Examples of our Collaborations
1) A fabric company.
Tasks: To provide a full-range development from meso- and macro mechanics modeling to improve fiber architecture; to laminate and ply drop optimization; static, fatigue and CAI predictions and validating data, and marketing.
Challenges: To demonstrate multi-scale methodology, and optimization to replace empirically based or outdated practices.
In-kind support: $500,000 per year.
2) A materials supplier.
Task: To provide micro mechanics modeling and statistical database to support the manufacturing of a prototype structure with the goals of bridging the coupon data with structural performance prediction, and defect mechanics that can assess the effects and recommended accept/repair/reject decision.
Challenges: To demonstrate predictability of cure cycle, size effect and a rational defect mechanics.
In-kind support: $400,000 per year.
3) A racing aircraft manufacturer.
Tasks: In support of converting a fiberglass aircraft to partially carbon composites in order to increase payload. Most likely components will be converted to carbon composites and validate performance increase prediction.
Challenges: To demonstrate systems performance prediction is practical leading to reduced weight and cost with increase in overall performance.
In-kind support: $200,000 per year.
4) An equipment supplier.
Tasks: To increase software/hardware performance such that a fully integrated Digital Image Correlation with corresponding Finite Element Analysis. This system will form a generic system that can revolutionize design allowable generation, defect detection of small and large components, and defect mechanics to determine accept/repair/reject criteria.
Challenges: Fast and converging solutions that can be packaged into portable, robust and easy to use systems.
In-kind support: $400,000 per year.
5) An automated manufacturing machine supplier.
Tasks: To develop automated process for laying multi-angle tape so as the achieve higher quality panel with faster speed and lower scrap rate through 1- or 2-axis layup (instead of 3- or 4-axis). Specially engineered laps in successive layers will ensure uniformity in panel thickness and properties at a substantially reduced cost.
Challenges: Novel design of multi-angle tape with unique ply angles allows laps and staggering so outstanding panel quality and performance can be maintained with conventional machines without modification.
In-kind support: $300,000 per year.
6) A engineering consulting firm.
Tasks: Support of a US Army Phase II program on fatigue life prediction module and integration with Abaqus and Natran FEA programs. This unique life prediction is derived from a micromechanics model where matrix is assumed to be isotropic that follows Goodman’s diagram, while carbon fibers are linear elastic and orthotropic.
Challenges: Fatigue life of an isotropic medium like epoxy resin can be based in two parts: the mean and alternative stresses. Their combinations will lead to different stress ratios from tension-tension, compression-compression, to tension-compression. A systematic prediction of different materials, laminates, and combined stresses can be built from this separation of constituents by micromechanics.
