bu nedenle, bu çalışmada çekme, eğilme ve tabakalar arası kayma özellikleri, iki faktörlü analiz yöntemiyle değerlendirilmiştir. Bu çalışma, her test sürecinde faktör seviyelerinin tüm olası eşleşmeleri için detaylı bir analiz sağlamaktadır. Faktöriyel modelleme, test edilen malzemeler için yaklaşık ortalamalı değerler sağlamak yerine, mekanik özellikler üzerine analiz yaparken kullanışlı bir yöntem olarak önerilmektedir.
