Vehicle Partition Panel Composite Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle partition panels face challenges in weight reduction and material compatibility issues due to the use of metal frames and composite material reinforcements, leading to increased weight and potential delamination from material mismatch.
Innovation Solution
A partition panel design where a reinforcement part made of composite material is integrated with a panel part also made of composite material, featuring a multilayer structure with differently angled reinforced fiber layers and intersecting reinforcement tapes to enhance strength and rigidity, while minimizing weight and ensuring compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a metal panel main body is used for vehicle partition panels, then strength and rigidity are improved, but vehicle frame weight increases
Solution Approach 1:
The invention replaces the metal panel main body with a composite material panel consisting of multiple fiber layers (carbon fiber, glass fiber, aramid fiber) stacked and bonded together. This composite structure provides comparable strength and rigidity to metal while significantly reducing weight, directly resolving the contradiction between strength and weight
Solution Approach 2:
The invention applies reinforcement parts made of the same composite material at specific locations where additional strength is needed, rather than using uniform metal reinforcement throughout. This localized reinforcement approach maintains overall strength while minimizing weight increase
2Strength
If a reinforcement body formed of composite material is attached to or molded integrally with the metal main body, then reinforcement is achieved, but defoliation occurs due to impact from combination of different materials
Solution Approach 1:
The invention uses the same composite material for both the panel main body and the reinforcement parts, ensuring homogeneous material properties throughout. This eliminates the defoliation problem caused by bonding dissimilar materials (metal and composite) together, as both components are now made from compatible composite materials with matching thermal expansion and bonding characteristics
3Strength
If reinforcement parts are added to strengthen critical areas, then strength and rigidity are improved, but device complexity increases
Solution Approach 1:
The invention integrates the reinforcement parts directly into the panel main body as an integral composite structure, rather than attaching separate reinforcement components. The reinforcement layers are stacked and bonded within the same composite manufacturing process, simplifying the overall structure and eliminating additional assembly steps while maintaining enhanced strength and rigidity

AI summary
Disclosed are a partition panel for vehicles and a method of manufacturing the same. The method includes mounting a first prepreg formed to have a shape corresponding to a molding groove on a lower die provided with the molding groove. The molding groove is inclined upwards from the center of a lower portion of the lower die to opposite ends of the lower die. A second prepreg having a sheet type is mounted on the lower die so as to cover the first prepreg. The first prepreg and the second prepreg are integrally molded by placing an upper die on the lower die.
